With a house extension, you are not only adding to your property’s square footage, but you are also improving your home with new architecture complete with modern comforts. If carried out well, it can significantly improve your home value.

Don't move. Extend in style

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.

Side Return – for those who do not want to compromise their rear garden space, this is the perfect option. The strip of land on the side of your Victorian property allows for a Side Return extension. You can either knock through walls to merge the new space into the kitchen or leave it separate and use it as a dining room, office, laundry room, or even a bathroom.

Rear Extension – if a side Return is not possible, or you need more open space, the Rear extension creates space in the back garden. With the right techniques, you can bring in plenty of natural light and create seamless amalgamation to the existing house.

Wraparound Extension – for those who have a side garden and a back garden, this L-shaped design utilises both spaces to maximise extra space. You can create additional rooms plus a kitchen extension.

Multi-storey Extension – your extension doesn’t have to be restricted to one floor. Building upwards saves more garden space, and a rear or side double-storey extension can create an extra room upstairs.

Most extensions can go ahead without planning permission as they are allowed under permitted development. Those who live in a conservation area and listed buildings need local council approval. Multi-storey side extensions and Wraparound extensions almost always need planning permission. You will need Party Wall Agreements, too, as shared boundaries are involved in building work. Permitted Development rules apply only when;

  • Side extensions need to be half the width of the original house.
  • Extensions for detached properties cannot extend more than 8m beyond the rear wall, and 6m if the property is semi-detached or terraced.
  • The maximum height for single-storey side and rear extensions is 4m.
  • Materials used for the extension must be similar in appearance to the materials of the existing house.
  • Height of the ridge or the eaves should not exceed the height of the existing house.
  • Your extension must not be forward of the principal elevation or side elevation when fronting a highway.

Wall of wine

Use the wall in your kitchen/dining area as a wine wall. You can carve out spaces in the wall if thickness permits or design an entire face of the wall to hold wine bottles.

Loft conversion

If you rather have a garden than an extension, build upwards with a loft conversion. It is one of the best ways to save your precious garden space.

A Side Return starts from £35,000

A Rear Extension can start from around £40,000

A Wraparound Extension will cost from £55,000

A Two-storey extension can cost £75,000

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.
