Our Basement Conversion Services
A basement conversion in Somerset is a major structural undertaking.
We provide the heavy lifting and technical precision needed for a successful build.
Structural Underpinning
If your existing basement doesn’t have enough height, we can safely lower the floor level through professional underpinning. This allows us to create a room with full ceiling heights without compromising the building’s integrity.
Specialist Waterproofing
The success of a basement conversion largely depends on moisture control. We install industry-leading Type C Cavity Drainage Systems to ensure your space remains bone-dry, meeting the strictest Building Regulations for residential use.
Lighting & Ventilation
We use clever architectural solutions to flood the converted basement with natural light. We also install mechanical ventilation and heat recovery (MVHR) systems to ensure the air remains fresh and perfectly climate-controlled.
The Full Fit-Out
What will you do with your new space? We handle the entire fit-out – whether it’s for a home cinema, private gym, home office, or a wine cellar – from start to finish.
Decades of Happy Clients
We’re incredibly proud of the reputation we’ve built over the last 35+ years.
