Eco new builds in Polzeath — sustainable spec that stacks up
An eco new-build in Polzeath doesn't have to be Passivhaus-certified to make sense. Timber-frame construction, wood-fibre insulation, triple glazing and a properly sized air-source heat pump get you 85–90% of Passivhaus performance for a build premium under 6%. On PL27 plots, this is the pragmatic middle ground. 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. On a Polzeath site, the brief always meets the place — Polzeath is the surfing village above one of north Cornwall's biggest sandy beaches, AONB-designated, with a holiday-let-heavy housing stock and increasing replacement-dwelling activity, with a building stock that leans toward 1930s coastal villas and high-end replacement dwellings.
Polzeath sits in North Cornwall — covering PL27 from Rock, Trebetherick, St Minver outward.

Local proof — Most Polzeath homeowners come to us after a new build quote elsewhere felt vague on planning — we lead with feasibility instead.

Why Polzeath is its own job.
The planning backdrop in North Cornwall is real, not abstract: aONB and Heritage Coast designations across the village; cliff and dune-edge sites are tightly controlled. Local plan policy on second homes and holiday lets is being progressively tightened. For new build 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; coastal salt-laden air around Polzeath 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 PL27 parish brief as the design brief and the Polzeath application has somewhere to land. Whether the project is on 1930s coastal villas in the centre or further out toward St Minver, 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 Polzeath.
01
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
02
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
03
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
04
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
Our process
How a Polzeath 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
Why Polzeath homeowners pick a local studio for new build.
Building stock
Across Polzeath (PL27) we work on 1930s coastal villas, 1960s bungalows above the beach, modern coastal architect builds, high-end replacement dwellings. Each stock type drives a different new build response — 1930s coastal villas in particular needs careful detailing here.
Parish & policy
Polzeath sits in the parish of St Minver, which matters for how parish-level consultation lands on a new build application.
Coverage
We cover PL27 from our studio, with regular new build jobs also running in Rock, Trebetherick, St Minver. Most Polzeath site visits get booked within the same week.
What does a first Polzeath consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL27 plot and follow up with a written feasibility note inside a week — no obligation either way.

Polzeath New Builds — local questions answered.
- Is timber-frame or block best for eco in Polzeath?
- Timber-frame nearly every time — lower embodied carbon, faster on-site programme, better air-tightness detailing. The exception is exposed coastal plots where masonry may still win on maintenance.
- What eco heating works in Polzeath?
- Air-source heat pump with underfloor heating downstairs, radiators upstairs. Ground-source only makes sense on plots with borehole space. PV on the roof pays back in 9–12 years at current rates.
- Does eco spec add much cost?
- £3,200–£4,200/m² for sensible eco spec vs £3,000–£4,000 standard. Under 6% premium for major improvements in comfort and running cost.
- 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 Polzeath specifically, we'd start by checking AONB landscape sensitivity 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.
- 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.

Not every Polzeath eco home needs full Passivhaus certification — sensibly specified timber-frame with the right envelope gets most of the benefit for a fraction of the premium.
