Design, planning and build for Portwrinkle renovation
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. A PL11 site visit comes before a Portwrinkle sketch, every time — Portwrinkle is a holiday-coast settlement in the PL11 area, with strong second-home demand and exposed coastal building conditions, with a building stock that leans toward holiday lets and coastal bungalows.
Portwrinkle sits in East Cornwall — covering PL11 from Torpoint, Millbrook, Antony outward.

Why Portwrinkle is its own job.
Cornwall Council's lens on Portwrinkle is consistent: planning scrutiny often focuses on visual impact, occupancy, parking, overlooking and whether replacement buildings respect the coastal edge. For renovation specifically, the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Portwrinkle drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Portwrinkle project as a PL11-area job first — not a generic Cornwall job with a postcode bolted on. The holiday lets that dominate Portwrinkle (and continue out toward Antony) 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 Portwrinkle.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
02
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.
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.

Portwrinkle 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 Portwrinkle specifically, we'd start by checking AONB landscape sensitivity 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 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.
- 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.
