Design, planning and build for Treliske renovation
Cornish housing stock is brilliant and infuriating in equal measure. We renovate cottages, farmhouses, mid-century homes and post-war estates — opening up layouts, fixing damp, adding light and bringing the property up to a standard worth living in. What works on a TR1 plot rarely works elsewhere — Treliske is a town-edge neighbourhood in the TR1 area, where modern housing, larger gardens and edge-of-settlement plots create practical development opportunities, with a building stock that leans toward infill plots and detached houses.
Treliske sits in Mid Cornwall — covering TR1 from Truro, St Michael Penkivel, Calenick outward.

Why Treliske is its own job.
Cornwall Council's lens on Treliske is consistent: neighbour amenity, highways, drainage and the transition from built-up edge to countryside are usually the planning pressure points. For renovation specifically, Cornwall Council's Local Plan applies tighter tests to isolated rural dwellings here, so design rationale and policy fit need to be set out clearly from the outset. That's why we treat every Treliske project as a TR1-area job first — not a generic Cornwall job with a postcode bolted on. The infill plots that dominate Treliske (and continue out toward Calenick) set the tone for any renovation scheme here.
Planning note
Most Cornish renovations don't need planning — but listed status, curtilage listing, Conservation Area designation and material changes can all change that picture.
What we focus on
Renovations considerations specific to Treliske.
01
Older Cornish properties are often built with cob, rubble or solid granite — modern insulation strategies that work in cavity walls cause damp problems in solid construction. Breathable build-ups matter.
02
Damp in Cornish cottages is usually a moisture management problem, not a chemical injection problem — fixing the cause is cheaper long term than treating the symptom.
03
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
04
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.

Treliske Renovations — local questions answered.
- Do I need planning permission to renovate internally?
- Usually no — except on listed buildings, where Listed Building Consent is needed for many internal alterations. We confirm the position before any wall comes down. In Treliske specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- How much does a full renovation cost in Cornwall?
- A whole-house renovation typically lands between £1,800 and £3,000 per square metre depending on condition, listed status and finish level. We survey before quoting and don't price by guesswork.
- Can you renovate and extend at the same time?
- Yes, and often it's the right call — the planning, regs and disruption all happen once instead of twice. We design and price it as a single project.
- What about damp and old walls?
- We assess the cause first — usually rising damp myths, blocked vents, hard cement renders trapping moisture, or roofs needing attention. A breathable repair strategy fixes most of it without chemical intervention.
- How long does a renovation take?
- Single rooms in weeks, kitchens in two to three months, whole-house renovations in six to fourteen months depending on size and listed status.
