Read our top tips for planning the kitchen extension of your dreams
The cost of building an extension is determined by a number of factors, including size, specification, and your location. You may be planning a basement conversion, a single storey extension, a downstairs toilet extension, or an extension over your garage. Whatever you have in mind, our experts will take a detailed brief in order to provide an accurate quote for the work.
In many cases, you can extend your home under Permitted Development (PD). For example, under PD you can extend a detached property by 8m to the rear, if it’s a single-storey extension, or by 3m if it’s double. Check with your local council and your extension specialist before you get too far into the planning stages, because your project may not meet all the criteria for PD.
Most insurers won’t cover any loss or damage incurred while a property is undergoing alteration or renovation. If you’re carrying out extension works and managing the project yourself, it’s worth discussing your project with an insurance provider, before any work begins. You may need to arrange a specific extension policy to cover the new works and the existing structure. It’s also worth enquiring about a 10-year structural warranty, as this can be provided on some new extension works.

Absolutely great experience working with the GemBuilt crew! We went with them after interviewing 4 other vendors and cancelling a prior contract with a different vendor. We found them via word of mouth (neighbors). They delivered on what they committed for from start to finish. Communication was great. His team pays attention to detail and anytime we had something we wanted adjusted or fixed it was done. I would absolutely recommend GemBuilt to everyone and we will be using them again in the future for other projects

I hired GemBuilt after talking with two neighbors who raved about working with them. We wanted to remodel our kitchen and open up our space by removing a wall. When we first met, they proposed a layout that didn't make intuitive sense to me. They asked me to trust him and I am so glad I did! They have a good eye for use of space and for the smallest details. We love our kitchen and are so happy we followed their advice every step of the way.
