New Builds that reads Mawnan Smith properly
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 Mawnan Smith version of this work has its own character — Mawnan Smith is an AONB village south of Falmouth between the Helford River and Maenporth Beach, with a strong period property market and a tight Conservation Area at its centre, with a building stock that leans toward Edwardian houses and high-end modern architect builds.
Mawnan Smith sits in South Cornwall — just off the A39; with Truro the closest city; 3 miles from Falmouth.

Our process
How a Mawnan Smith 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 South Cornwall workload means a Mawnan Smith new build project never has to wait for an out-of-county team to drive down.

Other work we do around Mawnan Smith
Mawnan Smith works as a hub for us: the same new build team covers Mawnan, Durgan and the surrounding TR11 villages, so a site visit here often takes in more than one address.
Page purpose
Drawings only, or drawings through to handover in Mawnan Smith?
Both routes are open on a TR11 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Mawnan Smith 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 TR11 scope, not as one opaque figure

What we focus on
New Builds considerations specific to Mawnan Smith.
01
AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
02
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
03
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
04
Self-build CIL exemption requires the right documentation in the right order; missing a step costs five-figure sums.
Local context
Why Mawnan Smith is its own job.
Around Mawnan Smith (TR11), conservation Area covers the village core; AONB across the parish. Helford River views and ecology constraints shape applications on the southern edge. For new build specifically, parts of Mawnan Smith 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 Mawnan Smith drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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. Reading Mawnan Smith properly up front saves more time than any drawing tool ever will. Most of our new build work in Mawnan Smith lands on Edwardian houses, with detailing that has to nod to the wider Maenporth streetscape.
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
Mawnan Smith 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 Mawnan Smith specifically, we'd start by checking the Conservation Area boundary 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.
- We live in the house. Can a new build in Mawnan Smith 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 Mawnan Smith are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
