One studio for new build in South Petherwin
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. South Petherwin sits in East Cornwall, and that geography ends up in the drawings — South Petherwin is a rural parish in the PL15 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward farmhouses and rural cottages.
South Petherwin sits in East Cornwall — just off the A38; covering PL15 from Launceston, Warbstow, North Petherwin outward.

Page purpose
Drawings only, or drawings through to handover in South Petherwin?
Both routes are open on a PL15 project, and the honest answer depends on whether you already have a builder you trust. Plenty of South Petherwin 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 PL15 scope, not as one opaque figure

What we focus on
New Builds considerations specific to South Petherwin.
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.

Local context
Why South Petherwin is its own job.
Two things shape a South Petherwin application: parish character and policy. On policy — open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. For new build specifically, 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. Get that local reading right and the rest of the South Petherwin programme tends to run on time. On farmhouses in particular — the kind you'll also find toward Boyton — 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.

FAQs
South Petherwin New Builds — local questions answered.
- 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. In South Petherwin specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- We live in the house. Can a new build in South Petherwin 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 South Petherwin are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
