Design, planning and build for Porkellis 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. What works on a TR13 plot rarely works elsewhere — Porkellis is a former mining settlement in the TR13 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward post-war estates and workers cottages.
Porkellis sits in West Cornwall — just off the A30; covering TR13 from Helston, Breage, Ashton outward.

Why Porkellis is its own job.
Cornwall Council's lens on Porkellis is consistent: mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. 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 Porkellis project as a TR13-area job first — not a generic Cornwall job with a postcode bolted on. The post-war estates that dominate Porkellis (and continue out toward Ashton) 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 Porkellis.
01
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
02
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
03
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
04
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
Page purpose
Drawings only, or drawings through to handover in Porkellis?
Both routes are open on a TR13 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Porkellis 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 TR13 scope, not as one opaque figure
Scope
Where our work starts and stops on a TR13 project
These stages can be bought separately. Most TR13 projects use three of them.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.

Porkellis New Builds — local questions answered.
- 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. In Porkellis specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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 Porkellis 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 Porkellis are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
Porkellis is part of Helston
