House Extensions in Sissinghurst
Serving Sissinghurst & surrounding areas
Sissinghurst extensions are almost always on small period cottages or converted oasts — both with serious conservation sensitivity due to the village's proximity to Sissinghurst Castle.

House Extensions for Sissinghurst homes
Why Sissinghurst house extensions briefs are different
We work directly with TWBC's heritage officer on every Sissinghurst extension, defaulting to subordinate single-storey designs in matching weatherboard or tile-hung walls. That's what gets approval here.
Sissinghurst is a small but architecturally rich village of converted oast houses, weatherboarded cottages and a tight cluster of farmhouses near The Street.
Local considerations
Proximity to Sissinghurst Castle Garden means heritage officers at Tunbridge Wells take a noticeably tougher view on glazing styles and external finishes.
Many properties sit on heavy clay subsoil that shrinks dramatically in dry summers — we routinely build allowances for seasonal movement into structural design.
Extensions are where ground conditions, sightlines and neighbouring rights-of-light decisions cost real money if missed early. We front-load all three before any drawings are firmed up.
What Sissinghurst clients ask for
Most clients want clarity on fixed cost, end-to-end timeline and how disruptive the kitchen-relocation period will be — we put those in writing on day one.
Recent local project
We added a 22m² sitting-room extension to a weatherboarded cottage off The Street, with single-pitch roof in clay peg tiles and frameless rooflights.

FAQs
House Extensions in Sissinghurst — frequently asked
Is Sissinghurst conservation strict?
Yes — proximity to the Castle gardens means heritage officers take a tougher view than in neighbouring villages.
Can you match existing weatherboarding?
Yes — natural chestnut or painted softwood, feathered or square-edged, to match the original.
How long does a single-storey extension take to build?
From breaking ground to handover is typically 14–18 weeks for a 25–35m² rear extension, including weather-tight shell at week 6–7 and fit-out from week 10.
Do I need building regulations approval as well as planning?
Almost always. Planning approves the principle; building regs approve the construction detail. We submit the building regs application in parallel with planning to save 6–8 weeks.
What guarantee do you give on work in Sissinghurst?
A 5-year workmanship guarantee on everything we build, with manufacturer warranties on materials and fittings passed through unchanged.
