Dormer Loft Conversions
A dormer loft conversion in Clapham adds extra headroom by building out from the roof slope. It’s one of the most common types, giving you space for a large bedroom, home office, or even a second bathroom.
Single Dormer Loft Conversions
A single dormer in Clapham is a smaller version of the rear dormer. It’s ideal if your roof can’t handle large changes. It still creates more space, just on a smaller scale.
Full Width Dormer Loft Conversions
A full-width dormer in Clapham stretches across the whole rear roof, creating a big, box-like extension. This adds maximum space in your existing loft.
L-Shaped Dormer Loft Conversions
L-Shaped Dormer Loft Conversions
An L-shaped dormer in Clapham combines two dormers at right angles. It’s perfect for properties with an extended rear or corner plot.
Rear Dormer Loft Extension
A rear dormer loft extension in Clapham is ideal for those wanting to build straight out from the back of their roof. It works well with terraced and semi-detached homes.
Pitched Dormer Extension
A pitched dormer in Clapham has a sloped roof, rather than flat. This helps it blend seamlessly with traditional rooflines, particularly in conservation areas.
Hip to Gable Loft Conversion
A hip to gable loft conversion in Clapham straightens a sloped “hip” roof to form a vertical gable. It’s perfect for semi-detached homes needing extra headroom and floor space.
Mansard Loft Conversion
A mansard loft conversion in Clapham alters the roof shape entirely. The rear slope becomes almost vertical, maximising space. This style is ideal for bespoke lofts with an en-suite or large master room.
Velux (Roof Light) Loft Conversion
A Velux loft conversion in Clapham uses roof windows without altering the roof shape. It’s cost-effective and ideal for lofts with sufficient head height.
New Build Loft Conversion
Even new build homes in Clapham can benefit from a loft conversion. We assess your property and recommend the most effective design and layout.

We recently had a rear dormer conversion completed in Leytonstone, and I couldn’t be more pleased with the outcome. From the very first consultation, Neolofts were professional, knowledgeable, and a pleasure to work with. We wanted something a little more bespoke—a bay view window and a zinc dormer—which many other companies seemed reluctant to take on. Neolofts, however, were more than happy to embrace our vision. Tony, our project manager, was fantastic throughout, ensuring everything ran smoothly and to a high standard. A special mention must go to Graham, the architect, who not only understood exactly what we were hoping to achieve but also managed to secure planning permission for our more unique design. The craftsmanship is excellent, and the finish is simply stunning. If you’re looking for a loft conversion in East London and want a company that truly listens and delivers something beyond the ordinary, I wouldn’t hesitate to recommend Neolofts.Posted on Carly DefriendTrustindex verifies that the original source of the review is Google. ★★★★★ Neo Lofts – Top Class Loft Conversion in Walthamstow Had our loft done by Neo Lofts, and honestly, couldn’t be happier.

FAQs About Loft Conversions in Clapham
What is a dormer loft conversion, and how much does it cost?
A dormer adds space by building outward from the roof. It’s one of the most popular types of loft builds. Costs vary but usually start around £35,000, depending on size, finishes, and whether your home needs extra work like a rear mansard loft conversion or loft extension.
How much does a hip to gable loft conversion cost in Clapham?
A hip to gable loft conversion can cost between £40,000 and £55,000. The final price depends on the home’s structure, roof type, and whether it’s part of a wider home extension or conversion may include interior features like an en suite.
What factors influence the cost of a loft conversion or extension?
Key factors include the type of conversion, head height, roof structure, and whether you require planning permission. The quality of finishes, insulation, and windows, like Velux, also impacts cost. Whether your build is a rear dormer, mansard conversion, or conversion or extension matters too.
Can you suggest loft conversion ideas to maximise space and functionality?
Consider a front and rear mansard loft, or combining a loft conversion and extension for larger homes. Add storage under the eaves, built-in wardrobes, or split levels. Many loft conversions become home offices, studios, or even extra lounges for a growing family.
Is an attic conversion a worthwhile investment in Clapham housing market?
Absolutely. A conversion in Clapham can increase property value, improve liveability, and avoid the need to move.
