New Builds Carlyon Bay: PL25 planning, South Cornwall fabric
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. A PL25 site visit comes before a Carlyon Bay sketch, every time — Carlyon Bay is a holiday-coast settlement in the PL25 area, with strong second-home demand and exposed coastal building conditions, with a building stock that leans toward detached houses and second homes.
Carlyon Bay sits in South Cornwall — just off the A39; covering PL25 from St Austell, Bugle, St Dennis outward.

Why Carlyon Bay is its own job.
Planning scrutiny often focuses on visual impact, occupancy, parking, overlooking and whether replacement buildings respect the coastal edge. That sets the scene before any design work begins. For new build specifically, coastal salt-laden air around Carlyon Bay drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. It's the kind of detail that decides whether a Carlyon Bay application gets approved at eight weeks or stalls in committee. The detached houses that dominate Carlyon Bay (and continue out toward St Dennis) 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 Carlyon Bay.
01
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
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
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
04
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
Page purpose
Drawings only, or drawings through to handover in Carlyon Bay?
Both routes are open on a PL25 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Carlyon Bay 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 PL25 scope, not as one opaque figure
Scope
Where our work starts and stops on a PL25 project

Existing and proposed plans, elevations, site and block plans drawn to validation standard.
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.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.

Carlyon Bay New Builds — local questions answered.
- We live in the house. Can a new build in Carlyon Bay 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 Carlyon Bay 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 Carlyon Bay?
- 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. In Carlyon Bay specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
