Bespoke New Builds in Porthleven
A bespoke new build is the longest project we do, and the most rewarding. From plot appraisal through planning, building regulations and construction, you work with one team from the first sketch to the handover walk-round. In Porthleven, that work is shaped by the place itself — 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 fishermen's cottages above the harbour and Victorian terraces.

Local context
Why Porthleven is its own job.
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 new build 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.
Planning note
Cornwall's planning policy on new dwellings is among the most restrictive in England outside Greater London. The first conversation should be a planning conversation, not a design one.
What we focus on
New Builds considerations specific to Porthleven.
01
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
02
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
03
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.

FAQs
Porthleven New Builds — common questions.
- How much does a new build cost?
- Realistic budgets in Cornwall start around £2,800 per square metre for a good-quality build and rise quickly with bespoke joinery, large glazing, complex sites and high-spec finishes. We work to your number, not against it. In Porthleven specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Can I build a new house on my plot in Cornwall?
- Sometimes yes, sometimes no — and the honest answer needs a planning policy review of the specific site. Settlement boundary, designations, access and policy on isolated dwellings all weigh in. We give a frank read at first consultation rather than a sales pitch.
- How long does the whole project take?
- Allow six to twelve months for design and approvals, then ten to fourteen months on site for a typical four-bedroom new build. Complex sites or long planning routes extend that.
- What about utilities, drainage and access?
- All designed and applied for as part of the package — water, electric, off-mains drainage where mains isn't viable, and highways access agreement with Cornwall Council where required.
