New Builds Bissoe: TR4 planning, Mid 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. Every Bissoe project we take on begins with reading the local context — Bissoe is a former mining settlement in the TR4 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward miners cottages and post-war estates.
Bissoe sits in Mid Cornwall — covering TR4 from Truro, St Michael Penkivel, Calenick outward.
- Cornish Mining World Heritage Site
- Rural / open-countryside policy area
- ✓ Plain-English feasibility before any drawings
- ✓ World Heritage Site experience built into the fee
- ✓ One studio — design, planning and build under one roof
- ✓ Local to Mid Cornwall — not a national franchise
Local proof — We typically have one or two new build jobs live in the TR4 area at any time, so the local planning officers know our drawings on sight.

Why Bissoe is its own job.
Mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. That sets the scene before any design work begins. For new build specifically, the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; 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 Bissoe application gets approved at eight weeks or stalls in committee. The miners cottages that dominate Bissoe (and continue out toward Calenick) 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 Bissoe.
01
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
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
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
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
Our process
How a Bissoe 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 a Mid Cornwall studio is the right fit for Bissoe new build.

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