Frequently Asked Questions
What You Need To Know
Do I need planning permission for a house extension?
Not all house extensions require planning permission, as many fall under permitted development rights. However, this depends on the size, location, and type of extension. We can advise whether planning permission is needed for your house extension and help guide you through the process.
How long does it take to build a house extension?
The timeframe for a house extension varies depending on the size and complexity of the project. On average, most house extensions take between 8 and 16 weeks to complete, once work begins.
How much does a house extension cost in the UK?
The cost of a house extension depends on factors such as size, design, materials, and location. A site visit and detailed quote will provide an accurate price based on your specific requirements.
Will a house extension add value to my property?
Yes, a professionally built house extension can significantly increase your property’s value while adding usable living space. Extensions such as kitchen extensions and open-plan living areas are especially popular with buyers.
Will you manage the entire house extension project?
Yes, we offer a full design-and-build service for house extensions, managing everything from planning and groundwork to construction and final finishes for a smooth, stress-free experience.
