Renovations for Treen (TR19)
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. Working in Treen means starting from the TR19 context — Treen is a coastal village in the TR19 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward bungalows and granite cottages.
Treen sits in Penwith — covering TR19 from St Buryan, Truro, St Austell outward.

Local proof — Most Treen homeowners come to us after a renovation quote elsewhere felt vague on planning — we lead with feasibility instead.

Renovations considerations specific to Treen.
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
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
03
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.
04
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
Local context
Why Treen is its own job.
In Treen the planning picture is specific: coastal setting and landscape sensitivity mean rooflines, glazing, drainage and external materials need careful handling from the first sketch. 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 Treen drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a Treen (TR19) project different from a generic Cornwall scheme — and is the whole reason we work this way. On bungalows in particular — the kind you'll also find toward Newquay — the renovation brief always has to read the existing fabric first.
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.

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