One studio for new build in Constantine
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 Constantine starts with a measured walk-round — Constantine is an AONB village inland from Helford on a steep granite hillside, with a substantial fifteenth-century church and a tight Conservation Area covering the village core, with a building stock that leans toward traditional granite cottages and Edwardian villas.
Constantine sits in South Cornwall — covering TR11 from Mawnan Smith, Gweek, Mabe Burnthouse outward.

Our process
How a Constantine 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 proof — Most Constantine new build clients we work with are second-time builders — they've seen the templated approach fail once already.

New Builds considerations specific to Constantine.
01
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
02
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
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.
Local context
Why Constantine is its own job.
Two things shape a Constantine application: parish character and policy. On policy — conservation Area covers the village including the church; AONB across the parish. Granite quarrying heritage and views to the Helford shape design considerations. For new build specifically, parts of Constantine 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; 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. Get that local reading right and the rest of the Constantine programme tends to run on time. On traditional granite cottages in particular — the kind you'll also find toward Ponsanooth — 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.

One TR11 studio, one new build job — start to finish.
Building stock
Across Constantine (TR11) we work on traditional granite cottages, Victorian terraces, Edwardian villas, modern infill on field-edge plots, barn conversions. Each stock type drives a different new build response — traditional granite cottages in particular needs careful detailing here.
Parish & policy
Constantine is its own town in South Cornwall, with planning history that's specific to the TR11 catchment.
Coverage
We cover TR11 from our studio, with regular new build jobs also running in Mawnan Smith, Gweek, Mabe Burnthouse. Most Constantine site visits get booked within the same week.
Can you handle both planning and build in Constantine?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Constantine builder we can stop at a tender-ready Full Plans pack instead.

Constantine 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.
FAQs
Constantine 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 Constantine 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.
- 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.
- 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.
