More space, without the guesswork
An extension is a big investment, so you want to see what you're getting before you commit. We measure your home accurately with a LiDAR survey, then design the extension in 3D and colour so you can see how it looks inside and out. Once you're happy, we prepare the planning drawings and submit the application.
Designed with planning in mind
The extensions that get approved first time are usually the ones designed with the council's guidance from the start. We consider:
- How the extension relates to the original house in scale, roof form and materials
- Neighbours' light, privacy and outlook
- Garden size and parking
- Conservation areas, listed buildings and other local constraints
- Whether the work could be done under permitted development instead
From planning to building
Once planning is approved, we can prepare the building regulations drawings for the same project, so your builder has everything needed to price and start the work.
