Our Services

Loft Conversions

Transforming unused loft space into functional, well-built living areas built to last.

Turn unused loft space into a bedroom, office or living area. We handle the structural work, the services and the finish, all under one roof.

Loft Conversions by Marwells Construction

A loft conversion is one of the most effective ways to add living space without reducing your garden. It also involves important structural decisions, from new floor joists and steel beams to staircase design and roof alterations.

Our engineers assess your existing roof structure, prepare the calculations required for Building Control and coordinate the electrical, heating and ventilation work alongside the build. The result is a comfortable, well-insulated space that is properly engineered and completed to a high standard.
