House extensions in Bexleyheath are a great opportunity to increase the living space in your home without going through the cost and inconvenience of moving houses. And with beautiful homes, an easy commute into London, and a thriving commercial area, it’s easy to see why residents would not want to leave their homes in Bexleyheath.

Home extensions also offer homeowners the unique opportunity to design and create a part of their home. This is where Good Design and Build come in. With extensive experience in designing and building bespoke house extensions in Bexleyheath and Kent, we are the ultimate house extension specialists.

Our team works closely with clients throughout the design and build process to ensure that every part of the extension caters to their specifications.

Good Design and Build design home extensions based on the client’s space requirements and the area available. As such, there are a variety of options offered to homeowners with regard to the type of home extension built. This includes:

Rear Extensions

Rear extensions are extremely popular among property owners due to the large area available at the rear of most properties and also due to the possibilities it creates. Rear extensions could be utilised to design kitchen extensions, guest rooms, or even office pods.

Side Return Extensions

Side return extensions run along the area at the side of the property and a portion of the rear area. Side return extensions are often preferred to wraparound extensions as they do not use up too much valuable garden space. This type of extension is perfect for creating indoor-outdoor connections particularly favoured in modern dining rooms.

Multi-storey Extensions

Multi-storey extensions are perfect for adding space and value to a property. Multi-storey extensions add a great deal of square footage to a property with the same roofing and excavation costs as single-storey extensions. These extensions are ideal for creating bedrooms, bathrooms, and offices.

Except for extensions of certain limited sizes, that fall under permitted developments, most home extensions in Bexleyheath require planning permission and building regulations approval.

The process for obtaining building approval takes several weeks and requires a detailed application to be submitted which includes structural diagrams of the proposed home extension.

Fortunately, Good Design and Build oversee the entire process from submitting the necessary documents and diagrams, to coordinating with the local council and securing planning permission.

This ensures that homeowners can be assured that every aspect of the design and build of the home extension complies with building guidelines and regulations.

With its beautiful buildings and inspiring architecture, Bexleyheath is a homeowner’s dream. And when designing home extensions, it is crucial to integrate the beauty of the original structure into the home extension design to amplify its appeal.

Some of the popular extensions in Bexleyheath feature:

Kitchen Extensions

The most favoured style of home extensions, kitchen extensions are perfect for creating a warm and inviting room with a flavour of modernity.

Loft Conversions

Loft conversions are incredibly versatile and can be designed to create additional rooms, offices, or playrooms.

Refurbishments

Even without a conventional extension, the space within a home can be transformed by remodelling and refurbishing the area. The existing space may be altered by creating an open floor plan which brings in both elegance and modernity. And by optimising the natural light that enters, a larger and brighter room is created.

The cost of a home extension in Bexleyheath depends on a number of factors such as:

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

As such, home extensions in Bexleyheath 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.
