Passivhaus architect in Bodmin — low-energy homes done properly

Passivhaus in Bodmin is not a marketing sticker — it's a numbers-driven design method that requires orientation modelling, air-tightness planning and MVHR sizing from the first sketch. On rural plots in PL31, the shading from mature trees is the first variable we test in PHPP. 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. A PL31 site visit comes before a Bodmin sketch, every time — Bodmin is the historic county town and sits on the south-western edge of Bodmin Moor, with a substantial fifteenth-century church, the Beacon viewpoint and a Conservation Area covering the medieval core, with a building stock that leans toward post-war estates and Victorian terraces.

Bodmin sits in East Cornwall — just off the A30; with Truro the closest city; covering PL31 from Lanivet, Blisland, Cardinham outward.

FAQs

Bodmin New Builds — local questions answered.

Is Passivhaus worth it in Bodmin?
Financially, the 8–15% build premium pays back in 15–20 years at current energy prices. Comfort-wise, the payback is immediate. On new-builds in PL31, we recommend it on any plot with reasonable orientation.
Do you produce full PHPP models?
Yes, or we work alongside a certified PHPP consultant. Either route lands the same result — a fully modelled, air-tightness-tested certified Passivhaus.
What's the cost difference vs a standard new build?
£3,600–£4,800/m² for Passivhaus vs £3,000–£4,000/m² for a well-insulated standard build. Premium is smaller than most people expect.
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 Bodmin specifically, we'd start by checking the Conservation Area boundary 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.
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.

Local context

Why Bodmin is its own job.

Cornwall Council's lens on Bodmin is consistent: conservation Area covers the historic streets including Fore Street and Honey Street. Bodmin Moor (separately AONB) lies to the east; Bodmin Town Council operates active input on town centre regeneration. For new build specifically, parts of Bodmin sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. That's why we treat every Bodmin project as a PL31-area job first — not a generic Cornwall job with a postcode bolted on. The post-war estates that dominate Bodmin (and continue out toward Cardinham) set the tone for any new build scheme here.

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 Bodmin.

  • 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

    Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.

  • 03

    Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.

  • 04

    AONB and Heritage Coast designations apply to large stretches of the county; isolated new builds outside settlement boundaries face a much higher policy bar.
