Because when you live in a great area and have a home you are proud to call your own, the idea of moving elsewhere simply due to lack of adequate living space seems inconceivable. This is the reason why home extensions in Bromley are in such demand.

And that is where Good Design and Build comes in. With unique designs centred around your needs, our team can help transform your home in Bromley into beautiful and modern masterpieces. Our in-depth knowledge of the Bromley and West Wickham areas, combined with our passion, and expertise, make Good Design and Build exceptionally suited for the task.

After deciding on a house extension specialist, it is usually a good idea to understand the different types of house extension options. Depending on the space required and the space available, home extensions may consist of:

Rear Extensions– Invariably the most popular type of extension, rear extensions provide homeowners with a variety of possibilities in how to best utilise the area available at the rear of the property. These can include kitchen extensions, office pods, or additional bedrooms.

Side Extensions– Side extensions, as the name suggests, utilise the area along the side of a property. This type of extension is particularly useful to increase the space within living areas or create open floor plans, bringing a combination of modernity and elegance into the home.

Wrap-Around Extensions– Wrap-around extensions are essentially a combination of rear and side extensions and work beautifully to convert limited spaces into larger and brighter functional rooms.

Multi-storey Extensions– These are ideal for homeowners looking to significantly expand within a limited budget. With roofing and excavation costs remaining unchanged, and square footage doubling, multi-storey extensions help the transformation of homes into spacious residences.

When looking to renovate or refurbish, homeowners in Bromley must also consider the permits and building approvals required to carry out the home extensions. According to new regulations, when extensions are done under specific size limitations, no planning permission is required.

However, in most cases, planning permission and building approval is a requisite. The cost and time taken for the permit to be granted depends on the size or complexity of the extension.

Luckily, our team at Good Design and Build, oversee the entire process of obtaining planning permission for house extensions in Bromley. From liaising with the local planning authority in Bromley and the council, submission of the relevant documents, and securing the approval. Leaving our clients to enjoy the process without the stress.

Depending on the needs of our clients, the Good Design and Build team can convert any available but previously inaccessible space into beautiful designs that suit the original framework of the house while adding value to it. Some popular home extensions in Bromley feature:

Loft Conversions– These are ideal for growing families as loft conversions can help create bigger and brighter rooms. Loft conversions are also of many types, so though they may seem daunting to undertake, the result is invariably worth it.

Kitchen Extensions- A homeowner’s dream is a large, bright, and airy kitchen, and kitchen extensions provide exactly that. Kitchen extensions also add great value to the home and can be constructed perfectly suited to meet the modern clients’ requirements.

Refurbishments- If the space available is incompatible for a home extension, the property can still be transformed and upgraded by a complete remodelling. Changing the layout, addition of skylights, and refitting the interiors can contribute to the creation of modern and open areas that provide greater functional, living space within the home.

The cost of a home extension in Bromley is largely dependent on the size and design of the extension. Other costs to be considered include building materials, fittings and fixtures, specialists’ fees, etc.

Home extensions in Bromley can therefore range from £40,000 to £150,000. Good Design and Build provide free consultations and quotations to ensure that clients have the benefit of all the information during the extension process.

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.
