St John renovations — a East Cornwall studio
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. Anchor any St John renovation in the local fabric and the rest follows — St John is a creekside settlement in the PL11 area, with waterside homes, wooded valleys and narrow-lane access shaping the brief, with a building stock that leans toward boat sheds and converted barns.
St John sits in East Cornwall — covering PL11 from Torpoint, Millbrook, Antony outward.

Who this is for
St John runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every renovation enquiry from the use-class up.

St John Renovations — local questions answered.
- 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. In St John 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.
- 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.
- 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 St John is its own job.
The planning backdrop in East Cornwall is real, not abstract: creekside ecology, flood risk, trees and views across the water often matter as much as the building form itself. 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. Treat the PL11 parish brief as the design brief and the St John application has somewhere to land. Whether the project is on boat sheds in the centre or further out toward Torpoint, 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 St John.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
02
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.
03
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
04
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.
