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 — just off the A38; covering PL12 from Saltash, Hatt, Landrake outward.

Who this is for
In St Mellion 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.

1:10 and 1:20 details for the parts of the job builders normally have to guess at.

Full design and build
One contract from first sketch to handover, with the same team on paper and on site.

Other work we do around St Mellion
St Mellion is covered from our Saltash 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.
Page purpose
Drawings only, or drawings through to handover in St Mellion?
Both routes are open on a PL12 project, and the honest answer depends on whether you already have a builder you trust. Plenty of St Mellion 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 PL12 scope, not as one opaque figure
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.

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.
- We live in the house. Can a new build in St Mellion 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 St Mellion are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
