A carpentry company for the bigger jobs
Loft conversions, timber framing and full renovations across Cornwall.

MSB Carpentry & Construction is a carpentry and construction company based in St Columb and covering Cornwall. We take on full property renovations and refurbishments through to new build developments, and we look after every stage of the work.
Most of what we do is structural: loft conversions, timber frame houses and extensions built on site, roofs, and the complete carpentry on new homes for a local developer. If you have a new build, a renovation or a loft you want turned into a proper room, that is the work we are set up for.
