What we offer
Velux Conversion
Velux loft conversions, also known as roof-light conversions are a popular choice. The roof line remains unaltered because the windows are installed fitting flush to the original roof line.
Pitched Roof Dormer
A Pitched Roof Dormer makes for an attractive addition to your property. Rear facing dormers are usually covered under ‘permitted development’ but front facing dormers will require planning permisison.
Full Rear Dormer
A Full Rear Dormer extends the entire width of your roof at the back of the property, creating significant additional space with a flat roof and vertical walls.
Mansard
A Mansard conversion alters the structure of the roof itself, with a steep rear slope and a flat roof, maximizing internal loft space - ideal for a period property or urban home.
Rear Extension
Extend your home into your garden to create a bright, open-plan space. A rear extension is perfect for larger kitchens or living areas.

How long does a loft conversion or extension take?
A typical loft conversion takes 6–10 weeks, depending on the type and structural complexity. A home extension usually takes 10–16 weeks, with larger or double-storey builds requiring more time. Before work begins, we provide a clear programme outlining each phase of the project.
02 - Do I need planning permission?
