New Builds Halvasso: TR10 planning, South Cornwall fabric
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. What works on a TR10 plot rarely works elsewhere — Halvasso is a small rural hamlet in the TR10 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and small infill homes.
Halvasso sits in South Cornwall — covering TR10 from Penryn, Rame, Mabe outward.

Local proof — Our South Cornwall workload means a Halvasso new build project never has to wait for an out-of-county team to drive down.

Why Halvasso is its own job.
The main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. That sets the scene before any design work begins. 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. It's the kind of detail that decides whether a Halvasso application gets approved at eight weeks or stalls in committee. The cottages that dominate Halvasso (and continue out toward Mabe) 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 Halvasso.
01
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
02
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
03
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
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 Halvasso 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
Choosing a new build team that actually knows TR10.
Building stock
Across Halvasso (TR10) we work on cottages, farmhouses, converted barns, bungalows, small infill homes. Each stock type drives a different new build response — cottages in particular needs careful detailing here.
Parish & policy
Halvasso sits in the parish of Halvasso, which matters for how parish-level consultation lands on a new build application.

Halvasso New Builds — local questions answered.
- 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. In Halvasso specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
Halvasso is part of Penryn
Halvasso sits inside the Penryn catchment — we cover both as one new build territory.
