Choose a West London kitchen extension Specialist

The West London property scene includes some of Britain’s most classic Victorian and Edwardian urban housing. With a design two centuries old, these homes are running out of their potential to accommodate the fast-evolving lifestyle of modern Londoners. Many have chosen to upgrade with kitchen extensions West London. Kitchens are no longer tucked away in poorly-lit rooms; today, they serve multiple purposes than a singular one. In some homes, they are the central attraction, where everyone gravitates to, including guests. We design and build 100% bespoke kitchen extensions for Victorian and 1930s properties to open up spaces and bring in a flood of natural light. Our in-house architects and engineers preserve the integrity of the period architecture while ensuring the new space reflects your needs and tastes.

Don't move. Extend in style

We can save you the hassle that comes with moving not to mention the heavy stamp duty! Adding an extra loft bedroom or enlarging the living kitchen dining space on ground floor is an economical way of transforming your home to suit growing needs. The projects can range from £40-100K depending on your requirements and can be completed within 8-16 weeks.

Not if you have Permitted Development Rights. Kitchen extensions do not need planning permission in most cases, unless;

  • Your property falls within a designated land area
  • You live in a listed home or a building
  • Extensions use more than half the land area of the property.
  • The height of the extensions exceeds at original eaves and the highest part of the original roof.
  • When the extension comes within 2m of the boundary, the height at the eaves exceeds 3m.
  • Single-storey extensions exceed 4m in height.
  • Single-storey Rear extension extends more than 8m (previously 4m) from the property’s original rear wall of a detached house and 6m (previously 3m) of a semi-detached or terraced property.
  • A double-storey addition extends beyond the rear wall by more than 3m or is within 7m of any boundary opposite the rear wall.
  • The roof pitch does not match the existing one.

Most of the time, under Permitted Development Rights, you can build Side and Rear extensions without the need for planning approval. However, you need planning permission if;

Side Return or Infill Extension

19th and early 20th Century terraced and semi-detached houses have an outrigger at the rear. It leaves a narrow strip of the garden adjacent to the house. Infill of this space squares off the floor plan creating a larger kitchen. With a Side Return kitchen extension, there’s no need to sacrifice too much of your garden space.

Rear Extension

By extending your home towards the back garden, you create a more open space that affords plenty of natural light. It is ideal for an open-plan kitchen/dining area with greener views of the garden. You may even find space for a lounge area.

Wraparound Extension

When you need more than just a kitchen extension or a generous-sized kitchen, you can use the Wraparound design to form an L-shaped structure that joins a Side Return with a Rear Extension. The Side Extension can become an extra bathroom or a utility room, and the Rear Extension can become a modern kitchen/dining area.

Double-storey extension

If you want to add a bedroom or even a playroom, use a two-storey extension design. This design can save garden space and reorganise the floor plan to move the kitchen or the dining area upstairs if you like.

High ceilings can make a room feel more spacious and impressive. You can achieve this either by digging down to lower the floor level or by raising roof height. A pitched roof gives you the option to design a vaulted ceiling.

To better integrate the new space with your home, you can add it as an entirely separate building with a traditional or contemporary design – and join the two with a fully glazed walkway. Using structural glazing for the walkway minimises its visual impact and maintains the original character of the building. It is a favoured method that gets you approval.

If you have a characteristic-rich traditional kitchen, bring the rustic look to it with exposed oak beams.  You can combine oak principal rafters, collar, tie beams, braces, ridge, and purlins with softwood rafters that are invisible behind plasterboard and insulation.

Do not neglect the existing house by only focussing on the kitchen extension. Introduce more light into the main house using glazed windows and doors, roof lights, a roof lantern, or a clerestory.

The size, the design features, and building works determine the costs. The basic home extensions in southwest London start from;

£35,000 for Side Return Extensions

£40,000 for Rear Extensions

£55,000 for Wraparound Extensions

£75,000 for Double-storey extensions

How we deliver projects

Our process is simple and divided into two distinct phases with separate contracts: Design and Build. As a client you only commit to one phase at a time depending on what stage of the process you are in. Each phase consists of three stages as described below.

1. Design

This is the kick-off point for your project. We carry out a complete architectural measured survey of the property. This allows us to create accurate CAD design drawings. This is followed by a design meeting to start discussing your ideas in more detail.

2. Planning

At this stage we finalise the designs with you and start preparing planning applications as needed. We place a high priority on ensuring that plans, designs and schedules are all based on a thorough and detailed understanding of planning guidelines. We co-ordinate with local authorities until the decision is made, and the planning approval is secured.

3. Technical

Once the planning consent is secured, we translate the design drawings into more detailed technical drawings for the purposes of building control and construction. This also includes specifications and structural calculations. At this stage, we will also submit to you our ‘no obligation’ quote for the build phase.

4. Pre-build

90% of our clients decide to stick with us after the design phase is completed. Once the build contract is signed, we kick off the process by making sure all the pre-build processes are complete. These include assistance with party wall agreements, Thames Water build over agreement, submitting building control application, and preparing method statements etc as needed. This stage ends with a pre-start meeting with your foreman before the actual build begins.

5. Build

One of our foremen will be dedicated to your project and will be on-site to manage everyday works. Our project managers will be overseeing the works to make sure they are completed to high standards, within your budget and on time. Throughout the process we will keep you updated with the progress and coordinate the works with third parties such as kitchen or flooring suppliers. We will also advise and guide you to choose any suppliers if needed.

6. Handover

As the build draws to finish, we will help to iron out any ‘snags’ to make sure everything is completed to your satisfaction. We will put together all necessary certificates such as gas, electricity and building control completion along with warranties for glazing, boiler etc. At the final completion meeting, we will hand you these documents, together with the keys to your house. Needless to say, you can contact us any time after this, if you want us to look at something.
