Helston 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. In Helston, that work is shaped by the place itself — Helston is the gateway to the Lizard Peninsula and Cornwall's most westerly market town, famous for the Furry Dance and a steep granite-paved Coinagehall Street, with a building stock that leans toward Georgian townhouses and post-war semis.
Helston sits in West Cornwall — just off the A394; with Truro the closest city; covering TR13 from Porthleven, Mullion outward.

Who this is for
In Helston the new build brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.

Helston New Builds — local questions answered.
- Can I build a new house on my plot in Helston?
- 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. In Helston specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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 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.
- 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.
Local context
Why Helston is its own job.
Locally, the Conservation Area covers the medieval core and Coinagehall Street; shop frontages, sash windows and listed building stock dominate the design conversation. RNAS Culdrose to the south sets some height and roofline constraints in the southern parishes. For new build specifically, parts of Helston sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. Which is why we scope Helston projects parish-up, not template-down — the TR13 context shapes the design from day one. Whether the project is on Georgian townhouses in the centre or further out toward Porthleven, 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.

New Builds considerations specific to Helston.
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
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
03
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
04
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.

Most bespoke new builds run eighteen to thirty months from instruction to keys, depending on site, planning route and build complexity.
Local fabric
Choosing a new build team that actually knows TR13.
Building stock
Across Helston (TR13) we work on Georgian townhouses, granite-and-slate terraces, Victorian villas, post-war semis, modern estates at Trannack. Each stock type drives a different new build response — Georgian townhouses in particular needs careful detailing here.
Parish & policy
Helston is its own town in West Cornwall, with planning history that's specific to the TR13 catchment.
Coverage
We cover TR13 from our studio, with regular new build jobs also running in Porthleven, Mullion. Most Helston site visits get booked within the same week.
What does a first Helston consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR13 plot and follow up with a written feasibility note inside a week — no obligation either way.
