New Builds for Mithian Downs (TR5)
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. Working in Mithian Downs means starting from the TR5 context — Mithian Downs is a small rural hamlet in the TR5 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and converted barns.
Mithian Downs sits in North Cornwall — covering TR5 from St Agnes, Mount Hawke, Trevellas outward.

New Builds considerations specific to Mithian Downs.
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 Mithian Downs is its own job.
In Mithian Downs the planning picture is specific: the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. That local reading is what makes a Mithian Downs (TR5) project different from a generic Cornwall scheme — and is the whole reason we work this way. On cottages in particular — the kind you'll also find toward Mithian — 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
Mithian Downs 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 Mithian Downs specifically, we'd start by checking AONB landscape sensitivity 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 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.
- 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.
