Dormer, hip-to-gable & full conversions

The space you already own, put to work

A loft conversion adds a bedroom, bathroom or home office without touching your garden — and it's often the single best value-adding project you can do. We build flat-roof dormers, hip-to-gable conversions and Velux rooflight conversions, including striking weatherboard-clad finishes that lift the whole look of the house.

Inside, we make the awkward spaces earn their keep: fitted wardrobes in the eaves, bespoke storage under the new stairs, and staircases built to match the rest of your home.

What you could do

Ways to convert your loft

The right conversion depends on your roof shape, headroom and budget — here's the menu.

Flat-roof dormer

The most popular conversion — maximum headroom and floor space, ideal for a double bedroom.

L-shaped dormer

Two connected dormers for larger roofs; often fits a bedroom and a full bathroom.

Hip-to-gable

Extends a hipped roof into a vertical gable — unlocks lofts that seem too small to convert.

Velux / rooflight

Keeps the roofline untouched; the fastest, most cost-effective conversion where headroom allows.

En-suite in the eaves

A cleverly planned shower room tucked into the slope — a must for a master suite.

Fitted eaves storage

Wardrobes and drawers built into the awkward angles, so no space is wasted.

SpaceA bedroom you already own

The average loft holds a double bedroom and en-suite — space sitting unused above your head.

ValueThe classic value-adder

Loft conversions are widely regarded as one of the highest value-adding home improvements in the UK.

DisruptionBuilt mostly from outside

Scaffold goes up, the roof opens from above — home life carries on below until the staircase goes in.

“Dan and his team did an incredible job on my loft conversion. They were always respectful of neighbours and how they worked within my house, and communicated well on timelines. I'm really happy with the work.”
