Loft Conversions in Eltham
Eltham is one of South East London's most active extension markets — its interwar and post-war semi-detached stock, with generous plot widths, is ideal for side extensions, loft conversions and full-footprint rear additions.
Loft Conversions in Eltham — what to expect
Eltham hip-to-gable loft conversions are a staple for us. The typical SE9 semi has a hipped roof end that gains significant width when converted to a gable, allowing a dormer of real usable size. Many proceed under permitted development. L-shaped dormers on detached properties are also common.
Eltham property types
Interwar semi-detached and detached, bungalows, 1960s–80s estates. The property type affects which loft conversions approach works best — we'll advise from the first call.
