Mid Cornwall · PL24
One studio for renovation in Tregrehan
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. The way we approach renovation in Tregrehan starts with a measured walk-round — Tregrehan is an estate-influenced village in the PL24 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward detached homes and small infill plots.
Tregrehan sits in Mid Cornwall — covering PL24 from St Austell, Bugle, St Dennis outward.

Our process
How a Tregrehan renovation project runs.
Step 1
Survey
Measured survey, condition assessment, services check and listed status review.
Step 2
Design
Layout options, material strategy and a clear list of what stays and what changes.
Step 3
Approvals
Listed Building Consent and building regulations as needed.
Step 4
Strip-out and works
Carefully sequenced demolition, structural works and rebuild.
Step 5
Finish and handover
Joinery, decoration, snagging and documentation pack.
Whole-house renovations typically run six to fourteen months on site; partial remodels two to four months.
Local proof — Our Mid Cornwall workload means a Tregrehan renovation project never has to wait for an out-of-county team to drive down.

Renovations considerations specific to Tregrehan.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
02
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
03
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.
04
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
Local context
Why Tregrehan is its own job.
Two things shape a Tregrehan application: parish character and policy. On policy — landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. 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. Get that local reading right and the rest of the Tregrehan programme tends to run on time. On detached homes in particular — the kind you'll also find toward Nanpean — the renovation brief always has to read the existing fabric first.
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.

Parish & policy
Tregrehan sits in the parish of Tregrehan, which matters for how parish-level consultation lands on a renovation application.

FAQs
Tregrehan Renovations — local questions answered.
- 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. In Tregrehan specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- Can I live in the house during the work?
- Sometimes yes, often no. Single-room remodels and phased work can be liveable; whole-house renovations involving rewires, replumbing or floor lifting almost never are. We're honest about this at the brief.
- 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.
