Design, planning and build for Treverva new build
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. Every Treverva project we take on begins with reading the local context — Treverva is a rural parish in the TR10 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward scattered modern homes and smallholdings.
Treverva sits in South Cornwall — covering TR10 from Falmouth, Flushing, Budock Water outward.

Local proof — Our South Cornwall workload means a Treverva new build project never has to wait for an out-of-county team to drive down.

Why Treverva is its own job.
Cornwall Council's lens on Treverva is consistent: open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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. That's why we treat every Treverva project as a TR10-area job first — not a generic Cornwall job with a postcode bolted on. The scattered modern homes that dominate Treverva (and continue out toward Budock Water) set the tone for any new build scheme here.
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 Treverva.
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
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.
Our process
How a Treverva 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

Most bespoke new builds run eighteen to thirty months from instruction to keys, depending on site, planning route and build complexity.

Treverva New Builds — local questions answered.
- 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. In Treverva specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
Treverva is part of Falmouth
