Homes in the beautiful Borough of Waltham Forest offer its residents the perfect balance between the quiet country life and the bustle of the city. With open, green spaces, a busy town centre, and outdoor activities that offer both relaxation and rejuvenation, it is viewed as the ideal place in which to raise a family. It is therefore no surprise that most families and homeowners choose to extend their homes rather than incur the cost and inconvenience of moving houses, when faced with a lack of living space.

Home extensions in Waltham Forest are the ideal opportunity to create extra space in your home, increase its value, and add a unique design element of your own.

But in order to achieve the perfect house extension, it is imperative that you begin this process with a clear idea of the extension you want to create, and choose the best extension specialists for this crucial investment.

A home extension is the ideal opportunity for homeowners to expand and upsize their homes at a fraction of the cost of moving houses. It allows homeowners to design and create beautiful spaces within their properties that are the perfect additions to combat cramped and outdated rooms.

Best of all? Home extensions can increase the value of a property by up to 20%!

House extensions are categorised into different types based on the area of the property on which they are constructed. As such, home extensions in Waltham Forest include:

Rear extensions

Built on the rear of a property, these extensions offer incredible versatility in their design and use. Rear extensions are generally utilised to create kitchen extensions, guest rooms, or even office pods and playrooms.

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. They are ideal for creating beautiful indoor-outdoor connections that bring in abundant light and ventilation to a home.

Wrap around extensions

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

Multi-storey extensions

Two storey extensions, though more complex than single storey extensions, add incredible floor space to a property. They are also extremely cost-effective as they effectively double the square footage of the extension without doubling the roofing and excavation costs. Multi-storey extensions help create multiple rooms and bathrooms within the property.

Not necessarily.

The requirement for planning permission is largely dependent on the design of the proposed extension. Extensions that fall under permitted developments do not need planning permission. However, to be categorised as a permitted development, the proposed extension must meet specific size limitations.

Also, properties that are listed in conservation areas will require planning permission irrespective of the extension size.

The planning portal provides homeowners with a comprehensive understanding of what is allowed, and which extensions will require planning permission.

If planning permission is required, a detailed application including structural diagrams of the proposed extension needs to be submitted for approval. This process can take up to eight weeks based on the complexity of the extension.

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

Home extensions come in an array of styles and designs. Many properties in Waltham Forest feature extensions that are a combination of elegance, functionality, and modernity. These include:

Kitchen extensions

A classic home extension request that transforms small and dark kitchen-diners into warm and inviting spaces perfect for hosting dinners and celebrations. With the installation of the latest fittings, kitchen extensions are ideally suited for modern homes.

Loft conversions

A wonderful way to maximise the loft space within a home, loft conversions offer incredible versatility to homeowners in how they are designed and used. They are ideal for creating additional bedrooms, offices or playrooms.

Refurbishments

Even without a typical extension, the existing space within a room can be transformed and recreated through refurbishments. Changing the layout, creating open floor plans and optimising the natural light that enters through the addition of well-placed windows, helps to create larger and brighter living spaces.

Home extensions in Waltham Forest can cost anywhere between £30,000 to £130,000. This is because the cost of a home extension depends on a number of factors such as:

  • The size of the extension
  • The type/ complexity of the extension
  • Location
  • Groundwork
  • Building materials
  • Fittings and fixtures
  • Specialists’ fees

It is therefore a good idea to plan a budget that takes these factors into consideration in order to create the best possible home extension.

A house extension is an incredible opportunity to add space and value to your home provided it is done right. To create the perfect extension that proves worthy of the investment, it is imperative that the best home extension specialists are consulted.

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.
