Very good services,Done on time & really professional staffs. Thanks for helping me to build my loft which creates an additional beautiful bedroom with Juliet balcony.

Zade Jakson

Good service at a good price,I was happy to deal with Fawad and KPCL for my kitchen extension application, they dealt with everything (calculation/council application/thames water application) and the process was straight forward and hassle free. They provided an initial quote that was competitive and completed each steps of the process in a good timeframe.


Nothing but praise from me for KPCL. Loft conversions were a wholly unknown world to me, but Fahad managed to make it seem simple and straightforward and just that bit less scary, as well as ensuring all the right bits of paper were in the right place at the right time.

Lina Nicolli

Fahad and Val were very professional and knowledgeable whilst helping to design my ‘L’ shaped loft conversion. Compared to previous experiences working with KPCL was a breeze. From my initial consultation they understood straight away what was needed from the project, produced detailed drawings quickly and dealt with my local planning authority with minimum fuss. I will definitely be returning to KPCL for my next project!

Lester De Silva

High quality and excellent value service, Fahad was particularly helpful guiding us through the process from concept design to approvals for our loft conversion project. Would definitely recommend.

Keystone Property Consultants Limited is one of the growing architecture firms in London who started their business in 2012, and till now they are acting in full swing. Although the architecture office of this group is situated in Stratford, they cover a huge area of London for architecture service.

In London, small architecture firms can hardly provide 3-4 architecture-related works with enough manpower. Talking about the services of Keystone Property Consultants Limited, they provide nearly all the services unlike the architectural designers in London. The services they are specialized in are:


We research about your local planning authority and corroborate what planning applications previous neighboring properties have proposed, whether it was accepted or refused we still look into it. We prepare the initial drawings within 7-14 working days ensuring that there are options for the client to consider. Once planning permission has been granted, the CAD drawings can be re-configured and adjusted to provide building regulation drawings and detailed/technical drawings for building control approval – services which KPCL Architecture can additionally provide.


We can produce a full drawing and specification package for building regulation approval of your project. The building regulation drawings can also be provided to a builder so you can ensure that the construction work is progressing correctly. From the simplest of work to the most complicated large scale projects, all building work will need to pass these standards. KPCL has the knowledge and experience to make this part of your project as easy and less disturbing as possible.


As the structural calculation in important for other services such as loft conversion, wall removal or opening, foundations, and more, KPCL is doing this service by themselves to get the reliable result for further works.


Floor plan is one the vital part of planning permission. If the plan is not efficient and not planned within the rules and regulations, the legislation might reject the plan and we fail to develop your dream house. KPCL is an expert in the planning application and has clear knowledge about what types of applications get rejected, so they make the plans according to it.

On the other hand, for a lease plan, it is important to label the area of a lease, whether it is a commercial space or personal property. As it is supplied to the solicitor, it must be prepared under laws and covered under the regulations. KPCL is also there to help you with this.


KPCL team research and select to take on projects which we feel are feasible and have a strong possibility of achieving good feedback. In most cases, the planning authority can be constructive in giving applicants the opportunity to amend the application before it is decided, and we can help by speaking with the officers to obtain the best advice to get the planning approved.


The renovation process needs a lot of things to bring under consideration from existing building condition to the surrounding environment. KPCL team and affiliates can guide you through the whole process because they are operating for more than 10 years.


KPCL can help you with a team of specialized interior designers who can help you turn all those great ideas that you have into an organized plan. We can also provide with 3D renders as well as 2D. To produce architectural or interior render it, requires a lot of creativity and time to complete one walkthrough animation.

KPCL staff makes every effort to satisfy the clients with their excellence of work, receptiveness, and authentic concern for their achievement. The team is dedicated to the clients’ project execution right from the initiation through to the project completion stage.
