Renovations that reads St Winnow properly
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 St Winnow version of this work has its own character — St Winnow is a rural parish in the PL22 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward converted barns and smallholdings.
St Winnow sits in South Cornwall — covering PL22 from Lostwithiel, Lerryn, Lanlivery outward.

The PL22 constraints that shape a renovation brief.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
Who this is for
St Winnow 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 St Winnow is its own job.
Around St Winnow (PL22), open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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. Reading St Winnow properly up front saves more time than any drawing tool ever will. Most of our renovation work in St Winnow lands on converted barns, with detailing that has to nod to the wider Lerryn 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 St Winnow.
01
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.
02
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
03
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
04
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.

FAQs
St Winnow 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 St Winnow 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.
- 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.
