What Hamilton Homeowners Say About Our House Extension Specialists
Steel-framed wraparound on our Victorian terrace in Hamilton. Glazed corner of the extension brings southerly daylight deep into the plan. £102500 for the full spec including extension fit-out. Trial pit done day one to confirm foundation depth was workable.
Compared four extension builders through BestBuilders for the Hamilton job. Chose the design-and-build option for single-point accountability. Trial pit confirmed foundation depth on day two, no over-engineering. Came to £108370 across 16 weeks. EPC went up two bands thanks to the new spec.
Two summers in, the threshold detail still drains perfectly with no puddling. Builder we found via BestBuilders in Hamilton recommended an in-floor zone control - underfloor heating runs only where needed. Total £83820. Stamp duty saved by extending out rather than moving up.
