FAQs
Garden Rooms & Offices in Horley: FAQs
Do you provide garden rooms & offices 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 garden room?
Most garden rooms fall under permitted development provided they are single-storey, set back from the boundary where required, and stay within height and garden-coverage limits. Larger structures, those closer to a boundary, or on designated land may need a full application, which we check for your specific garden.
Can a garden room be used all year round?
Yes, provided it is properly insulated in the walls, roof and floor and fitted with heating — this is what distinguishes a garden room from a summerhouse or garden shed, which are not designed for year-round comfort.
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.
