What Nairn Homeowners Say About Our House Extension Specialists
Side-return infill extension on our 1930s semi in Nairn. New floor finished with engineered oak running through to the original house. £86100 over 16 weeks, properly programmed. CIAT-registered architect on retainer for the planning drawings.
Compared four extension builders through BestBuilders for the Nairn job. Two FMB-affiliated builders, two not. Went with the one whose references checked out best. CCTV drain survey on day one, no surprises with hidden services. Came in £2100 under quote because the foundations were shallower than feared. Building control sign-off straightforward, no comeback.
Three years on, EPC went from D to B thanks to the spec they used. Builder we found via BestBuilders in Nairn persuaded us into a wider opening to the original house - the flow is so much better. Total £75000. EPC went up two bands - the new envelope spec made a real difference.
