Lower Boscaswell renovations — a Penwith 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. In Lower Boscaswell, that work is shaped by the place itself — Lower Boscaswell is a former mining settlement in the TR19 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward workers cottages and post-war estates.
Lower Boscaswell sits in Penwith — covering TR19 from Pendeen, Morvah, Trewellard outward.

Lower Boscaswell 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 Lower Boscaswell 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.
- 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.
- 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.
Local context
Why Lower Boscaswell is its own job.
The planning backdrop in Penwith is real, not abstract: mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; 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 TR19 parish brief as the design brief and the Lower Boscaswell application has somewhere to land. Whether the project is on workers cottages in the centre or further out toward Pendeen, 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 Lower Boscaswell.
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
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
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.
