Trelowarren new build — feasibility first, drawings second
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. In Trelowarren, that work is shaped by the place itself — Trelowarren is an estate-influenced village in the TR12 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward estate cottages and converted outbuildings.
Trelowarren sits in Lizard Peninsula — just off the A394; covering TR12 from Helston, Breage, Ashton outward.

Who this is for
In Trelowarren 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.
Local watch-list
Trelowarren-specific issues we screen on the first visit.
Watch #1
AONB landscape-impact testing on anything read in long views across Lizard Peninsula
Watch #2
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Trelowarren
Watch #3
Party Wall notices and shallow roof voids typical of estate cottages in the TR12 district
Watch #4
Trussed roofs and shallow foundations in the later TR12 estates, which change the structural strategy
Local proof — Our Lizard Peninsula workload means a Trelowarren new build project never has to wait for an out-of-county team to drive down.

Trelowarren 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 Trelowarren specifically, we'd start by checking AONB landscape sensitivity 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.
- We live in the house. Can a new build in Trelowarren 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 Trelowarren 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.
- 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.

Who this is for
Why this page exists, and who it is for
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Applications for Trelowarren are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
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.

Follow the chain: survey, drawings, build
Trelowarren is covered from our Helston run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
Drawings only, or drawings through to handover in Trelowarren?
Both routes are open on a TR12 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Trelowarren 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 TR12 scope, not as one opaque figure

Written justification where designation makes the design case as important as the drawing.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
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.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Local context
Why Trelowarren is its own job.
Locally, landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. For new build specifically, 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; 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. Which is why we scope Trelowarren projects parish-up, not template-down — the TR12 context shapes the design from day one. Whether the project is on estate cottages in the centre or further out toward Helston, the new build response is locally tuned.
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 Trelowarren.
01
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
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
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
04
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
Our process
How a Trelowarren 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 fabric
Choosing a new build team that actually knows TR12.
Building stock
Across Trelowarren (TR12) we work on estate cottages, farm buildings, detached homes, converted outbuildings, small infill plots. Each stock type drives a different new build response — estate cottages in particular needs careful detailing here.
Parish & policy
Trelowarren sits in the parish of Trelowarren, which matters for how parish-level consultation lands on a new build application.

We cover TR12 from our studio, with regular new build jobs also running in Helston, Breage, Ashton. Most Trelowarren site visits get booked within the same week.
What does a first Trelowarren consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR12 plot and follow up with a written feasibility note inside a week — no obligation either way.
