The winning formula for house elegance

Heart of the Home is getting makeovers all across the country, but which transformation makes the difference? Kitchen-central home life is increasingly becoming dominant. A family spends more and more hours in the kitchen, making it an integral part of the house than ever before. The extra living space is essential to enjoy this lifestyle transformation. Your property in Wimbledon will see itself rising in the upmarket ladder with added square footage. These kitchen extensions Wimbledon are game-changers for any southwest London home.

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.

Single Storey Extensions – take place on the ground floor and basement if there is any.

Rear Extension

Attached to the rear end of the home, this type of extension can house an open plan kitchen combining dining and living areas. This space can extend to the garden via sliding doors.

Side Return Extension

Specifically beneficial for Victorian and Edwardian properties with alleyways on the side, this home extension adds 3m to the kitchen width. Rooflights and glazed ceilings can brighten up the room.

Wrap Around Extension

Both a Side extension and Rear extension come together to form this L shaped addition. It maximises the ground floor potential to create a roomy kitchen, dining area, and sitting area.

Double Storey Extension

With two levels at your disposal, you can create the perfect kitchen-dining area ensemble downstairs and a master bedroom, en suite, or children’s room upstairs. You can build this on to the side or the back of the property.

Extensions in Wimbledon fall under permitted development rights and do not require planning permission as long as you follow the guidelines. These rights, however, are restricted on designated land and for listed buildings. For all extensions, the following conditions apply;

  • Only half the land area owned by the property should have extensions.
  • No extension should be higher than the highest part of the house roof.
  • There are no balconies, raised platforms, and verandas.
  • The structure does not extend towards the highway.
  • The existing roof structure does not go through any alterations.
  • The exterior doesn’t feature cladding.

We are extension specialists with expertise in Victorian and 1930s house extensions. Our architects draw up bespoke designs that reflect your life and its needs. With us, you don’t have to commit to the extension project straightaway. We prepare two separate contracts for the Design and Build phases, so you can opt-out at either stage if you are not happy. Good Design & Build submits applications on your behalf when planning permission becomes a requirement.

House extensions can cost from £1,200 per square metre to £2,500 per square metre. A Side Return Extension is the most affordable and can cost from £35,000. The cost for a Rear Extension starts around £40,000. A Wrap Around Extension can begin from £55,000, and a Double Storey Extension costs £75,000 upwards.

Transform your home stress-free with London’s most design-forward kitchen extension company.

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.
