Hackney's Victorian terrace stock — particularly in Dalston, London Fields, Clapton and Hackney Central — is architecturally ideal for L-shaped dormer loft conversions that use both the main roof and back addition roof.
L-Shaped Dormers in E2, E5, E8, N16
An L-shaped dormer extends across the main rear roof slope and down over the back addition, yielding a double bedroom, bathroom and landing on what was previously dead roof space. Most qualify as Permitted Development within the 40m³ volumetric limit. Conservation areas in Clapton, De Beauvoir and Stoke Newington may impose materials conditions.
Structural Considerations
Victorian joist floors need upgrading to habitable standard. Party wall notices are required where the existing party wall is affected. rcbGroup handles party wall notices as standard.
Costs
Rear dormer: £40,000–£60,000. L-shaped dormer: £55,000–£75,000. Second-fix materials client-supplied.
