Renovations for St Agnes (TR5)
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. St Agnes sits in North Cornwall, and that geography ends up in the drawings — St Agnes is a former mining village on the north coast with a strong artistic community, AONB and World Heritage designation, and dramatic coastal mining ruins (Wheal Coates) on its doorstep, with a building stock that leans toward Edwardian guesthouses and AONB-sensitive replacement dwellings.
St Agnes sits in North Cornwall — covering TR5 from Porthtowan outward.

Who this is for
St Agnes 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 Agnes is its own job.
In St Agnes the planning picture is specific: conservation Area covers Vicarage Road, Town Hill and the church area. AONB, Heritage Coast and World Heritage Site designations across the parish. Mining heritage shapes most planning conversations. For renovation specifically, parts of St Agnes sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; coastal salt-laden air around St Agnes drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a St Agnes (TR5) project different from a generic Cornwall scheme — and is the whole reason we work this way. On Edwardian guesthouses in particular — the kind you'll also find toward Perranporth — 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.
What we focus on
Renovations considerations specific to St Agnes.
01
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
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.

FAQs
St Agnes Renovations — local questions answered.
- 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. In St Agnes specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
