From single storey additions to full double storey builds and loft conversions, every extension project planned, coordinated, and built by Warren, with the same attention to detail on the structure as the finish

Planning an extension in Somerset or Bristol means getting the brief right before anything goes on paper. The wrong layout, or one that wasn't properly challenged at the start, is expensive to fix once a build is underway.
Warren visits the plot, understands how you want to use the space, and raises any constraints before anything is drawn or priced. From there, Britton's Properties manages the full project, structural engineer, groundworks, build, and internal fit-out, as one coordinated job.
