Extensions & conversions, done properly
Extensions, loft and garage conversions and conservatories that add real space and value. Everything managed by one team, from the first site visit to the final finish, with care and attention to detail on every job.

Single and two-storey extensions tied cleanly into the existing structure and roofline.
Loft & dormer conversions
Full width dormers and loft rooms with proper stairs, light and headroom, like our Crowlas conversion.
Garage & outbuilding conversions
Garages and outbuildings turned into warm, usable living space.
Conservatories & garden rooms
Light-filled additions built on proper footings and tied in weathertight.
Structural openings & steels
Knock-throughs and openings formed with the right support, signed off to building regs.
Planning & building regs
Drawings, approvals and building control handled with trusted local architects.
Why choose Ben Luck Construction
Adding space changes how a whole home works, and here is why Cornwall homeowners trust us to add theirs.
Tied in properly
New structure joined to old with the right steels, footings and weathering, so it never reads as an afterthought.
Space that earns its keep
We plan extensions and conversions around how you actually live, not just how they look on a drawing.
Planning and regs handled
We work with architects, planners and building control so approvals never hold your project hostage.
Lived-in friendly
Most extensions happen around a family still using the house. We keep the site tight, tidy and safe.
