New Builds New Mill: TR20 planning, Penwith 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. A TR20 site visit comes before a New Mill sketch, every time — New Mill is a small rural hamlet in the TR20 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward small infill homes and bungalows.
New Mill sits in Penwith — covering TR20 from Penzance, Chyandour, Sancreed outward.
- Rural / open-countryside policy area
- ✓ Cornwall Council regulars across every sub-area
- ✓ Plain-English feasibility before any drawings
- ✓ Measured-survey accuracy from day one
- ✓ One studio — design, planning and build under one roof
Local proof — We typically have one or two new build jobs live in the TR20 area at any time, so the local planning officers know our drawings on sight.

Why New Mill 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 New Mill application gets approved at eight weeks or stalls in committee. The small infill homes that dominate New Mill (and continue out toward Sancreed) 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 New Mill.
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.

New Mill 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 New Mill 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.
