Compare the cost of building your extension with each specialist and check their company reviews. You can also speak to each property extension professional either online or by phone, before booking any work with them.
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.

I build a wall with Sydney and while the process had many hoops and sign offs that we had to go through Sydney was very responsive over the entire process. His expertise in design and ordering of material ment we were able to complete without too much challenges. His work was neat and he was always around managing his teams. I would recommend Sydney for your next project. Calin Forbay

I couldn't be happier with the service I received from Sidney Davids of Sidney Davids Projects. He assisted me with my property plans and was efficient, responsive, professional, and friendly throughout the entire process. His turnaround time was incredibly fast, and his attention to detail gave me complete confidence. I was super impressed with the quality of his work and the excellent service he provided. A well-deserved 10/10! I highly recommend Sidney and will gladly use his services again and again.
