Do I need planning permission for a house extension?
Many single storey extensions fall under permitted development and don’t require planning permission, though this depends on the size, position, and your property type. Larger or double storey extensions are more likely to need permission. We can advise based on your specific situation.
What types of extension are there?
Common types include single storey rear extensions, side return extensions, wrap around extensions, and double storey extensions. The right option depends on your property, garden space, and what you want to use the room for.
How much does a house extension cost?
Cost depends on the size of the extension, the type of build, and the finish you’re after. We’ll give you a fixed, no obligation quote after an initial survey.
Will I need to move out during the build?
In most cases, no. We work to keep disruption to a minimum and will talk you through what to expect before work begins.
Do you handle everything from design to finishing?
Yes, we manage the full process, including structural work, roofing, electrics, plumbing, and finishing, so you don’t need to coordinate multiple trades yourself.
Do you offer a guarantee on house extensions?
Yes, all our house extension work comes with a 1 year workmanship guarantee.
