Our favourite fact about Battersea is – since it opened in 1860, Battersea Dogs & Cats Home has been a safe refuge for three million cats and dogs, rescuing 7,000 animals a year, never turning away a homeless creature. Battersea also has Europe’s busiest railway station, although oddly crediting Clapham for its name. Victorian and Edwardian terraced homes feature along the roads in this riverside neighbourhood, and with a mix of state and private schools, it has become an oasis for family life. And, house extensions Battersea reinvent its property scene. When you want to settle more comfortably in a period property, extensions become the answer without having to spend sizable sums on bigger homes or move to less favourable neighbourhoods. No home comes with perfection for everyone. It needs transitioning to the occupants’ way of life with tweaks, modifications, and renewal.

Side Return Extension – The original rear ‘extension’ of period properties has a leftover garden passage along the boundary. A Side Return infills this passage to widen the outrigger of the house. The new volume forms an interior wall on the border. It only utilises a narrow and shaded part of your garden with little effect on the main garden space. This extra space can produce a kitchen extension, a utility room, a boot room, a diner, or even a narrow shower room.

Rear Extension – Extending the floor area at the rear by building onto the back garden creates a Rear Extension. It transports natural hues, sunlight, and warmth of the outdoors to the interior and provides a sweeping space that connects with the garden once opened. Your art studio, piano studio, or even your yoga studio will flourish here.

Wraparound Extension – It combines a Side Return and a Rear Extension to form an L-shaped structure with generous proportions. A Wraparound affords space to create a bedroom along with other living spaces.

Double-storey Extension – A two-storey Side, Rear, or even Wraparound extension can double the space with the same roofing and excavation costs. You gain more versatility to re-arrange the floor plan with this addition.

House extensions are permitted developments that do not need planning permission in most instances. You will require permission if;

  • Your house belongs to a conservation area or is a listed building.
  • New buildings cover more than 50% of the total square footage of the existing house.
  • The exterior of the extension and materials used are not similar in appearance to the existing house.
  • Single-storey extensions are higher than 4m.
  • Extensions are higher than the highest point of the original roof.
  • There are balconies, raised platforms, or verandas featured in your extensions.
  • Single-storey Rear extensions are more than 8m from the original rear wall of a detached house or 6m if the property is semi-detached or terraced.
  • Double-storey extensions extend more than 3m out from the original house and are closer than 7m to the rear boundary.

As most house extensions impact party walls, you need to obtain Party Wall Agreements from neighbours before building work can start. Good Design & Build offers its services to complete this pre-build phase.

Garage Conversion – grandfathered into the original footprint, your idle garage increases livable space without having to go over the limit you are allowed to build with permitted developments.

Mirrored Walls – when a Side Return feels too narrow, use oversized mirrors on the new party wall for a space-enhancing look. Creating small recesses in the wall for miniature décor objects removes the planar quality.

The Fifth Wall – designers consider the ceiling as the fifth wall and often advise you to make it a feature. When the ceiling is low and flattish, you can give it a sense of height and definition with exposed beams. Painting the beams a darker shade, such as black, makes it less sterile.

As an authority on Victorian and 1930s home remodelling, we have acquired expert knowledge in bespoke solutions for space requirements in period properties. Our architectural design process is an artistic and technical process that creates complementary exteriors and soulful interiors. When we build a home extension, we start with professional designs that reflect your style and home. Our emphasis is on functionality and building regulations that make the structure last for generations. We never bind our customers to a project with a long-haul contract; we make sure you are free to change your mind with two separate contracts for design and build stages. All finished products carry insurance-backed warranty and energy certificates. A project manager enables the smooth functioning of the project, and our teams prepare method statements, building control applications, planning applications, Thames Water Build Over Agreement, and assist with Party Wall Agreements.

Extensions can start from £1,000–£2,000m². A single-storey Side Return costs £35K, a Rear extension can cost £40K, and a Wraparound extension costs £55K and more. A double-storey extension can start costing from £75K.

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.
