Our services
Whatever your roof shape or budget, we'll design and build a conversion that transforms the space you already own into the room you actually need.
The simplest and most affordable way to create a new room. If your loft already has enough headroom, we install roof windows, insulate, floor and fit a staircase — no major structural changes needed.
Typical cost: £25,000 – £40,000 · Timeframe: 6–8 weeks
A box-shaped extension that projects from the rear roof slope, adding generous headroom and usable floor space. The most popular choice for a new bedroom or home office in Windsor's terraced and semi-detached homes.
Typical cost: £35,000 – £55,000 · Timeframe: 10–12 weeks
We convert a sloping side roof into a vertical gable wall, dramatically increasing the usable space inside. Ideal for semi-detached and detached homes with a hipped roof.
Typical cost: £45,000 – £65,000 · Timeframe: 10–14 weeks
The largest conversion type, with a near-vertical rear slope that effectively adds a whole new floor. Frequently chosen for terraced homes in Windsor and Maidenhead wanting maximum space.
Typical cost: £50,000 – £75,000 · Timeframe: 12–16 weeks
An L-shaped dormer wraps around the rear of your property to create two connected rooms — ideal for a master bedroom with en-suite and dressing area.
