Lower Boscaswell 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. On a Lower Boscaswell site, the brief always meets the place — Lower Boscaswell is a former mining settlement in the TR19 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward granite terraces and post-war estates.
Lower Boscaswell sits in Penwith — just off the A30; covering TR19 from Pendeen, Morvah, Trewellard outward.

Lower Boscaswell 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 Lower Boscaswell specifically, we'd start by checking AONB landscape sensitivity 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 Lower Boscaswell 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 Lower Boscaswell are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.

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 Lower Boscaswell 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
Lower Boscaswell is covered from our Pendeen 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 Lower Boscaswell?
Both routes are open on a TR19 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Lower Boscaswell 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 TR19 scope, not as one opaque figure
Scope
What we can draw, survey and build around Lower Boscaswell
Not every project needs every stage. On a Lower Boscaswell job we scope to what the site and the consent route actually require.
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.
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.
Local context
Why Lower Boscaswell is its own job.
Locally, mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; 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 Lower Boscaswell projects parish-up, not template-down — the TR19 context shapes the design from day one. Whether the project is on granite terraces in the centre or further out toward Pendeen, 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 Lower Boscaswell.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
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.

How a Lower Boscaswell 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 TR19.

Across Lower Boscaswell (TR19) we work on miners cottages, granite terraces, chapel conversions, workers cottages, post-war estates. Each stock type drives a different new build response — granite terraces in particular needs careful detailing here.
