Loft conversions

A loft conversion turns unused roof space into a bedroom, office or bathroom without adding to your home’s footprint. It brings together structural work, carpentry, insulation, plastering and finishing, all of which our team covers. Many loft conversions can be built under permitted development, depending on the size and the type of house, but every loft conversion needs Building Regulations approval.

Garage conversions

Converting a garage is a practical way to add an office, playroom, bedroom or bathroom. One of our Google reviewers describes a project where we converted their garage into an office and a new bathroom as part of a larger renovation. Garage conversions normally need Building Regulations approval. They often fall under permitted development, but some homes, particularly on newer estates, have had those rights removed, so it is worth checking with your council first.

Reconfiguring the space you have

Sometimes the best conversion is a better layout. The same project combined a lounge, hall and kitchen into one large living space. That kind of reconfiguration usually involves removing load-bearing walls and fitting steel beams, which we handle in-house alongside the finishing work.

What to expect

We start by listening to how you want to use the space, then explain what is involved, which approvals are likely to be needed and how the work will be sequenced. You will have a clear point of contact throughout, and our team carries the project through to plastering, decorating and the final details.
