Design, planning and build for Marazion 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 TR17 plot rarely works elsewhere — Marazion sits opposite St Michael's Mount across a tidal causeway and is one of Cornwall's oldest chartered towns, designated AONB for its setting, with a building stock that leans toward granite cottages and modern coastal builds.
Marazion sits in West Cornwall — just off the A30; with Truro the closest city; 3 miles from Penzance.

Who this is for
In Marazion 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.

Marazion 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 Marazion specifically, we'd start by checking the Conservation Area boundary 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.
- We live in the house. Can a new build in Marazion 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 Marazion are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Page purpose
Drawings only, or drawings through to handover in Marazion?
Both routes are open on a TR17 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Marazion 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 TR17 scope, not as one opaque figure
Scope
Where our work starts and stops on a TR17 project
Clients in Marazion take different slices of this list, and that is deliberate.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Who this is for
Our footing in West Cornwall
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Sites we know on the ground here include the area around the causeway and St Michael's Mount.
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Marazion questions has seen the detail built.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.

Local context
Why Marazion is its own job.
Cornwall Council's lens on Marazion is consistent: the whole town centre is within the Conservation Area and the AONB; views to and from St Michael's Mount are a material planning consideration on most schemes. Roof pitches, ridge heights and seaward elevations are tightly controlled. For new build specifically, parts of Marazion sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Marazion drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Marazion project as a TR17-area job first — not a generic Cornwall job with a postcode bolted on. The granite cottages that dominate Marazion (and continue out toward Long Rock) 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.

New Builds considerations specific to Marazion.
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.
