One studio for new build in Seaton
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. Seaton sits in East Cornwall, and that geography ends up in the drawings — Seaton is a holiday-coast settlement in the PL11 area, with strong second-home demand and exposed coastal building conditions, with a building stock that leans toward holiday lets and detached houses.
Seaton sits in East Cornwall — covering PL11 from Looe, Duloe, Herodsfoot outward.

Our process
How a Seaton 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 proof — Our East Cornwall workload means a Seaton new build project never has to wait for an out-of-county team to drive down.

New Builds considerations specific to Seaton.
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
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
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
Local context
Why Seaton is its own job.
Two things shape a Seaton application: parish character and policy. On policy — planning scrutiny often focuses on visual impact, occupancy, parking, overlooking and whether replacement buildings respect the coastal edge. 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 Seaton drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Get that local reading right and the rest of the Seaton programme tends to run on time. On holiday lets in particular — the kind you'll also find toward Lanreath — the new build brief always has to read the existing fabric first.
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.

Seaton is part of Looe
Seaton sits inside the Looe catchment — we cover both as one new build territory.

What sets a Seaton new build brief apart.
Building stock
Across Seaton (PL11) we work on coastal bungalows, holiday lets, second homes, detached houses, replacement dwellings. Each stock type drives a different new build response — holiday lets in particular needs careful detailing here.
Parish & policy
Seaton sits in the parish of Seaton, which matters for how parish-level consultation lands on a new build application.
Coverage
We cover PL11 from our studio, with regular new build jobs also running in Looe, Duloe, Herodsfoot. Most Seaton site visits get booked within the same week.

FAQs
Seaton New Builds — local questions answered.
- 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. In Seaton specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
- 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.
