Polyphant renovation — feasibility first, drawings second
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. On a Polyphant site, the brief always meets the place — Polyphant is a small rural hamlet in the PL15 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and bungalows.
Polyphant sits in East Cornwall — covering PL15 from Launceston, Warbstow, North Petherwin outward.

Tighter Local Plan tests on isolated rural dwellings
Local proof — Most Polyphant homeowners come to us after a renovation quote elsewhere felt vague on planning — we lead with feasibility instead.

Polyphant 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 Polyphant 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 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.
- 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.
Local context
Why Polyphant is its own job.
Locally, the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. Which is why we scope Polyphant projects parish-up, not template-down — the PL15 context shapes the design from day one. Whether the project is on cottages in the centre or further out toward Launceston, the renovation response is locally tuned.
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 Polyphant.
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
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
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
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
