Creating your own home used to be a complicated and expensive process with our ready-made self-constructed house plans all of the hard work has been completed so you can focus on enjoying it.

Architectural Plans Types:

Architectural plan types depending on the design of the house. And architectural design for houses in London can differ from the kind of the house. England’s most common types of homes are as follows: Detached, Semi-detached, Terrace, End of terrace, Bungalow, Cottage, Flat, etc.

1# The Bungalows

The bungalow is architecturally elegant, as all the rooms required have to get placed on one floor. Therefore, the right piece of land plays a significant role. Because the higher space requirement rooms have to get accommodated on one floor-the single-storey building takes up more space than multi-storey buildings. But no matter which property you build on, that we are going to plan your house flexibly and imaginatively and create the right living model together with you.

This often leads to the question: “Can I build a bungalow with a basement? The answer would be yes! There’s plenty of extra storage in a basement. After all, your future home has to meet your daily needs.

KPCL’s professional planners will also explain to you because there are many lots of options, the issue of which roof shape and which design best suits you. You choose whether it should be the ultra-modern flat roof with plenty of design space in the floor plan-or the gabled roof up to the underside of the roof.

2# Semi-Detached House:

You want a semi-detached house to build? Then KPCL is to you the right partner. Because in the KPCL semi-detached houses, the completely contradictory qualities-together and yet privately-unite in a unique way. Building a semidetached house also provides cost savings in addition to architectural finesse. For example, when buying the property or with the ancillary costs, which can be distributed over several shoulders, depending on the constellation.

3# Detached House:

Someone deciding the future to commit to a detached house will use heart and mind at all times. Anyone facing the decision in the future to invest in a detached house will always make use of heart and soul. That’s why things like quality comfort and feature are just as crucial as atmosphere, aesthetics, and a sense of space. Only if these features are mixed, private well-being can evolve in the future. We offer you a range of building benefits to allow you to enjoy comfortable planning and construction.

4# Flat Building:

Numerous completed works prove that our innovative timbered architecture is much more than suitable for classic Flat building. Combined with outstanding interior and exterior sound insulation, reliable quality makes these buildings a remarkable attraction for demanding tenants and solvents. We meet the unique requirements for fire prevention in every way. You have free design options as the owner of the building; you specify the floorplan as well as the residential unit section. Whether as a leased apartment or with several family members for your use.

5# Terrace House:

There’s a concept that you can’t pick your neighbors. But, it’s not the case unless you are building a terrace house. Why not join forces as well as build several homes along with friends or family? Of course, the advantage is the synergy and significant time and money savings. Especially if it’s a group of people, by building a terraced house, you can save a lot of resources.

You can depend on us at KPCL to offer an individual character to each particular terraced house. For all buildings, efficiency, stability, and durability seem to be of the highest priority.

A simple guide to Planning Permission

A Simple Guide To Planning Permission


# Planning Permission

First of all, What is Planning Permission? With the construction to your property, it being a new property from scratch or additions to expand your existing property, In addition, usually requires approval from your local authority in a form of planning permissions. The planning system designed to control developments so there are no inappropriate constructions.
You will need planning permission if you are building a house from scratch or an outbuilding that will be an annex to a house. It will need to have the right standards for a person to be living there and, if your extension exceeds the permitted development rights again you will need to apply for planning permission.

# Permitted Development Rights

Permitted Development rights, give you permission to perform certain types of work without planning permission. They granted from parliament, not local authorities. The Town and Country Planning Act on the 1st of July 1948 was the skeleton of the Permitted Development Right that we have todayThis act allows for minor improvements, such as converting a loft or modest extension to your home, to be undertaken without clogging up the planning system. England, Scotland, Wales and Northern Ireland each enjoy their own versions of these rules.

Permitted Development takes into consideration the location of the property (areas of natural beauty and conservation areas have different rules), and the amount of work already done to the property. The permitted development right to apply many typical projects for houses and do not apply to flats, maisonettes or other buildings. Commercial properties have a different permitted development right to dwellings.

# Planning Permission Cost

Planning the Permissions fee varies depending on what works you are planning to do. A Full Application, for a new single dwelling built in England, is £385, yet, in Scotland, Wales and Northern Ireland would be a different fee. For alterations or extensions to a single dwelling, included within the boundary in England is £172, where again in Scotland, Wales and Northern Ireland the fee will be different.

# What Are The Basic Form Requirements Of A Planning Application?

Each site varies with different information required. But common an application includes five copies of application forms, the signed ownership certificate, a site plan, block plan, and elevations of both the existing and proposed sites. A Design and Access Statement and the correct fee. Design and Access statement can do your designer, who is working with you on your alterations to your dwelling. Statements use to explain the access and concept of your alterations to your dwelling by explaining and justifying your proposal.

# What Are The Planning Conditions?

Planning permissions could grant permission subject to conditions that will need to discharge/agreed in a certain amount of time. Planning conditions are important as a failure to comply can result in a break of contract. Where there is no right of appeal. Conditions could be as little on have matching materials. To the existing dwelling or that all boundary treatments must agree.

# How Long Until The Decision?

Most planning applications usually decide within 8 weeks. If you are constructing something large and complex this could take up to 11-13 weeks. Usually, the authority will give you a rough timetable explaining when you would have your decision.

# How Long Do I Have To Begin Work?

Once you have your planning permissions you grant for three years. Where you can begin work on your dwelling in that time or you might have altogether. You can have small amendments by applying for a non-material amendment. Yet major alterations could involve a further application for Full planning permission, so discuss your plans with your LPA (local planning authorities) first.
If you carry out work without planning permissions it is not illegal, yet, if you haven’t informed anyone then the local authorities can take action to have the work altered or removed. Altering a listed building without permission is a criminal offense!

# 5 Things To Summarise About Planning Applications

  • You can make a planning application on any piece of land in the country.
  • Your planning decision should take no longer than eight weeks from the point of application.
  • The objections of neighbours and local people may well not have any impact on the final decision.
  • You can withdraw an application at any time — so if you think you are going to get a refusal, you can withdraw it at any time up to the day itself, and resubmit free of charge.
  • You can submit an infinite number of planning applic­ations on any one site — and choose which one to use. As long as it is current, you don’t have to use the most recent. is also a good website to get familiar with the guidelines whatever your development. But to be more specific the best place is your local authority’s planning permissions section.

Interactive information on the planning portal, you can select your building and go into detail on each section of your building of what building regulations you have to follow and what works you will need to apply for planning permissions, as well as suggestions to make your house greener(eco-friendly).

What Is An Architectural Project?


# Architectural Project:

The architectural project that gives information about the plans. Planning drawing, exterior appearance, the proportion of the masses, interior designs, and all the details of the building to construct call architectural projects.

# What Is An Architecture:

For centuries, people have been in need of suitable structures for shelter, education, culture, health, administration, defense, shopping and to continue their religious activities. The art of making these structures useful, sturdy, and beautiful-looking call architecture. “Architect” is the person who designs and manages them.
Architecture developed according to the living conditions in different parts of the world, economic, technical, and cultural formations. In this respect, the structures, which can survive to the present day. provide important information about how people lived.
In the past and the civilizations, they have established their styles and building materials. Among famous various Architecture firms in London, We inquired about the components of an architectural project.
In this blog post, we would like to enlighten you with this information. Let’s see! The architect starts work after the location of a building determines, the type decides and the cost is roughly calculatedThe three most important principles of architecture are robustness, functionality, and beauty.
In this respect, the structures, which can survive to the present day. provide important information about how people lived. In the past and the civilizations, they have established with their styles and building materials.
The fact that the structure is suitable and sheltered for environmental and climatic conditions should consider at the design stage.

# Initial Reviews:

All the works that must consider before starting architectural projects call the first examination. If we write these into items:  The architect makes the needs program considering the wishes and possibilities related to the project.

# Architecture, On-Site Review:

  • Checks the suitability of the plot to the diameter.
  • Checks the road network, sewerage, electricity, and related connections of the land.
  • Controls the north direction and landscape status of the plot.
  • Controls the trees, wells, pools, cisterns, etc. if any.
  • Examines the topographic situation.
  • Removes zoning status.
  • If the project presents any characteristics (such as factory, production farm, etc.). It receives the necessary information from the experts.
  • Examines climate conditions.
  • In light of these data, the architect develops a connection diagram using his professional knowledge and skills.

# Sketches:

This is the most important working period of the architectural project. These drawings and planning drawings are also called sketches. The rules to consider when preparing sketches are as follows:

  • Sketches draw approximately to the freehand squared and sketch papers.
  • Plan cross-sections and views draw according to the size of the building using 1 / 100-1 / 200 scale, and sitting plans using a 1 / 500-1 / 1000 scale.
  • Although the wall thickness is different, it draws as a single line.
  • The opinions of the knowers take.
  • Information exchange with engineers.
  • The surrounding architecture takes into consideration.
  • The life, customs, customs, traditions, and customs of the users will take into consideration.
  • The draft equipped with symbols such as people, animals, trees, and vehicles.
  • If necessary, the perspective draw and the model prepare.

# Pre-Project:

In this period, the project, which has matured with the sketches and found positive in all aspects, start with the tools. The preliminary project prepares by finding a suitable solution for a given subject according to the given program and land condition, and drawing the main ideas with a suitable scale (1 / 500,1 / 200,1 / 100) on the paper in the form of a floor plan, structure appearance, and section drawings and is a project given to the owner. The plans included in the final project given below:
  • Situation Plans
  • Plans (floor plans)
  • Sections
  • Views
  • Roof panels

# Final Project:

When the preliminary project hand over to the owner, the owner may like it or may not like it or request a change in it. Likewise, since the works related to the static and plumbing works, which are continuing in parallel with the architectural project works, become more definite as progress, some changes may see on the preliminary project due to these issues.
Problems solve in a way that satisfies all concerned. There will be no problem in the project that requires certainty and large changes. This project called “final project 1/ and it draws at a 1/50 scale or 1/100 scale according to the building size.
Plans to include in the final project are:
  • Site plans
  • Plans (floor plans)
  • Sections
  • Views
  • Roof plans
  • Suspended ceiling plan
  • Detail list

# Application Project:

The aim of all architectural and engineering project works; construction is to ensure that the desired structure is as intended. For this reason, a project draws to show all the details and details of the applications to make, and this project called the application project. The details and plans to include in the implementation project given below.

# Detail Drawings:

If the drawings in this section consisting of detail sections sketched before the plan, section, and views, which are the main drawings of the application project, can get more. The details in the list prepared during the final project period drawn using the scales specified in the same list
In this period; roof details required for construction, staircase, joinery, flooring, wall and ceiling cladding; architectural details of paint whitewash, lighting, heating, ventilation, and air-conditioning devices; dilatation, fixed furniture, and plumbing projects. 1/10 or 1/20 scale.

Detail Drawings Drawn Under 8 Titles:

  • General system details
  • Partial detail systems
  • Roof details
  • Staircase details
  • Joinery details
  • Suspended ceiling details
  • Wallcovering and paneling details
  • Special manufacturing details related to the function of the structure
  • Paint and coating details

# Plans:

These are the drawings that created with specific scales and rules and which make up the parts of the project for the construction of the building. The plans drawn in the application project are also called floor plans. Although the floor plans draw on a scale of 1 / 50-1 / 100 considering the size or the size of the building, the most used scale is 1/50.
The floor plans draw in such a way to provide any ease to the practitioner during the application.  All rooms and individual spaces numbered in the plans. On the plans, the areas of the individual sections, their dimensions, the type of coatings to make, the type of paints to make, the placement of the goods show.
Floor Plans are drawing under 6 names:
  • Basement floor plan
  • Ground floor plan
  • Normal floor plans (1st floor – 2nd floor… etc.)
  • Level/ floor plan
  • Drawing floor plan
  • Roof plans

# Sections:

The main entrance is the upper floor code ± 0.00 and all different heights give and at least one of each block must pass through both stairs and low flooring and at least 2 vertical plans are drawing. It is drawing on a scale of 1/50 or 1/100 depending on the size of the project. When we look at the cross-section plans, we only see the necessary heights such as door height, under-window height, window height, in-room wall height.

# Elevations:

They are the plans drawn from different fronts with different drawing techniques according to their vertical planes. Views on the door, window, balcony, rain gutters, windowsill bottoms, shield walls, ridge, eaves, and chimneys coded by drawing. Also, facade cladding material and colors write, mobility on the facade state and if necessary, notes take.

What Is An Architectural Design?


# Architectural Design

Architectural design focus on a certain law or understanding of beauty and functionality, the design of buildings, rooms, furnishings, sometimes even highways and trees on the highways. Architects can take part in architectural design, Architecture drawing as well as many individuals from distinct careers. Where suitable, architectural design may be the design of a furniture or construction venture, while the layout, structure, and shape of the trees on the road’s design.
The region is a broad architectural design spectrum. The layout of the building is more subjective than these. Only a particular structure joins the design cycle and as a consequence built. Well if you are typing for Architectural Services near me you are in right place. If you are in the market for architectural services, you need to have knowledge about architecture & functionality

# Architectural Functionality And Design

How should you understand the functionality and how does it relate to design?
Functionality can describe the quality of working and being useful. In the field of architectural design, it would be appropriate to examine it from two different angles. The first is technical functionality and the second is ergonomic functionality.

# Technical Functionality

The most important word that should explain technical functionality is production. Whether it’s a plumbing or opening the cabinet door without touching anything, it doesn’t matter at all. We can replicate these examples fair, but as I mentioned, the only criterion is whether it works or not.
The ladder you see in the photo on the left is also designed as a complete wall shelf and an open shelf system. In essence, it was a simple, simple and useful concept. The technical part is only to create and dimension the carrier system. The shelf dimensions and proportions of the ladder and the rung dimensions calculate to the exact dimensions. Here, our architect experience and knowledge come to the forefront.

# Ergonomic Functionality

Let’s go to the Ergonomic Functionality section. Today, many services and products provide in stereotyped standards by Ernst Neufert, who lives in Germany, dimensioned everything he found during his life with his drawing and created a kind of Architectural Encyclopedia, and many products manufactured today continue to design according to these measurements.
For this reason, the width of the countertop in our house considered 60cm, and the height of our countertops is 90cm. Exceptions can, of course, but remember that every change, it will come up as a detail that you need to think and even solve. For example, when you make your countertop at a depth of 80cm, not 60cm, if you need to think realistic, the hood will be lagging behind the stove and the performance will be very low and it will be more difficult to reach the top cabinets.
Or, if you consider changing the height of the counter, you may encounter a problem where you will have difficulty fitting the Dishwasher under the counter. Of course, the most important factor in the formation of measurements in this way relate to human body structure, that’s why we call it ergonomic functionality. The essence is to create a whole concept. Form follows Function  (Louis Sullivan)

# How Should We Combine Them All?

Ergonomics and technical binding criteria on one side, design on the other. It is difficult to put them together, but of course, it is possible. As you can imagine a house with sea view and sun, there may be people who say that they would be in such a house. Yeah, that would be nice. Each room in the house faces in different directions and captures the sea view from different angles. The sun also enters the desired rooms at different times.
This example gives in particular because the location and location of the building is a criterion of functionality. It is a technical necessity for a house to see the sun and turn to the landscape according to its location. The reason it’s an obligation is everyone, we all want to live in a beautiful house. No matter how different the interior design of the house is, the main features that increase the value of the house are the reflection and view of the light in the room. Of course, this may not consider finance,

# What Should Consider?

When it comes to the importance of the definitions of functionality that have explained aboveFirst, technical functionality is an area that does not accept errors and is the responsibility of your Architect. Second, ergonomic functionality, as mentioned, can transform into a personalized design. The important thing to understand is that you have the right to ergonomic interfere with some things, even if they limited.
It is important that you do not interfere with the technical issue, because it is the responsibility of architect and implementers. Of course, it is necessary to have enough time to reach such designs. It is not only a matter of experience in material selection, construction, and planning.
Here you need to add experimental elements to your knowledge and experience. Because you create a product, furniture, or space that will be the first of its kind, even if it is similar. For this, you can actually make new discoveries using different materials, as an inventor proposes to. It’s not about doing something different, it’s special for you and for your house. So, consider hiring an architectural service near you that you can rely on.

Why Are Building Regulations Important?


# Building Regulations

Architecture Stratford One of the important segments to think about before developing a building is following the building regulations. Talking about the importance of building regulations, it is one of the best sources to secure safety and plan for the designs and drawings by following the regulations. Moreover, it is also a significant option before submitting the planning application to the authorities. So, they can consider that building regulations are full of consequences.

# Why Building Regulations Are Important?

Emphasizing the significance of building acts, at first, it comes for safety and security. Building regulations implemented in such a way that it can save power and fuel, protect natural beauties, promote large development, and maintain eco-balance. Then, coming to the planning option, building regulations guide for the following steps to put in place regulatory processes and making the drawings for your building.
Also, building regulations needed for any type of new construction works, extension works, or approval from authorities. So, before going to establish any drawings and designs, you should first look at the building regulations and perform according to the instructions.
So, building regulations are essentials in the following factors:

1. Erection Or Extension Of Building:

building regulations cover the important rules for new buildings and extension works.
Moreover, the regulations guide for some alteration to services, underpinning, or changes in using spaces.
In detail, you hardly need the Building Regulations approval for the erection of a detached single-story building which is less than 30m2. Or for any building which is less than 15m2. Till there’s no sleeping accommodation or conservatory extensions with an internal floor area of less than 30m2.

2. Installation Or Replacement Of Central Heating System And Fuel Tanks:

This installation or replacement works related to safety issues, and the person or team that works on it responsible for that. So, the installation or replacement works for gas, oil, or fuel boiler need to follow the building regulations and perform accordingly.
Finally, once the installation or replacement works do, the service provider should also collect the certificate from the authority which will show that the works are in compliance with the regulations.

4. Change Of Building Energy Status:

before the submission of planning permission, you have to follow the instruction for the current energy status and changes in the positioning of the status. Moreover, you have to be careful about the environment, energy-related products, allowable solutions, and so on.
Changes might take place for water heating systems, gas equipment installation, or changes in placing that equipment, fuel system placing, and more. So, for safety and certification purposes, building regulations are important factors to help with.

5. Converting Rooms:

while converting any space to rooms, you have to follow the regulations before you apply for planning permission, and design the area according to get the permission.
Because, at any space, you hardly can develop any type of room in the office space or in your house.

6. Plumbing Works:

plumbing is one of the major works that do while building a new house or repairing the place. For that, you have to keep pace with some of the regulations which are so helpful to get the planning permission.
So, plumbing works, related to boilers, water heaters, unvented hot water systems, range cookers with integral boilers, warm air heaters, and more direct connection to building works that need the attention of the service providers.

7. Electrical Works Or Electrical Equipment Installation:

while placing electrical equipment or operating some electrical works, you must keep in mind the safety and security of the workers, the residents, and all systems.

# Building Regulations Are Only Applicable For Domestics Works And Those Are:

* Works within the dwellings
* Works within the grounds of dwellings or buildings which share their supply with dwellings. For example, it might
   include a pond pump and garden lighting systems
* Works within other buildings or premises that share their supply with dwellings such as sheds, garages, 
   outbuildings, linked shops, and so on
* Works related to the common and shared areas of flats

# When You Do Dot Need Building Regulations?

Here is a list of works that don’t need to follow the building regulations:
1. Maintenance works or minor repairing.
2. Replacement works that are less than 25 percent of an item, like-for-like.
3. More works for power or lighting points and switches (exceptions are for around baths and showers).
4. Alteration works to existing circuits (except around baths and showers).
5. Small replacements such as baths, toilets, basins, or sinks.
6. Boundary or garden walls, fences, and gates.

# Final Words

Building regulations established to keep pace with the ecosystem along with the security of living creatures. To get the approval of planning applications, you should first follow the regulations and design the plans with the help of experts.
Yet, while having all the clearance in your hand, you can start the new building works or other works of existing buildings.

Why Planning Application Must Needed In UK?


# Planning Application

Affluent planning amplifies the grace, keeping this strategy in mind, KPCL Architecture provides standard Planning Application Service, maintaining the hard and fast frameworks, regulated by UK Authority. To establish a design, investors must plan for their desired building structure as without authorization a company cannot wish to start their operation.

# The Benefits Of The Planning Application Are:

  • Smart and accessible process
  • Sequel process and guidelines
  • Affix plans and related scratches
  • Reduce time and money simultaneous
Planning designation settled for all pre-existing uses and buildings by the Town and Country Planning Act 1947, which became effective on 1 July 1948. An application for planning permission required to make to the local planning authority. Talking about the several types of planning permission, it depends on the local authority but KPCL Architecture focuses on the following consents:

# Householder Planning Consent

Deals with alteration or enlargement of single house name extensions, conservatories, loft conversions, dormer windows, Garages, carports, and outbuildings.

1. Full Planning Consent:

Visualises on building works, engineering works, and so on other than householder improvements such as works related to a flat, change in the number of dwellings, changes from residential to commercial, others outside the garden of any property.

2. Legal Development Certificate:

Relates to the establishment of whether-
  • Existing use of lands, or improvements on operations, or tasks in breach of planning terms, follow with law.
  • Offered use of buildings or other lands, or operations invited under land, enforceable by law.

# There Are Several Time Limits For Lawful Development Certificate Such As:

4 Years:

  • This is for building, engineering, mining, or other operations, except for planning permission. this growth becomes unsusceptible from implementation factors four years after the operations significantly completed.
  • This is for changes in the use of building, single dwelling houses. Enforcement actions can no longer exist if unauthorized use has practiced for 4 years.

10 Years:

This is for all other developments. This 10year period circulated from the date the breach of planning control place.

# Prior Notification:

Various invitations for developments involving telecommunications, demolition, agriculture, or forestry. These are subject to a progression whereby minutiae alarmed to the local planning authority former to the maturity placed. Describing our working strategies, at the very beginning, before undertaking an assignment we weigh up the history and context of the site and its adjacent.
We explore your local planning authority and substantiate what planning applications previous neighboring properties have proposed, whether it acknowledged or denied, we still look into it. We also establish where the property based, if it is under a Preservation Area, a listed building, or in a flood risk zone.
These features will affect your planning application and more papers required to accompany the proposal. But, such impediments will discuss with clients appropriate. Following the initial site visit, a site survey and dimension will conduct to assemble all the existing dimensions and a pictorial survey to chronicle the existing site.
Moreover, we practice the preliminary drawings within 7-14 working days ensuring that there are options for the client to consider. We will work with you to make plans that are to your satisfaction and within government legislation (planning and building control).
Furthermore, our professionals are able to create according to the client’s desire as long as it is workable for when submitting the planning application. Once everything finalises and confirmed by the client, the application will submit along with the drawings.
Our consultants at KPCL Architecture agree most applications online through the planning portal. But, there are occasions (usually for larger developments) when it may be necessary to organize a written application with bound drawings and documents.

Detailing the requirements for a planning application, here are different sorts of documents needed for:

# Full Planning Applications:  

This contains all existing drawings of the property (floor plans, elevations, sections),

1. All Proposed Drawings– 

  • Section drawing
  • Detailed drawings
  • Extension drawings
  • Building regulations drawings

Essential Guide For Rear Extension


Essential Guide For Rear Extension

An extension to your house is one of the ways to enlarge the space you already have. Being that you want a larger kitchen and dining space or a downstairs WCs and utility room, sometimes just by adding a couple of metres on the ground floor makes all the difference. Some of these extensions could be done without any planning permissions as long as you stay within the guidelines laid out by the legislation for you. If you are thinking of doing an extension here are some tips on the Permitted Development Rights regulations that you will have to follow that will be reiterated by your design team.

# General Information For Any Extension

  • must not exceed the height of the existing dwelling
  • the extension eaves height must not exceed the existing eaves height, must not be more than 50% of the original garden area, including any previous extensions (sheds are included and other outbuildings must be included when calculating the 50% limit)
  • materials should be of similar appearance to the existing house
  • must not include a veranda, balcony or realised platform

# Single-Storey Rear Extension

  • maximum height of 4 meters
  • must not be more than 3 metres if an attached house and 4 metres if semi-detached beyond the rear wall of the existing house
  • maximum eaves height 3 metres if within 2 metres of the boundary (eaves – a point where the wall meets the roof)

Always check with the council because there may be a restriction on the property. If this is the case Planning permission will be required.

# Two-Storey Rear Extension

  • Must not be more than 3 meters beyond the rear wall of the original house, and must not be within 7 meters of the rear garden boundary
  • Must not be beyond the side of the original house
  • Must be within 2 meters of any boundary
  • Roof pitch of extensions higher than one storey to match that of the existing house, as far as is practicable
  • Any upper-floor window in a wall or roof slope in a side elevation must be obscure glazed and non-opening unless the parts which can be opened are more than 1.7 meters above the floor of the room in which it is installed.

Always check with the council because there may be a restriction on the property. If this is the case Planning permission will be required.

One last thing you should double-check is if there are any manholes or sewers running beneath your house or where you want your extension as these could be some complications.

  • Check is there if any manholes as they need to be 3 meters away otherwise you will need approval from Thames Water to ensure that the particular sewerage network will not be compromised.
  • Can get information from Thames Water to check if there is anything underneath your property.
  • If there is, you can either make sure the extension is not compromising the sewer or you will have to get permissions from Thames Water to relocate the sewer system.
