Treesmill new build — feasibility first, drawings second
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. Anchor any Treesmill new build in the local fabric and the rest follows — Treesmill is a small rural hamlet in the PL24 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and bungalows.
Treesmill sits in South Cornwall — covering PL24 from Fowey, Golant, Bodinnick outward.
- Rural / open-countryside policy area

Who this is for
Treesmill 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.

Watch #1
Tighter Local Plan tests on isolated rural dwellings
Local proof — Recent new build enquiries from Treesmill have clustered around cottages — we know the route through Cornwall Council on these.

Treesmill 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 Treesmill specifically, we'd start by checking the latest parish-level planning history 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.
- 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.
- 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 Treesmill is its own job.
Locally, the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. Which is why we scope Treesmill projects parish-up, not template-down — the PL24 context shapes the design from day one. Whether the project is on cottages in the centre or further out toward Fowey, the new build response is locally tuned.
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 Treesmill.
01
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
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
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
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 Treesmill 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 Treesmill homeowners pick a local studio for new build.
Building stock
Across Treesmill (PL24) 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
Treesmill sits in the parish of Treesmill, which matters for how parish-level consultation lands on a new build application.
Coverage
We cover PL24 from our studio, with regular new build jobs also running in Fowey, Golant, Bodinnick. Most Treesmill site visits get booked within the same week.
What does a first Treesmill consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL24 plot and follow up with a written feasibility note inside a week — no obligation either way.

Treesmill sits inside the Fowey catchment — we cover both as one new build territory.
