Loft & Dormer Conversions

We manage the whole conversion under one roof, from design and planning through structural work to the final fit-out. Being carpentry-led, the structural timber work and finish joinery are handled in-house to a high standard, with certified trades for electrics and plumbing, all to UK building regulations. Established in 2000 and led by master carpenter James Doughty, we have completed over 1,000 projects across Suffolk.

What we offer

Types of Loft Conversion We Build

From a simple rooflight conversion to a full mansard, we will recommend the right approach for your roof and your budget.

Velux Conversions

The simplest and most affordable option where the existing roof has enough head height, with windows set into the roof line.

Dormer Conversions

A box-shaped extension out from the roof that adds significant headroom and floor space, ideal for a bedroom with an en-suite.

Hip-to-Gable Conversions

Extending a sloping side roof out to a vertical gable to create extra width, common on semi-detached and detached Suffolk homes.

Mansard Conversions

The most extensive option, reshaping the roof to maximise space, often used in conservation areas and on period properties.

Design & Planning

We assess your roof, head height and structure, design a layout, and handle any planning needs and building regulations.

Structural Work

Steel beams, floor joists, dormers and staircases installed by skilled tradespeople, all overseen by master carpenter James Doughty.

Fit-Out & Finish

Insulation, plastering, electrics, flooring, joinery and decoration leave you with a warm, finished room ready to use.
