Bespoke New Builds in Threemilestone
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. Reading Threemilestone on the ground is half of the new build job — Threemilestone is the western residential and retail-park suburb of Truro, with the West Cornwall Hospital site nearby and significant new estate development on the Langarth Garden Village land, with a building stock that leans toward modern Persimmon, Bellway and Wainhomes estates and office and retail conversions.
Threemilestone sits in Mid Cornwall — covering TR3 from Truro, Shortlanesend, Playing Place outward.

Local watch-list
What usually catches new build projects out in Threemilestone.
Watch #1
Parish-level character expectations that don't appear on any policy map
Who this is for
Threemilestone 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 context
Why Threemilestone is its own job.
Outside Conservation Area and AONB. Langarth Garden Village (3,500+ homes) is reshaping the west of Truro with strict design code expectations on adjacent sites. For new build specifically, Threemilestone sits outside the headline designations, which usually gives a slightly more flexible starting point — but parish-level character still matters. So every Threemilestone job runs as a TR3-specific piece of work — local policy, local fabric, local builders. Most of our new build work in Threemilestone lands on modern Persimmon, Bellway and Wainhomes estates, with detailing that has to nod to the wider Playing Place streetscape.
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 Threemilestone.
01
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
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
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
Our process
How a Threemilestone 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.
FAQs
Threemilestone New Builds — local questions answered.
- 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. In Threemilestone specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
