Built for West Sussex gardens

The county changes character quickly - Wealden clay and mature trees in the north, chalk and wind exposure closer to the Downs. Both change the groundworks, and neither is a problem if it is designed for rather than discovered halfway through.

We survey levels, drainage, access and root protection before quoting, then build the room, the terrace it opens onto and the planting around it as one job.

Planning in Horsham, Crawley and Mid Sussex districts

The three district councils apply permitted development consistently, and most rooms qualify. The exceptions cluster in the High Weald AONB, conservation areas in Horsham and Cuckfield, and around listed properties.

We check your address against the designations before quoting and manage any application needed.

West Sussex garden room questions

Which West Sussex areas do you cover?
Horsham, Crawley, Haywards Heath, Burgess Hill, Cuckfield, Lindfield, East Grinstead, Billingshurst, Storrington and the villages between them, with longer trips for larger builds.
What does a garden room cost in West Sussex?
From around £25,000 fully finished for a compact insulated room, typically £35,000 to £50,000 for a larger family room or gym with a terrace.
Do I need permission in the High Weald AONB?
Permitted development rights still apply in an AONB for most garden rooms, but size and siting are scrutinised more closely and cladding choice matters. We check the designation on your plot first.
Can you work with restricted side access?
Yes. Older town gardens in Horsham and Haywards Heath often have a narrow side passage, so we build in sections sized to the access rather than craning over the house.
