House Extension FAQs

How much does a house extension cost in High Wycombe or Oxford?

Costs vary depending on the size, type (e.g. single storey or double storey), and specifications of your extension. On average, you can expect a single storey extension to start from £1,500 per square metre. We offer free consultations and quotes tailored to your project.

Do I need planning permission for a house extension?

Not always. Many house extensions fall under permitted development rights, especially single storey rear extensions. However, double storey or wrap around extensions often require planning permission. We can advise and assist you through the planning process.

How long does a typical house extension take to build?

Timelines vary depending on complexity, but most single storey extensions take between 10–14 weeks. Double storey or larger builds may take longer. We provide a clear project timeline before we begin and keep you updated throughout.

Can you match the extension materials to my existing home?

Absolutely. We take great care to ensure that your extension blends seamlessly with your home, using materials that match the brickwork, windows, roof tiles and more.

Will I need to move out during the work?

Not necessarily. Most of our clients remain in their homes during construction. We work to minimise disruption and keep you informed at every stage.
