Eco new builds in Falmouth — sustainable spec that stacks up
An eco new-build in Falmouth 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 TR11 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. Reading Falmouth on the ground is half of the new build job — Falmouth is a deep-water harbour town built around one of the world's largest natural harbours, with a thriving art college, Maritime Museum and a Victorian and Edwardian seafront, with a building stock that leans toward Victorian terraces and post-war suburbs at Trescobeas.
Falmouth sits in South Cornwall — just off the A39; with Truro the closest city; covering TR11 from Penryn, Mylor Bridge, Mawnan Smith outward.

Who this is for
In Falmouth the new build brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Scope
The parts of the job we can take on in Falmouth
Not every project needs every stage. On a Falmouth job we scope to what the site and the consent route actually require.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Commercial drawings
Change of use, fit-out and access documentation for Class E and mixed-use premises.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Who this is for
What we can genuinely back up in Falmouth
- Design and build are offered from the same studio, which means the person answering your Falmouth questions has seen the detail built.
- Commercial and mixed-use work in Falmouth tends to sit around Falmouth Docks.
- Sites we know on the ground here include the area around Discovery Quay and Gyllyngvase Beach.
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
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.

We cover Falmouth and the wider TR11 district directly. New Builds enquiries here are common enough that we know the constraints before the first visit.
Page purpose
Drawings only, or drawings through to handover in Falmouth?
Both routes are open on a TR11 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Falmouth 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
Local context
Why Falmouth is its own job.
Around Falmouth (TR11), falmouth has multiple Conservation Areas — Town Centre, Greenbank, Penryn River and Pendennis — each with its own character appraisal. Article 4 directions remove some permitted development rights in the Town Centre and seafront zones; HMO licensing is a separate active policy area. For new build specifically, parts of Falmouth 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 Falmouth drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Reading Falmouth properly up front saves more time than any drawing tool ever will. Most of our new build work in Falmouth lands on Victorian terraces, with detailing that has to nod to the wider Budock Water streetscape. On older stock, the practical constraint is usually joinery, render and roof line rather than the extension itself. We draw those details out early so a new build submission is not sent back for missing information. Confirm listing status with the local planning authority before assuming permitted development. Exposure is the real design driver near the water: wind-driven rain, salt and driving damp push detailing towards better weathering, sheltered openings and robust fixings. Where an AONB or coastal policy applies, visual impact usually carries more weight than size.
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 Falmouth.
01
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
02
Replacement dwellings have specific volumetric tests — getting the ratio between existing footprint and proposed floor area right is the difference between approval and refusal.
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 Falmouth 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
Falmouth New Builds — local questions answered.
- Is timber-frame or block best for eco in Falmouth?
- 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 Falmouth?
- 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.
- 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. In Falmouth specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
Local proof — Our South Cornwall workload means a Falmouth new build project never has to wait for an out-of-county team to drive down.

Not every Falmouth 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.
