Wandsworth and Balham are among the most active London boroughs for loft conversions. The majority of Victorian terraces here suit L-shaped or rear dormer conversions.
Planning in SW11, SW12, SW17
Most rear dormers qualify as Permitted Development. Conservation areas around Wandsworth Common and Clapham Junction may impose restrictions. Pre-application advice is recommended for these areas.
Typical Costs
Standard rear dormer: £40,000–£65,000. L-shaped dormer: £55,000–£75,000. All structural work, roof modification, staircase, insulation, and first-fix M&E included. Second-fix materials are client-supplied.
Principal Contractor Coordination
Loft conversions involve scaffold, structural steelwork, carpentry, roofing, electrics, plumbing, plastering and decoration — all sequenced trades. rcbGroup coordinates all trades under one contract, one programme, one point of accountability.
