House Extensions

A house extension adds space to your home at the side, the rear or over an existing structure, such as a bigger kitchen, an extra bedroom or a home office. We build extensions for homeowners and landlords, working from your plans or helping you establish what professional input the project needs.

House Extensions
FAQ & Guidance

Frequently Asked Questions

Common questions about our house extensions service.

Do I need planning permission for an extension?

It depends on the size, height and position of the extension, the type of property and where it is. Some extensions fall under permitted development, while others need planning permission. Building Regulations approval is a separate requirement that usually applies either way, so check with your local planning authority or an architect before work starts.

How much does a house extension cost?

The cost depends on the size and type of extension, ground conditions and foundations, the structure and roof design, the specification of windows, kitchens or bathrooms, site access and any professional fees. We quote once the design and scope are clear enough to price accurately.

Can I live at home while the extension is built?

Often, yes. Much of the work happens outside the existing house until the new space is opened up. We plan how access, dust and noise are managed, and tell you which stages are likely to be more disruptive.

Do I need drawings before asking for a quote?

Drawings help us price accurately, so upload them if you have them. If you are at an earlier stage, tell us what you want to achieve and we can explain what drawings or professional input the project is likely to need.
