Richmond's terraces and semis make excellent loft conversions. An L-shaped dormer suits most terraces with a back addition, and a rear dormer or hip to gable suits semis, giving a double bedroom and an en-suite.
With so many conservation areas in Richmond, a dormer often needs planning permission and a careful design. Where Permitted Development applies, we confirm it with a Lawful Development Certificate from Richmond upon Thames council. Either way, we will be straight with you about what is realistic before you spend anything.
We are based nearby in Hounslow and manage the whole conversion, including Party Wall notices.

Do I need planning permission for a loft conversion in Richmond?
Many loft conversions are Permitted Development, which we confirm with a Lawful Development Certificate. In conservation areas, or where Permitted Development rights have been removed, you need planning permission from Richmond upon Thames council. We check before we draw anything.
How long does it take?
A dormer conversion usually takes 8 to 12 weeks on site. A Velux conversion takes 4 to 6 weeks.
