— Four types, one survey

It is hard to know which loft
conversion fits your home.

We work out what your roof type allows during the free home survey. Most UK homes can take a dormer or a Velux — the most popular two options.

Most popular

Dormer Loft Conversion

From £35,000 →

Extends out from the roof to add full standing headroom. Works on almost any terrace, semi or detached. Usually does not need planning permission.
Bright loft conversion bedroom with Velux roof windows letting in daylight

Velux / Rooflight

From £25,000

Simplest and cheapest. No structural change. Great when you already have head height.
Hip-to-gable loft conversion on a 1930s semi-detached UK house

Hip-to-Gable

From £45,000

For semis and detached with hipped roofs. Maximises usable space.

Also available

Mansard loft conversion on a Victorian London townhouse

Mansard Loft Conversion

From £55,000 · Planning permission usually required

The most space you can add. Rebuilds the entire roof slope into a near-vertical wall. Best for Victorian and Edwardian terraces and townhouses.

"We had a fixed-price quote in four days and they actually stuck to it. No surprise extras when we hit the structural week. Best contractor decision we have made."
★★★★★
Dormer conversion + ensuite · Three-bed Victorian terrace · January 2026
"They handled the planning application themselves. We did not have to chase Leeds council once. Build came in £350 under quote."
James & Anna · Bradford BD3 · Hip-to-gable + bedroom + bathroom
"We stayed in the house the whole 11 weeks. Daily cleanup, one point of contact, no nasty surprises. We have already recommended them to neighbours."
