Frequently Asked Questions
1. Do I need planning permission for a house extension in Oxford?
Not every house extension requires planning permission. Many single storey and some rear extensions may fall under permitted development rights, depending on the size of the extension and your property. If planning permission is required, we can work alongside your architect or structural designer to ensure the project is built in accordance with the approved plans.
2. How long does it take to build a house extension?
The construction time depends on the size and complexity of the project. A typical single storey extension may take around 10–16 weeks to build, while larger double storey or wrap around extensions generally take longer. We’ll provide a realistic programme before work begins and keep you updated throughout the build.
3. Do you carry out the structural work?
Yes. We undertake all structural construction, including foundations, drainage, brickwork, steel beam (RSJ) installation, roofing and structural alterations required to complete your extension safely and to a high standard.
4. Can you build from my architect's drawings?
Yes. We regularly work from architectural drawings and structural calculations provided by your architect or structural designer. Our role is to deliver the construction in line with the approved plans and building regulations.
