01 โ€” Construction

Construction that works around you.

Every project starts with a different brief. A new home has to feel personal. An extension needs to belong to the house it changes. And every build needs to be delivered with care, clarity and control.

At BSL Construction, we bring experienced project management and skilled trades together under one accountable team โ€” giving you a smoother journey from the first site meeting to the moment we hand over the keys.

Kitchens

A new kitchen touches every trade in the house — building, plumbing, electrics, gas, plastering, tiling and decorating. We handle all of it under one accountable team, so the units, the worktops and the services all line up and the room is finished properly.

Bathrooms

A bathroom is one of the most trade-heavy rooms in a home — plumbing, electrics, tanking, tiling, plastering, ventilation and decoration all in a small, wet space. We handle every part of it under one accountable team, so it's watertight, level and finished to a high standard.

Roofing

New roofs, re-roofs, flat roofs and repairs — carried out by our own roofers with the scaffolding, guttering, leadwork, insulation and making-good handled by the same team. Left watertight, cleared down, and backed by a workmanship guarantee.
