Renovations Crowlas: TR20 planning, West Cornwall fabric
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 TR20 plot rarely works elsewhere — Crowlas is a commuter village in the TR20 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward modern estates and bungalows.
Crowlas sits in West Cornwall — covering TR20 from Penzance, Chyandour, Sancreed outward.

Why Crowlas is its own job.
Applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. That sets the scene before any design work begins. 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. It's the kind of detail that decides whether a Crowlas application gets approved at eight weeks or stalls in committee. The modern estates that dominate Crowlas (and continue out toward Sancreed) 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 Crowlas.
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
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
04
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.

Crowlas Renovations — local questions answered.
- 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. In Crowlas specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
