General
In most cases, no. Loft conversions fall under Permitted Development Rights, as long as:
• The new structure does not exceed 40m³ for terraced houses or 50m³ for detached/semi-detached houses.
• It doesn’t extend beyond the plane of the existing roof facing the road.
• It’s not in a conservation area or a flat.
However, if your design exceeds PD limits or you're in a restricted area, you’ll need to apply for planning permission.
We offer all major types, including:
• Velux (Rooflight) Conversion – least invasive, uses skylights.
• Dormer Conversion – extends the roof vertically to add headroom.
• Hip-to-Gable Conversion – straightens a sloped end to create more internal space.
• Mansard Conversion – alters the roof slope to a near-vertical wall for maximum space.
