Port Isaac new builds — a North Cornwall studio
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 Port Isaac, that work is shaped by the place itself — Port Isaac is a tight working fishing village on the rugged north coast, internationally recognised through TV (Doc Martin), with one of the densest Conservation Areas in Cornwall and severe access constraints, with a building stock that leans toward fishermen's cottages on Squeezy Belly Alley and around the harbour and converted lofts and chapels.
Port Isaac sits in North Cornwall — covering PL29 from Polzeath outward.

Port Isaac New Builds — local questions answered.
- Can I build a new house on my plot in Port Isaac?
- 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. In Port Isaac specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- What's a replacement dwelling and is mine eligible?
- If a habitable dwelling exists on the plot, you can often replace it — within volumetric and design constraints set by Cornwall's Local Plan. Derelict structures sometimes qualify, sometimes don't, depending on lawful use history.
Local context
Why Port Isaac is its own job.
The planning backdrop in North Cornwall is real, not abstract: conservation Area covers the entire historic harbour; AONB and Heritage Coast across the parish. Access for construction is famously difficult — narrow lanes, steep grades, no on-street parking. For new build specifically, parts of Port Isaac 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 Port Isaac 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. Treat the PL29 parish brief as the design brief and the Port Isaac application has somewhere to land. Whether the project is on fishermen's cottages on Squeezy Belly Alley and around the harbour in the centre or further out toward Polzeath, the new build response is locally tuned.
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 Port Isaac.
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
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
03
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
04
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
Our process
How a Port Isaac new build project runs.
Step 1
Plot review
Site visit, planning history check, designation review and an honest feasibility verdict.
Step 2
Concept design
Sketches that test the plot in massing, orientation and approach before any drawings are committed.
Step 3
Planning
Pre-app, full planning, consultee management and condition discharge.
Step 4
Technical design and build prep
Building regs, structural design, services strategy and contractor procurement.
Step 5
Construction and handover
Build delivered under contract administration with regular client reviews.
Most bespoke new builds run eighteen to thirty months from instruction to keys, depending on site, planning route and build complexity.
Local fabric

Building stock
Across Port Isaac (PL29) we work on fishermen's cottages on Squeezy Belly Alley and around the harbour, Victorian villas above the village, modern carefully detailed coastal homes, converted lofts and chapels. Each stock type drives a different new build response — fishermen's cottages on Squeezy Belly Alley and around the harbour in particular needs careful detailing here.
Parish & policy
Port Isaac is its own town in North Cornwall, with planning history that's specific to the PL29 catchment.
Coverage
We cover PL29 from our studio, with regular new build jobs also running in Polzeath, Tintagel. Most Port Isaac site visits get booked within the same week.
What does a first Port Isaac consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL29 plot and follow up with a written feasibility note inside a week — no obligation either way.
