St Mabyn new builds — a East 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. Anchor any St Mabyn new build in the local fabric and the rest follows — St Mabyn is a substantial inland village south-east of Wadebridge, with a fifteenth-century church and a tight Conservation Area at its core, with a building stock that leans toward modern small estates and traditional granite cottages.
St Mabyn sits in East Cornwall — covering PL30 from Wadebridge outward.

Who this is for
St Mabyn runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every new build enquiry from the use-class up.

Tighter Local Plan tests on isolated rural dwellings
Local proof — We typically have one or two new build jobs live in the PL30 area at any time, so the local planning officers know our drawings on sight.

St Mabyn New Builds — local questions answered.
- 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 St Mabyn 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.
- 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.
- 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.
Local context
Why St Mabyn is its own job.
The planning backdrop in East Cornwall is real, not abstract: conservation Area covers the village core including the church. Active parish council with detailed input on edge-of-village schemes. For new build specifically, parts of St Mabyn sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 PL30 parish brief as the design brief and the St Mabyn application has somewhere to land. Whether the project is on modern small estates in the centre or further out toward Wadebridge, 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 St Mabyn.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
03
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
04
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
