Mansard Extensions in Weybridge
The Most Space a Loft Conversion Can Give You
When a dormer or hip-to-gable extension wouldn't give you enough space, a mansard extension reshapes the rear roof into a steep, near-vertical form, so we can create the largest usable loft space your property allows.

When Standard Loft Options Still Aren't Enough Space
Some homes, particularly period and terraced properties with limited existing roof volume, simply can't gain enough usable space from a dormer or hip-to-gable extension alone. The roof shape itself is the limiting factor.
A mansard extension addresses this by reshaping most or all of the rear roof slope into a steep, near-vertical wall with a flat section at the top, maximising headroom and floor space across almost the full footprint of the house below. It's the most substantial loft conversion option, and usually the one that delivers the most additional space.
What a Mansard Extension Could Create for Your Home
- The largest usable loft space of any conversion approach, often across the full width of the house
- A genuine full-height room rather than one limited by a sloping ceiling
- A practical option where a dormer or hip-to-gable extension wouldn't give you enough
- Room for more than one new space, such as a bedroom and an ensuite together
- A well-established approach on period and terraced properties with limited roof volume
What Our Weybridge Neighbours Say About the Quality of Our Work
This review is from a loft extension customer, and reflects how we approach loft conversion work, mansard extensions included.
We recently had a loft extension completed by the House Extensions Weybridge team, and we couldn't be happier with the results. From start to finish, the whole experience was smooth, professional and genuinely enjoyable.
As our family is growing, we really needed the extra space, and the team delivered exactly what we hoped for. The quality of the workmanship is excellent, and every detail was handled with care and precision. It's clear they take real pride in what they do.
What really stood out to me and my husband Tim is that they are such a lovely family-run business. Everyone we dealt with was friendly, approachable and always willing to go the extra mile to make sure we were happy. Their communication throughout the project was great, and they kept everything on track despite the usual challenges that come with building work.
They are also incredibly hard working — always punctual, tidy and respectful of our home, which made a big difference while the work was ongoing. We're so pleased with our new space and grateful for all their hard work.

Mansard Extensions for Weybridge Homes
The Victorian and Edwardian terraces near Weybridge town centre, within the KT13 postcode area, were generally built with a shallower roof pitch and less loft volume than the 1920s and '30s houses further out, which limits what a straightforward dormer or hip-to-gable extension can achieve.
A mansard extension is built for exactly this situation, reshaping most of the rear roof rather than working within its existing form, so it tends to deliver a proportionally much larger gain on an older, smaller-roofed Weybridge property than the same approach would on a house with more roof space to begin with.
For a period terrace near the town centre where a family needs more than one extra room out of the loft, a mansard extension is usually the option that makes the space worth the structural work involved.

How is a mansard extension different from a dormer?

Planning applications for Weybridge are handled by Elmbridge Borough Council, and we can talk through what your project is likely to involve.
