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.
