Design, planning and build for Porthleven renovation
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. A TR13 site visit comes before a Porthleven sketch, every time — Porthleven is the most southerly port on mainland Britain, AONB-designated, with a working harbour, dramatic winter swell and a terraced cliff-edge of Victorian cottages, with a building stock that leans toward modern coastal homes set back from the cliff and Victorian terraces.
Porthleven sits in West Cornwall — just off the A30; covering TR13 from Helston, Breage, Ashton outward.

Why Porthleven is its own job.
Cornwall Council's lens on Porthleven is consistent: porthleven Conservation Area covers the harbour and most residential streets; AONB designation extends across the whole parish. Coastal exposure and views from the South West Coast Path are routine planning considerations. For renovation specifically, parts of Porthleven 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; coastal salt-laden air around Porthleven drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Porthleven project as a TR13-area job first — not a generic Cornwall job with a postcode bolted on. The modern coastal homes set back from the cliff that dominate Porthleven (and continue out toward Breage) set the tone for any renovation scheme here.
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 Porthleven.
01
Listed and curtilage-listed properties need Listed Building Consent for many internal alterations that wouldn't normally need approval.
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
Original fireplaces, slate floors, beams and joinery are often worth rescuing; the design conversation should start with what stays, not what goes.
04
Asbestos surveys are standard for anything pre-2000 — we factor a survey into the programme before stripping out begins.

Who this is for
Our footing in West Cornwall
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a renovation enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Porthleven questions has seen the detail built.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
Scope
Where our work starts and stops on a TR13 project
Not every project needs every stage. On a Porthleven job we scope to what the site and the consent route actually require.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Page purpose
Drawings only, or drawings through to handover in Porthleven?
Both routes are open on a TR13 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Porthleven clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the TR13 scope, not as one opaque figure

Porthleven Renovations — local questions answered.
- We live in the house. Can a renovation in Porthleven be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Porthleven are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- How much does a full renovation cost in Porthleven?
- 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. In Porthleven specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
