Frequently Asked Questions About House Extension

1. How long does a house extension take to complete?

The timeline depends on the type of extension and its complexity. For example, a single storey extension may take less time than a double storey or loft conversion. We provide a detailed timeline tailored to your specific project during the planning phase.

2. Do I need planning permission for an extension?

Some extensions may require planning permission, while others fall under permitted development. We handle all the necessary applications and ensure compliance with local regulations.

3. What’s the difference between a single-storey and a double-storey extension?

A single-storey extension adds ground-level space, while a double-storey extension adds both ground and upper-level space, providing more room for larger households or multifunctional areas.

4. Can you help with ideas for maximising small spaces?

Absolutely! We specialise in creating bespoke designs that make the most of every inch of available space, regardless of size.

5. What is the typical cost range for an extension?

Costs vary based on the type of extension, materials, and location. After an initial consultation, we can provide a detailed estimate based on your specific requirements.
