With rising property prices, increasing stamp duties, and cramped and uncomfortable living spaces, homeowners often find themselves in a no-win situation.

Fortunately, home extensions offer the perfect answer to this seemingly impossible dilemma. How?

Because home extensions provide the simple, yet elegant, solution of avoiding the expense and inconvenience of moving homes. And the versatility and adaptability of home extension designs enable homeowners to create the ideal space within their homes that not only adds more living space, but also upgrades their homes to create the ultimate extension.

A home extension is an ideal opportunity for homeowners to upgrade and elevate their properties while overcoming space deficits. Simply put, house extensions help homeowners to add space and value to their homes through innovative designs, and at a fraction of the cost of moving houses.

House extensions in Surbiton are broadly divided into the following types based on the area of the property on which they are built:

Rear extensions-

These extensions are built on the rear of a property and are incredibly popular as the space allows a great deal of versatility in their design and use. Rear extensions are most-often utilised to create kitchen extensions, guest rooms, playrooms, or even office pods.

Wrap around extensions-

Wrap around extensions are essentially a combination of rear and side extensions to create an L-shaped structure that ‘wraps’ around the property. These extensions add substantial width and depth, and therefore can be used to create multiple rooms, larger kitchen-diners, or even open floor layouts.

Side return extensions-

Side return extensions utilise the area that runs along the side of a property as well as a portion of the rear area. These extensions are extremely popular among homeowners as they do not take up too much valuable garden space, and are perfect for creating the beautiful indoor-outdoor connections that add ample natural light and ventilation.

Multi-storey extensions-

Though more complex than single storey extensions, double storey extensions add incredible floor space and value to a property. And because the roofing and excavation costs remain largely unchanged, while the area of the extension is essentially doubled, multi-storey extensions are considered to be extremely cost-effective.

The requirement for planning permission for a house extension depends largely on the design and dimensions of the build. More often than not, if the extension falls under permitted developments, planning permission is not required.

However, permitted developments have specific criteria and limitations which must be adhered to, such as:

  • Extensions must not take up more than half the land around the original house
  • Extensions cannot be higher than the highest part of the existing roof
  • Materials used for the exterior of the extension must be similar in appearance to that on the exterior of the original house
  • Side extensions can only be single-storied and cannot exceed more than half the width of the original house

Moreover, extensions built on properties listed in conservation areas will need planning permission irrespective of their design. The planning portal provides homeowners with comprehensive information regarding any requirements or specifications for their proposed extensions.

Planning permission can take up to 8 weeks for approval and requires a detailed application including structural diagrams of the proposed extension. In addition to planning permission, building regulations approval and party wall agreements must also be considered to ensure that the proposed extension meets the building guidelines and standards.

Good Design and Build oversee this entire process for our clients. From the primary survey of the location and the design of the proposed extension, to coordinating with the local council and securing the requisite approvals. This allows homeowners to experience the extension process stress-free.

With multiple designs and styles for home extensions available, creating the perfect extension that combines seamlessly with the existing structure, is entirely possible. Some of the most popular home extension styles that feature in Surbiton properties include:

Kitchen extensions-

Kitchen extensions help transform small, dark kitchen-diners into warm, spacious and inviting spaces, ideal for hosting intimate dinners or big celebrations. With the installation of the latest fittings, kitchen extensions are the perfect addition to complete your modern home.

Loft conversions-

Loft conversions help convert awkward and often ill-used loft spaces into valuable and functional living space. Loft conversions are perfect for creating additional bedrooms, bathrooms, or even study nooks.

Garage conversions-

Garage conversions are a simple, but effective, approach to transform unused spaces within your home and optimise its potential. The garage may be converted to a separate additional room, office, or study, or may even be integrated into the floor plan of the interior to create larger kitchen or dining areas.

Refurbishments-

Not every home requires an extensive extension to transform the existing space and create larger and brighter living spaces. An innovative approach to a classic renovation that changes the layout, creates an open floor plan, and optimises the natural light can have a dramatic effect and could help you to create the ideal space that is perfect for your home.

The cost of a home extension in Surbiton may range from £35,000 to £135,000. This is because the cost of an extension is dependent on a large number of factors including:

  • The size of the extension
  • The design/ complexity of the extension
  • Location
  • Groundwork
  • Building materials
  • Fittings and fixtures
  • Specialists’ fees, etc.

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.
