Loft Conversions in Horley
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 Horley, that covers Massetts, Lonsdale, Smallfield, Horley Row, Westvale Park. Horley sits close to Gatwick Airport, with a historic village core and substantial 20th-century residential development around it, making it a popular area for family homeowners looking to extend rather than move.

FAQs
Loft Conversions in Horley: FAQs
Do you provide loft conversions across all of Horley?
Yes, we cover the RH6 postcode area in full, including Massetts, Lonsdale, Smallfield, Horley Row, Westvale Park.
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.
Does living near Gatwick Airport affect planning permission in Horley?
Some development types near the airport are subject to safeguarding consultation with the airport operator as part of the planning process. This does not apply to all projects, and we advise on the specific position for your address.
