Renovations & Remodels in Porthtowan
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. The Porthtowan version of this work has its own character — Porthtowan is a north coast surf cove village, AONB and World Heritage designated, with a tight valley setting and predominantly twentieth-century housing stock, with a building stock that leans toward modern coastal architect builds and replacement dwellings.
Porthtowan sits in North Cornwall — covering TR4 from St Agnes, Redruth outward.

Who this is for
Porthtowan 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 Porthtowan is its own job.
AONB, Heritage Coast and World Heritage Site designations apply. Cliff-edge and valley-side sites face strict controls; mining heritage is a recurring planning consideration. 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; coastal salt-laden air around Porthtowan drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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. So every Porthtowan job runs as a TR4-specific piece of work — local policy, local fabric, local builders. Most of our renovation work in Porthtowan lands on modern coastal architect builds, with detailing that has to nod to the wider Redruth streetscape.
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 Porthtowan.
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.

FAQs
Porthtowan 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 Porthtowan 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.
- 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.
