Mansard Loft Conversion in Hammersmith, London

A mansard loft conversion in Hammersmith starts from £35,000 and typically takes 10–14 weeks. We handle the whole job, from the first survey to the final sign-off. In short, you get a finished room and one clear price.

A mansard conversion rebuilds the rear of your roof as a near-vertical wall topped with a flat or gently pitched roof. This shape gives you full headroom right across the loft floor, not just down the middle. As a result, it is the most spacious conversion type we offer. It is especially popular for mid-terrace and end-of-terrace homes in busy urban areas, where every extra square metre matters.

London's Victorian and Edwardian terraces suit this type of conversion particularly well. Our local team knows the planning rules and the roof structures common to Hammersmith. As a result, we can advise on the right approach for your home during the free survey, before you commit to anything.

Every mansard loft conversion we build in Hammersmith includes the full package. That means structural design, planning checks, building regulations submission, and project management from start to finish. Better still, you receive a single fixed-price quote, with no hidden costs and no surprises along the way.
