Eco new builds in Tintagel — sustainable spec that stacks up
An eco new-build in Tintagel doesn't have to be Passivhaus-certified to make sense. Timber-frame construction, wood-fibre insulation, triple glazing and a properly sized air-source heat pump get you 85–90% of Passivhaus performance for a build premium under 6%. On PL34 plots, this is the pragmatic middle ground. 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. Tintagel sits in North Cornwall, and that geography ends up in the drawings — Tintagel sits above a famously dramatic stretch of north coast cliff, with the medieval and Arthurian-associated castle on its headland and a Conservation Area covering the village centre, with a building stock that leans toward modern coastal new builds and replacements and Victorian guesthouses.
Tintagel sits in North Cornwall — covering PL34 from Boscastle, Delabole outward.

Who this is for
Tintagel runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every new build enquiry from the use-class up.
Local context
Why Tintagel is its own job.
Two things shape a Tintagel application: parish character and policy. On policy — conservation Area covers the village; AONB and Heritage Coast across the parish. English Heritage and historic landscape considerations weigh on village-edge schemes. For new build specifically, parts of Tintagel 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 Tintagel 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. Get that local reading right and the rest of the Tintagel programme tends to run on time. On modern coastal new builds and replacements in particular — the kind you'll also find toward Boscastle — 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.
What we focus on
New Builds considerations specific to Tintagel.
01
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
04
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
Our process
How a Tintagel 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.
FAQs
Tintagel New Builds — local questions answered.
- Is timber-frame or block best for eco in Tintagel?
- Timber-frame nearly every time — lower embodied carbon, faster on-site programme, better air-tightness detailing. The exception is exposed coastal plots where masonry may still win on maintenance.
- What eco heating works in Tintagel?
- Air-source heat pump with underfloor heating downstairs, radiators upstairs. Ground-source only makes sense on plots with borehole space. PV on the roof pays back in 9–12 years at current rates.
- Does eco spec add much cost?
- £3,200–£4,200/m² for sensible eco spec vs £3,000–£4,000 standard. Under 6% premium for major improvements in comfort and running cost.
- 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 Tintagel 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.

Not every Tintagel eco home needs full Passivhaus certification — sensibly specified timber-frame with the right envelope gets most of the benefit for a fraction of the premium.
