Built around your home and household
The best projects bring light, flow and function to the existing house—not simply more square metres.
We begin with what is not working and what you want everyday life to feel like. From there, we help coordinate the design and technical input, then manage the construction and finishing as one joined-up build.
Extension types
Every extension responds to a different house, plot and brief. We help turn the right concept into a practical, buildable project.

Rework the ground floor with a larger kitchen, dining and family space, a utility, home office or more direct connection to the garden.
Discuss your ideas ↗
Create coordinated space on both floors—for example, an enlarged living area below with additional bedrooms, bathrooms or adaptable rooms above.
Discuss your ideas ↗What could change
We shape the construction around the purpose of the room, the existing house and how the two will work together.
Open up the heart of the home with better circulation, natural light and a stronger connection to the garden.
Create a generous everyday room, a quieter snug or a flexible space that adapts as family life changes.
Add useful first-floor accommodation through a coordinated double-storey design.
Build in the utility room, storage, home office or accessible layout the existing house is missing.

We can help coordinate the measured survey, drawings and design information needed to develop the proposal.
Appropriate structural input is coordinated for foundations, steelwork, openings and other engineered elements.
We support the relevant planning or permitted-development route and help keep information moving between the parties.

Leicestershire single-storey extension
Brooke Construction Services managed the project from the approvals and construction stages through to the completed interior, creating a generous new room connected naturally to the existing house.
The project story
The customer wanted more living space but did not want the extension to feel like a separate addition. From the outset, the project was planned around a wide connection to the original house, a high-quality finish and the practical approvals needed to move confidently into construction.
The challenge
The new room needed to provide meaningful additional living space while remaining visually and functionally connected to the existing ground floor. Planning and Building Control also needed to be coordinated before and throughout the build.
Our approach
BCS worked with the client to ensure the relevant planning and Building Control requirements were in place, then coordinated the foundations, masonry, roof, glazing and internal services. The existing house was opened up so the new room would read as a natural continuation of the living space.
The result
The completed extension provides a versatile new living area with direct garden access and a wide internal connection to the original rooms. The carefully finished space was warmly received by the client and now feels established as part of the home.
