# Do You Need Planning Permission For Kitchen Extension?

Small extensions might not need planning permissions as long as they are under the guidelines of the permitted development. Larger extensions, or addition to a flat, always need permission. As well as listed buildings always need consent, whether the works permitted development.

In order to do any extension without planning permission, the following conditions must be fulfilled.

  • The area of the extension can not exceed 50% of the total land covered by the property, except for the existing building.
  • The limit for single-storey rear extension can not be more than 4 meters.

  • Multi-storey rear extension rear wall can not outdo the original rear wall by more than 3 meters.
  • The distance between two storey building and the rear wall boundary must be 7 meters or more.
  • For extension at any conserved area like public parks or places of natural beauty, planning permission is required.
  • For any type of side extension, planning permission is a must.

# Can I Draw My Own Plans For An Extension?

For any of your architectural advancements, you surely need a plan and diagram. This diagram should be accurate in accordance with your plans.

You can draw your own plans for an extension, but only if you have enough experience in this regard. You need to consider the caliber of the project and measure your construction accordingly. Moreover, you need to have enough knowledge of whether you will require planning permission or not. In case if you need to get permission, the drawings should be accurately scaled as given by the council.

Further, rough sketches won’t just do for your extensions. You need to have CAD expertise to pull off the finest drawing.

If your drawing is once rejected, you need to repeat the whole process all over again! This would cost you both extra money and time. Therefore, it is wise to let the experts handle the hard work of designing a kitchen extension for you.

# Types Of Extension For Your Kitchen

The type of extension your kitchen extension falls under is a crucial factor to consider. The types are discussed below.

1. Combining Adjoining Rooms :

Converting two rooms into an open-plan kitchen design allows the family and guests to perform many functions together in the same space. This is great if you want to combine a kitchen-living room or kitchen-dining room. In this way, you are able to entertain or even keep an eye on the children while cooking in the kitchen. Most kitchens are in the rear so with an open plan there is potential for allowing more natural light into space by adding a bi-folding door to the garden.

There would be an uninterrupted line of sight where you can still see everything while other people are performing other actives such as watching TV or kids playing. The open plan gives you a larger feel to space. As well the kitchen becomes a focal point of the house as you walk in the property. A structural engineer will need to ensure that the wall that is being removed isn’t a load-bearing wall.

In the case, the wall is a load-bearing wall your structural engineer will need to do the additional calculation for the type of RSJ (rolled steel joist). This will be acting as a supporting beam. However, this will be an extra cost and might involve more disruption to the construction of your open plan kitchen.

2. Conservatory:

A conservatory is an extra room to the house that is in the rear of the property on the ground floor looking out at the garden. The floor area for a conservatory doesn’t exceed 30 square metres of floor area and separated from the building it attached to. Also, it has an independent heating system from the main building. By adding a conservatory could add value to your property to potential buyers.

Especially if you have a south-facing garden, a potential buyer wouldn’t mind paying more for the house if there is already a conservatory instead of undertaking the project themselves. A conservatory can use as a new room to the house or an extension of an existing room, where it brings a lot of natural light as the conservatory would be completely glazed. Conservatory kitchen extensions are very desirable for all the reasons.

3. Rear Extension:

If you have enough room in your garden extending out is a good option. But it does cost a lot more than the other option for extending your kitchen. But having a kitchen rear extension means you can create your own dream kitchen and how you want the layout to be. Depending on the layout of your property there are different types of rear extensions:

4. Single Storey Extension:

Single story extensions are simple extensions built onto a part of the house whereby one side (or more) of the extension attached to the property on the ground floor at the back of the property in the garden area. This is a great way of adding more space to your existing kitchen. By having more room there could be a dining space, extra workspace, or a bigger area for appliances. The design of the roof should work with the all look of your property, and if not it will affect your neighbors sunlight.

5. Double Storey Extension:

Two stories or multi-story extension is like a single story extension built to a part of the existing building. Although, the chances for neighbors to appeal against your extension are greater as it might be overlooking or blocking some of their natural light. We would strongly tell you that you get a letter from the planning department before you start your construction. Also, talk to your neighbor in case they do have some issues about it so they don’t feel left out. But, two-storey extensions to your home give you that extra space on the ground floor and on the first floor as it could be a more bedroom or an en suite for the master bedroom. This extension will also increase the value of your property if you decide to sell in the future.

6. Side Return Extension

Side return extensions are a common choice for a Victorian or Edwardian era house. These houses usually have a gap at the side of the house, which is rarely used and called dead space. By adding a side return you are not taking anything from your garden space but are adding to the kitchen space that you already have, by adding skylights this will bring more light into the area and be utilizing the dead space. This is the smallest type of rear extension which means smaller jobs and cheaper than the other extensions. Thus, it is perfect if you have such a construction.

7. Wrap-Around Extension:

The wrap-around extension is the biggest out of the kitchen extension ideas. It is so as it requires more work but they do add a larger space to the property on the ground floor. A wrap-around extension is a side return and rear extension together in an L shaped space. There are two options for a roof it could have a slope or be flat. This does give you the opportunity to completely open up the kitchen and have as much natural light coming from the top as well as having a full-length view of your garden with bi-folding doors. You could even add a utility room or a downstairs WC or walk-in storage and use all the space available.

4. The U-Shape kitchen layout is usually fitted for a medium kitchen and it can have the three main necessities (fridge freezer, sink, and cooker) all on their own side in the kitchen. This also gives you an excellent triangle working area.

5. The kitchen island is a great way of breaking between the space and can use a breakfast bar.  Moreover, extra storage, more worktops, and another area for a great sink or a cooker can be placed separately from the wall.

# Extension Price

All the above extensions are different prices but as a general cost should estimate from £1,260. Further, expect to spend an additional £2,000 for an extension that is plastered finish giving a cost of £25-50,000 for the footprint of around 25 square metres­.  If your builder takes payment depending on the area, be certain to pay an average of £80 per square meter for low-cost extensions.
