Wandsworth in South West London, is one of the most prestigious boroughs in London, boasting of beautiful neighbourhoods, a vibrant culture, and excellent amenities. The houses here are prized by their owners and valued by the council.

However, homeowners still face the mundane issues of cramped living spaces and an increasing need for more functional living space. To combat this, property owners in Wandsworth often opt for home extensions to increase the floor space of their homes rather than give up their enviable addresses.

Home extensions in Wandsworth must be carefully considered so that the extension seamlessly integrates with the original house to create a beautiful and elegant structure. To help achieve this, the home extensions must be entrusted to reputed professionals and extension specialists.

A house extension is a quick and simple solution by which homeowners can upgrade and redesign their homes to create more living space, while also increasing the value of their properties.

The ideal home extension flawlessly combines contemporary design and functionality, with the beauty and elegance of the original structure, to create the perfect blend of comfort and splendour.

Home extensions are generally classified into different types based on the area of the property on which they are built. As such, popular extensions in Wandsworth include:

Rear extensions

Built on the rear of a property, the versatility of rear extensions, make them a popular choice among homeowners. Rear extensions can be used to create kitchen extensions, guest rooms, play rooms, or office pods.

Wrap around extensions

A combination of side and rear extensions that create an L-shaped structure, wrap around extensions add incredible width and depth to a property. As a result, these extensions are useful in creating multiple rooms, lager kitchen-diners, or even open floor plans.

Side return extensions

These extensions utilise the area that runs along the side of a property, along with a portion of the rear. Side return extensions are ideal for creating beautiful indoor-outdoor connections that add an abundance of natural light and ventilation to a home.

Multi storey extensions

Multi storey extensions are a cost-effective solution by which you can add incredible floor space to a home. This is because, these extensions essentially double the area of the extension without doubling the roofing and excavation costs. Double storey extensions are perfect for creating additional bedrooms, bathrooms, or even high-ceilinged living spaces to a home.

Most home extensions constructed in Wandsworth will not require planning permission provided that they meet the specific criteria of permitted developments. These criteria and specifications include:

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

However, extensions that do not fall under permitted developments, and those constructed on properties listed in conservation areas, will require planning permission.

Applications for planning permission require detailed diagrams of the proposed extension and may take up to eight weeks to process.

In addition to planning permission, building regulations approval and party wall agreements also need to be considered. These ensure that the proposed build meets the building guidelines and standards.

Good Design and Build oversees this entire process for our clients. From surveying the location, submitting a comprehensive application which includes structural diagrams and calculations, coordinating with the local authority, and securing the requisite planning permission and necessary approvals.

Wandsworth boasts of highly-valued residences full of history and charm. As such, when designing home extensions, it is imperative to take into account how the new extension integrates with the original structure.

Some classically good designs for extensions in Wandsworth include:

Kitchen extensions

One the most-requested home extension designs, kitchen extensions add incredible value to a property. They are also ideal for creating warm, bright, and spacious kitchen and dining areas that are perfect for modern homes.

Loft conversions

A perfect way to utilise awkward loft spaces and convert them to beautiful rooms that add value to your property. Loft conversions help create additional bedrooms, home offices, or even playrooms.

Refurbishments

The existing space can be transformed even if you do not wish to go ahead with an extension. Refurbishments offer homeowners the chance to remodel their homes and create bright, open spaces suited to their needs and lifestyle. This may be done by re-designing the floor plan, maximising the natural light that enters through well-placed windows, and subtle interior design.

The cost of a home extension in Wandsworth is dependent on a number of factors including:

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

As a result, the cost of a house extension in Wandsworth can range from £35,000 to £140,000.

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.
