Renovations & Remodels in Twelveheads
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 Twelveheads version of this work has its own character — Twelveheads is a former mining settlement in the TR4 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward chapel conversions and post-war estates.
Twelveheads sits in Mid Cornwall — covering TR4 from Truro, St Michael Penkivel, Calenick outward.

Local watch-list
The TR4 constraints that shape a renovation brief.
Watch #1
World Heritage Site assessment on changes visible in the mining landscape
Watch #2
Tighter Local Plan tests on isolated rural dwellings
Who this is for
Twelveheads runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every renovation enquiry from the use-class up.
Local context
Why Twelveheads is its own job.
Mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. For renovation specifically, the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; 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. So every Twelveheads job runs as a TR4-specific piece of work — local policy, local fabric, local builders. Most of our renovation work in Twelveheads lands on chapel conversions, with detailing that has to nod to the wider St Michael Penkivel streetscape.
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 Twelveheads.
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
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
04
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.

FAQs
Twelveheads 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 Twelveheads 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.
- 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.
- 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.
Twelveheads is part of Truro
Twelveheads sits inside the Truro catchment — we cover both as one renovation territory.
