Eco new builds in Looe — sustainable spec that stacks up
An eco new-build in Looe 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 PL13 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. Anchor any Looe new build in the local fabric and the rest follows — Looe is a working fishing town and seaside resort split by the Looe River into East and West Looe, with one of Cornwall's largest fishing fleets and a substantial Conservation Area covering both halves, with a building stock that leans toward medieval and Georgian harbour cottages and modern coastal homes at Hannafore.
Looe sits in East Cornwall — just off the A38; covering PL13 from Polperro, Duloe, Talland outward.

Who this is for
In Looe 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.
Local watch-list
The PL13 constraints that shape a new build brief.
Watch #1
Conservation Area controls on materials, window proportions and roof form through central Looe
Watch #2
AONB landscape-impact testing on anything read in long views across East Cornwall
Watch #3
Exposure detailing on medieval and Georgian harbour cottages — fixings, render systems and joinery specified for salt-laden air
Watch #4
Party Wall notices and shallow roof voids typical of medieval and Georgian harbour cottages in the PL13 district
Local proof — Our East Cornwall workload means a Looe new build project never has to wait for an out-of-county team to drive down.

Looe New Builds — local questions answered.
- Is timber-frame or block best for eco in Looe?
- 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 Looe?
- 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.
- 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. In Looe 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.
- We live in the house. Can a new build in Looe 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 Looe are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.

Who this is for
Why this page exists, and who it is for
- Drawings, planning and building regulations are all produced in-house, so a new build enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Applications for Looe are handled through Cornwall Council, with Liskeard the nearest planning office we deal with regularly.
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.

Follow the chain: survey, drawings, build
We cover Looe and the wider PL13 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 Looe?
Both routes are open on a PL13 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Looe 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 PL13 scope, not as one opaque figure
Scope
What we can draw, survey and build around Looe
These stages can be bought separately. Most PL13 projects use three of them.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Local context
Why Looe is its own job.
Locally, conservation Area covers both East and West Looe historic cores; AONB across the wider parish. Flood Zone 3 designation affects substantial parts of the harbour and town. For new build specifically, parts of Looe 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 Looe drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Which is why we scope Looe projects parish-up, not template-down — the PL13 context shapes the design from day one. Whether the project is on medieval and Georgian harbour cottages in the centre or further out toward Polperro, the new build response is locally tuned. 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. Salt air and prevailing wind change specification long before they change planning. We tend to draw weathering details in full, then check whether coastal or AONB policy narrows the design options for this address.
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 Looe.
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
Off-grid services — package treatment plants, borehole supply, off-mains gas — are common on rural Cornish plots and need designing, not assuming.
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
Cornwall's housing policy increasingly favours principal residence and replacement dwelling schemes over open-market new builds in some parishes.
Our process
How a Looe 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 fabric
Why Looe homeowners pick a local studio for new build.
Building stock
Across Looe (PL13) we work on medieval and Georgian harbour cottages, Victorian guesthouses, Edwardian villas above the town, modern coastal homes at Hannafore. Each stock type drives a different new build response — medieval and Georgian harbour cottages in particular needs careful detailing here.
Parish & policy
Looe is its own town in East Cornwall, with planning history that's specific to the PL13 catchment.
Coverage
We cover PL13 from our studio, with regular new build jobs also running in East Cornwall. Most Looe site visits get booked within the same week.
What does a first Looe consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL13 plot and follow up with a written feasibility note inside a week — no obligation either way.

Not every Looe 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.
