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 — just off the A30; covering TR20 from Marazion, Perranuthnoe outward.

Page purpose
Drawings only, or drawings through to handover in Goldsithney?
Both routes are open on a TR20 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Goldsithney 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 TR20 scope, not as one opaque figure

What we focus on
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 Ashton — 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.

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