New Builds for Kenwyn (TR1)
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. The way we approach new build in Kenwyn starts with a measured walk-round — Kenwyn is a commuter village in the TR1 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward older cottages and post-war semis.
Kenwyn sits in Mid Cornwall — just off the A390; covering TR1 from Truro, St Michael Penkivel, Calenick outward.

Page purpose
Drawings only, or drawings through to handover in Kenwyn?
Both routes are open on a TR1 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Kenwyn clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the TR1 scope, not as one opaque figure
Scope
Scope options for Kenwyn clients
These stages can be bought separately. Most TR1 projects use three of them.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Local watch-list
Kenwyn-specific issues we screen on the first visit.
Watch #1
Conservation Area controls on materials, window proportions and roof form through central Kenwyn
Watch #2
Trussed roofs and shallow foundations in the later TR1 estates, which change the structural strategy
Who this is for
Straight facts about working with us here
- Applications for Kenwyn are handled through Cornwall Council, with St Austell the nearest planning office we deal with regularly.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
What we focus on
New Builds considerations specific to Kenwyn.
01
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
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.

Local context
Why Kenwyn is its own job.
In Kenwyn the planning picture is specific: applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. For new build specifically, parts of Kenwyn sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. That local reading is what makes a Kenwyn (TR1) project different from a generic Cornwall scheme — and is the whole reason we work this way. On older cottages in particular — the kind you'll also find toward Malpas — the new build brief always has to read the existing fabric first.
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.
Our process
How a Kenwyn 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
Kenwyn New Builds — local questions answered.
- 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. In Kenwyn specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- 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.
- We live in the house. Can a new build in Kenwyn be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Kenwyn are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
Kenwyn is part of Truro
Kenwyn sits inside the Truro catchment — we cover both as one new build territory.

Where to go next from Kenwyn
Kenwyn is covered from our Truro run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.

Nearby places we cover
A new build in Kenwyn stands or falls on how well it reads the street — we treat that as the design brief, not an afterthought. Here that means the Conservation Area boundary decides the route before the design does.
