House extensions in Lewisham are becoming increasingly popular amongst its residents with the view to upgrade their homes without resorting to moving houses. This is because house extensions offer homeowners the rare opportunity to add space and value to their current homes at a fraction of the cost of relocating.

And Good Design and Build are fast becoming the chosen extension builders for Lewisham and its surrounding areas. With a reputation of high quality, reliability, and transparency, Good Design and Build offer incredible options to homeowners that allow them to design and plan amazing home extensions and refurbishments.

With a wide range of extension types, homeowners in Lewisham can choose between the different styles based on their requirements. Some of the more popular types of home extensions include:

Rear Extensions– Rear extensions are highly sought-after as they create larger spaces and offer a great deal of flexibility. Rear extensions can be utilised to build additional bedrooms, office pods, or even kitchen extensions.

Side Extensions– Side extensions run along the side of a property and give property owners the chance to build brighter living spaces with open floor plans.

Wrap-Around Extensions– Wrap-around extensions are essentially a hybrid of side and rear extensions. They create larger living areas without taking up too much of the garden space.

These house extensions can be designed and aligned according to the property and the homeowner’s requirements to create the ideal extension in Lewisham.

While certain minor renovations and small extensions may fall under permitted developments, that require no planning permission, most house extensions need planning permits to be approved by the local council.

Planning permission and building regulations approval require a detailed application to be made that includes designs of the relevant structures. Luckily, Good Design and Build aim to provide clients with a stress-free experience as they oversee the entire application and approval process.

The cost of a house extension in Lewisham is dependent on several factors including:

  • The extension type
  • The size of the extension
  • The location
  • Groundwork
  • Building materials
  • Fitting and fixtures
  • Specialists’ fees, etc.

As a result, home extensions in Lewisham can range from £35,000 to £140,000.

The team at Good Design and Build offer free consultations and quotations for proposed extensions, and also guarantee complete cost transparency during the build process.

Lewisham is unique in its ability to effortlessly blend its historic architecture with modern purposes. As a result, most extensions in and around Lewisham, aim to find the balance that creates new spaces without altering the structural integrity of the original buildings.

Home extensions that work well within Honor Oak neighbourhoods and create a seamless integration include:

Loft Conversions: Loft conversions are seen as an increasingly affordable option to expand the area within a home. They help create bright, functional rooms from previously vacant spaces and add value to the property.

Kitchen Extensions: Unsurprisingly, kitchen extensions are one of the most popular extension choices for modern homeowners. The ability to recreate the cornerstone of the home into a large and inviting space complete with modern fittings is rightfully seen as a worthy investment.

Multi-storey Extensions: Multi-storey extensions are viewed as an affordable alternative to single-storey extensions. This is because, property owners are essentially able to double the square footage of their extensions while keeping the costs of excavation and roofing unchanged.

  • Design
  • Planning
  • Technical Specifications

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.
