Loft Conversions in Crawley
A loft conversion converts an existing roof void into usable living space — typically a bedroom with en-suite — by adding a dormer or rooflights, strengthening the floor, forming a staircase and meeting Building Regulations for insulation, structure and fire escape.
In Crawley, that covers Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush. Crawley combines postwar new-town neighbourhoods with older pockets around Ifield, Three Bridges and Southgate, and sits close to Gatwick Airport with strong transport links into London and along the M23. Housing stock ranges from 1950s–70s estate homes to Victorian terraces and more recent developments, which means project requirements vary considerably from one street to the next.

Property styles in Crawley
Crawley's housing mix includes postwar semis and terraces across the New Town neighbourhoods, Victorian and Edwardian houses around the older Ifield and Southgate areas, and newer estate housing on the town's edges. Many properties are well suited to rear or side-return extensions where garden depth allows, and loft conversions are common in the older stock.
Planning considerations
Crawley Borough Council is the local planning authority. Ifield village and parts of the old town centre fall within conservation areas, which affects permitted development rights and materials on visible elevations. Properties near Gatwick Airport may also be subject to safeguarding or noise-related planning considerations, which we check at feasibility stage.

FAQs
Loft Conversions in Crawley: FAQs
Do you provide loft conversions across all of Crawley?
Yes, we cover the RH10 and RH11 postcode areas in full, including Ifield, Three Bridges, Southgate, Furnace Green, Broadfield, Pound Hill, Maidenbower, Northgate, West Green, Langley Green, Tilgate, Gossops Green, Bewbush.
Do I need planning permission for a loft conversion?
Many loft conversions fall under permitted development if the added roof volume stays within set limits (typically 40m³ for terraced houses, 50m³ for semi-detached and detached) and materials match the existing house. Conversions on designated land, in conservation areas, or exceeding those limits need a full planning application, which we confirm at survey.
How much head height do I need for a loft conversion?
As a general guide, at least 2.2–2.3m from the top of the ceiling joist to the underside of the ridge gives a workable conversion, though this varies with roof pitch and the design chosen. We measure this precisely during the feasibility survey.
Do you cover both RH10 and RH11 in Crawley?
