Extensions
Professionally Built Home Extensions in London

If your home no longer gives you the space you need, moving is not always the answer. A well-designed extension can give you more room, improve the way your home works and add long-term value to your property.
At Golbik GBS, we build home extensions from the initial planning and preparation through to the final finish, coordinating the construction process and the trades involved throughout.
Whether you want a larger kitchen, an additional bedroom, more living space or better access to your garden, we can help transform your existing property around the way you live.
Types of Extensions We Build
We work on a range of residential extension projects, including:
- Single-storey rear extensions
- Side-return extensions
- Double-storey extensions
- Wrap-around extensions
- Loft and roof extensions
- Garage conversions
- Open-plan kitchen and living extensions
- Orangeries and glazed extensions
Every property is different, so we assess your existing space and discuss the most suitable approach for your home, budget and requirements.
From Planning to Completion
Before construction begins, we carry out a detailed consultation and survey to understand the project and identify the work involved.
Where planning permission or building regulations approval is required, we can work alongside the relevant professionals to help ensure the construction process is properly coordinated.
Once construction starts, our team manages the different stages of the build, including foundations, structural work, brickwork, roofing, insulation, plastering, electrics, plumbing and internal finishing.
By coordinating the different trades involved, we provide you with a straightforward point of contact throughout the project.
