Loft Conversions East Finchley N2: Best Types for Local Properties
East Finchley's large Edwardian semi-detached houses are ideally suited to hip to gable loft conversions— replacing the sloping hip end with a vertical gable to create a full-height loft room. Victorian terraced houses suit dormer and L-shaped dormer conversions. Many East Finchley terraces have a back addition alongside the rear — these properties are particularly well suited to L-shaped dormers which create two bedrooms rather than one.

Can it be done under permitted development?
Most London loft conversions on houses need no planning application. A rear dormer, a hip-to-gable or an L-shaped dormer is permitted development within 40 m³ on a terrace and 50 m³ on a semi or detached house, provided the property is a house (not a flat) and not in a conservation area or on an Article 4 street, and we apply for a Lawful Development Certificate on every one so the position is confirmed in writing before work starts. Our fixed-price permitted development lofts start from £32,400 inc. VAT (£27,000 + VAT) for a Velux loft and £56,400 inc. VAT (£47,000 + VAT) for a rear dormer, at economy specification, design and build inclusive. See our permitted development projects page for every product with its from-price and the checks we run before we confirm a project qualifies.
