More space, less moving

Room to grow, without leaving

In West London, space is the thing worth having. A loft conversion or extension is often the smartest way to get it, since it avoids the cost and upheaval of moving. An extra bedroom, a home office, or a bigger kitchen can transform how a house works for your family.

Because we're roofers first, we understand the part of these projects that goes wrong most often: the roof. We handle dormers, rooflights, new pitched or flat roofs and all the leadwork and weatherproofing in-house, so the new space is dry, warm and built to last from day one.

Not sure if your loft needs full planning permission? See our guide to loft conversion planning permission, and our London loft conversion cost guide for real, sourced figures by conversion type.

Loft & extension questions

Do I need planning permission for a loft conversion in Fulham? +
Many loft conversions fall under permitted development, but conservation areas — of which West London has many — and certain designs often need planning permission, and all conversions need Building Regulations approval. We'll talk you through what your project is likely to require before you commit.
How much value does a loft conversion add to my home? +
In sought-after parts of West London, a well-built loft conversion that adds a bedroom and bathroom can add significant value and is often one of the most cost-effective ways to gain space without moving. The exact figure depends on the property and the finish, but the extra room almost always pays its way.
Why use a roofer for a loft conversion or extension? +
A loft conversion is, at heart, a major roofing job — new dormers, rooflights, structural changes and all the weatherproofing that goes with them. Because we're roofers as well as builders, the roof and the new space are handled by one team, so nothing falls between trades and the weatherproofing is done properly.
Do you do extensions and general building work too? +
Yes. Alongside loft conversions we carry out rear and side extensions and general building work, including the flat or pitched roofs, leadwork and structural elements involved. It means you can take a project from foundations to finished roof with a single contractor.
