In terms of cost, construction of single-storey extensions is more expensive than that of side return house extensions. Wrap around or double-storey ones will cost you even more. The construction cost also depends on your taste, your ability to plan, the type of property and the overall size of your dream home. Regardless of these, the Proficiency team will ensure you get the most value for the money you set aside for the entire building project. You will have access to a project manager who will ensure the right materials are bought, the team works for the required number of hours and that the project is managed in such a way that you will save on costs. They do more with less so that all clients are satisfied with the overall service.


Proficiency Design and Build Company has a team of recommended builders in Kennington that handle every project with care. They’re builders with expertise and commitment that is unmatched. With an FMB insurance and NICEIC approval, Proficiency provides a 15-year structural guarantee on all their structural work.
