South London’s Victorian terraces, period villas and converted houses are some of the most conversion-friendly properties in the capital. From Clapham to Dulwich, Battersea to Brixton — Prime Loft is active throughout.
South London’s long Victorian terraces — with their characteristic rear outriggers — are perfectly designed for L-shaped dormer conversions. The grand Victorian villas of Dulwich and Herne Hill suit the architectural ambition of a mansard. Battersea and Brixton offer some of the strongest ROI figures in London as property values have risen dramatically.
