Renovations for Trethurgy (PL26)
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 Trethurgy means starting from the PL26 context — Trethurgy is a small rural hamlet in the PL26 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and converted barns.
Trethurgy sits in Mid Cornwall — covering PL26 from St Austell, Bugle, St Dennis outward.

Step 3
Approvals
Listed Building Consent and building regulations as needed.
Step 4
Strip-out and works
Carefully sequenced demolition, structural works and rebuild.
Step 5
Finish and handover
Joinery, decoration, snagging and documentation pack.
Whole-house renovations typically run six to fourteen months on site; partial remodels two to four months.
Local proof — Most Trethurgy homeowners come to us after a renovation quote elsewhere felt vague on planning — we lead with feasibility instead.

Renovations considerations specific to Trethurgy.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
02
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
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
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
Local context
Why Trethurgy is its own job.
In Trethurgy the planning picture is specific: 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. That local reading is what makes a Trethurgy (PL26) project different from a generic Cornwall scheme — and is the whole reason we work this way. On cottages in particular — the kind you'll also find toward Nanpean — 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
Trethurgy Renovations — local questions answered.
- 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. In Trethurgy specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
