One studio for new build in Goldsithney
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 way we approach new build in Goldsithney starts with a measured walk-round — Goldsithney is a small linear village on the B3280 inland from Marazion — and home to the Trademark Designs studio, so we know its lanes, water table and planning history personally, with a building stock that leans toward modern infill and barn conversions and Victorian semis.
Goldsithney sits in West Cornwall — covering TR20 from Marazion, Perranuthnoe outward.

Our process
How a Goldsithney 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.
Local proof — Our West Cornwall workload means a Goldsithney new build project never has to wait for an out-of-county team to drive down.

New Builds considerations specific to Goldsithney.
01
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
Local context
Why Goldsithney is its own job.
Two things shape a Goldsithney application: parish character and policy. On policy — outside the Conservation Area but the village fringes border the AONB; Perranuthnoe parish policy applies. Infill and barn conversion proposals dominate the parish planning workload. 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. Get that local reading right and the rest of the Goldsithney programme tends to run on time. On modern infill and barn conversions in particular — the kind you'll also find toward Marazion — the new build brief always has to read the existing fabric first.
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.

Goldsithney is part of Marazion
Goldsithney sits inside the Marazion catchment — we cover both as one new build territory.

One TR20 studio, one new build job — start to finish.
Building stock
Across Goldsithney (TR20) we work on traditional granite cottages, Victorian semis, 1960s and 1970s bungalows, modern infill and barn conversions. Each stock type drives a different new build response — modern infill and barn conversions in particular needs careful detailing here.
Parish & policy
Goldsithney sits in the parish of Perranuthnoe, which matters for how parish-level consultation lands on a new build application.
Coverage
We cover TR20 from our studio, with regular new build jobs also running in Marazion, Perranuthnoe, Long Rock. Most Goldsithney site visits get booked within the same week.

FAQs
Goldsithney New Builds — local questions answered.
- 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. In Goldsithney specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
