New Builds Mousehole: TR19 planning, West 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. A TR19 site visit comes before a Mousehole sketch, every time — Mousehole is a famously photogenic fishing village south of Newlyn, almost entirely within the Conservation Area and AONB, with a tiny harbour and dense lanes of granite cottages, with a building stock that leans toward modern infill carefully matched to traditional vernacular and Victorian villas above the village.
Mousehole sits in West Cornwall — covering TR19 from Newlyn outward.

Who this is for
Mousehole 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.
Local watch-list
Mousehole-specific issues we screen on the first visit.

Conservation Area material and fenestration controls in central Mousehole
Watch #2
AONB landscape-impact scrutiny on visible elevations
Watch #3

Local proof — Most Mousehole new build clients we work with are second-time builders — they've seen the templated approach fail once already.

Mousehole 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 Mousehole specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
Local context
Why Mousehole is its own job.
Almost the entire village is within both the Conservation Area and AONB; new openings, dormers, render colours and roof materials all attract close scrutiny. Paul parish operates with strong policy resistance to second-home use. That sets the scene before any design work begins. For new build specifically, parts of Mousehole sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Mousehole drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. It's the kind of detail that decides whether a Mousehole application gets approved at eight weeks or stalls in committee. The modern infill carefully matched to traditional vernacular that dominate Mousehole (and continue out toward Newlyn) 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 Mousehole.
01
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
02
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
03
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
04
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
Our process
How a Mousehole 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 West Cornwall studio is the right fit for Mousehole new build.
Building stock
Across Mousehole (TR19) we work on granite fishing cottages, Victorian villas above the village, modern infill carefully matched to traditional vernacular, converted net-lofts. Each stock type drives a different new build response — modern infill carefully matched to traditional vernacular in particular needs careful detailing here.
Parish & policy
Mousehole sits in the parish of Paul, which matters for how parish-level consultation lands on a new build application.
Coverage
We cover TR19 from our studio, with regular new build jobs also running in Newlyn, Penzance. Most Mousehole site visits get booked within the same week.
How quickly can you visit a Mousehole site?
Usually within the same week. Mousehole (TR19) is on our regular West Cornwall run, alongside Newlyn, Penzance. First visits are free and you'll get an honest feasibility view inside seven days.
