Design, planning and build for Perranuthnoe new build
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. Every Perranuthnoe project we take on begins with reading the local context — Perranuthnoe is a small AONB cliff-top village between Marazion and Praa Sands, with a sandy cove, twelfth-century church and a tight, well-preserved Conservation Area at its centre, with a building stock that leans toward 1960s coastal bungalows and Edwardian villas.
Perranuthnoe sits in West Cornwall — just off the A30; covering TR20 from Marazion, Goldsithney outward.

Why Perranuthnoe is its own job.
Cornwall Council's lens on Perranuthnoe is consistent: conservation Area covers the village core and church; AONB extends across the parish. Isolated dwelling policy applies in the open countryside between settlements. For new build specifically, parts of Perranuthnoe 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 Perranuthnoe 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. That's why we treat every Perranuthnoe project as a TR20-area job first — not a generic Cornwall job with a postcode bolted on. The 1960s coastal bungalows that dominate Perranuthnoe (and continue out toward Praa Sands) set the tone for any new build scheme here.
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 Perranuthnoe.
01
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
02
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
03
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
04
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
Page purpose
Drawings only, or drawings through to handover in Perranuthnoe?
Both routes are open on a TR20 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Perranuthnoe 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 TR20 scope, not as one opaque figure
Scope
Where our work starts and stops on a TR20 project
Not every project needs every stage. On a Perranuthnoe job we scope to what the site and the consent route actually require.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
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 new build enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Perranuthnoe 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.

Local fabric
Why Perranuthnoe homeowners pick a local studio for new build.
Building stock
Across Perranuthnoe (TR20) we work on traditional granite farm cottages, Edwardian villas, 1960s coastal bungalows, modern AONB-sensitive replacements. Each stock type drives a different new build response — 1960s coastal bungalows in particular needs careful detailing here.
Parish & policy
Perranuthnoe sits in the parish of Perranuthnoe, which matters for how parish-level consultation lands on a new build application.

Perranuthnoe New Builds — local questions answered.
- Can I build a new house on my plot in Perranuthnoe?
- 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 Perranuthnoe specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Can you handle a self-build for me?
- Yes — from feasibility to handover. Many of our clients start as 'self-builders' on paper, then hand the actual build to us once they realise how much project management it takes.
- We live in the house. Can a new build in Perranuthnoe 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 Perranuthnoe 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 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.
- 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.
- 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.
Perranuthnoe is part of Marazion
Perranuthnoe sits inside the Marazion catchment — we cover both as one new build territory.
