Bespoke New Builds in St Mellion
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 St Mellion version of this work has its own character — St Mellion is an estate-influenced village in the PL12 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward estate cottages and detached homes.
St Mellion sits in East Cornwall — covering PL12 from Saltash, Hatt, Landrake outward.

Local watch-list
Local snags worth knowing before drawing a St Mellion new build.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
Who this is for
St Mellion 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 St Mellion is its own job.
Landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. 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. So every St Mellion job runs as a PL12-specific piece of work — local policy, local fabric, local builders. Most of our new build work in St Mellion lands on estate cottages, with detailing that has to nod to the wider Hatt 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 St Mellion.
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
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
Our process
How a St Mellion 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
St Mellion 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 St Mellion 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.
- 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.
- 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.
- 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.
