The 1930s semis and terraces across Whitton and Heathfield make good loft conversions. On a hipped-roof semi, a hip to gable with a rear dormer usually adds a double bedroom and a shower room. On terraces, a rear dormer or L-shaped dormer gives the most space.
Most Whitton lofts can be done under Permitted Development, which we confirm with a Lawful Development Certificate from Richmond upon Thames council. We also handle the Party Wall notices you will need with your neighbour.
We are based nearby in Hounslow and manage the whole conversion, from the loft survey to the Building Control certificate.

Do I need planning permission for a loft conversion in Whitton?
