Planning approved in Porthleven, so what happens now?
An approval notice feels like the finish line and is really the starting gun. Before anyone digs in Porthleven, three things need dealing with: the conditions attached to the consent, the building regulation package, and the structural design. Conditions in particular catch people out, because some of them are pre-commencement, which means work started before they are discharged is technically unauthorised. Once drawings are approved, the build is the bit that decides whether you get the home you imagined or a frustrating compromise. We deliver projects on a single contract — design, drawings, approvals and construction — so the team that drew it is the team that builds it. A TR13 site visit comes before a Porthleven sketch, every time — Porthleven is the most southerly port on mainland Britain, AONB-designated, with a working harbour, dramatic winter swell and a terraced cliff-edge of Victorian cottages, with a building stock that leans toward modern coastal homes set back from the cliff and Victorian terraces.
Porthleven sits in West Cornwall — just off the A30; covering TR13 from Helston, Breage, Ashton outward.

Who this is for
In Porthleven the full build package 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
Local snags worth knowing before drawing a Porthleven full build package.
Watch #1
Conservation Area controls on materials, window proportions and roof form through central Porthleven
Watch #2
AONB landscape-impact testing on anything read in long views across West Cornwall
Watch #3
Exposure detailing on fishermen's cottages above the harbour — fixings, render systems and joinery specified for salt-laden air
Watch #4
Party Wall notices and shallow roof voids typical of fishermen's cottages above the harbour in the TR13 district
Local proof — Our West Cornwall workload means a Porthleven full build package project never has to wait for an out-of-county team to drive down.

Porthleven Full Build — local questions answered.
- What is a pre-commencement condition?
- A condition that has to be discharged before any work begins, commonly covering materials, drainage strategy, ecology or construction management. Starting work before discharging one can invalidate the permission, so it is worth checking the notice line by line.
- How long does planning permission last?
- Permissions normally carry a time limit within which work must begin, stated on the decision notice itself. Check the wording on yours rather than relying on a general rule.
- Do I need new drawings after approval?
- Yes. The approved drawings show the scheme; the building regulation and construction package shows how it is built. That second set is what the builder and building control work from.
- When should I get prices?
- Once the technical drawings exist. Pricing from planning drawings alone produces quotes that are not comparable, because each builder is filling in the missing detail differently.
- We live in the house. Can a full build package in Porthleven 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 Porthleven are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- What guarantees and aftercare do you offer?
- Standard twelve-month defects period, plus product and workmanship warranties on relevant elements. We're a Cornish business — you'll still find us in the same studio in five years' time. In Porthleven specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Fixed price or open book?
- Both. Fixed price suits well-defined projects with clear specs; open book suits renovations and listed work where the unknowns only reveal themselves once you start opening things up. We'll recommend the right route.

Page purpose
How a Porthleven build actually runs
This is delivery, not paperwork. The value here is programme, sequencing and a single point of responsibility for a TR13 site. In Porthleven that usually means access, storage and neighbour management get planned before the first delivery arrives.
- Site set-up planned around Porthleven access, parking and delivery constraints
- One programme covering trades, inspections and building control sign-off
- Materials specified for local exposure, not a generic national spec
- Weekly progress contact so decisions never hold up the programme
Scope
Where our work starts and stops on a TR13 project
Not every project needs every stage. On a Porthleven job we scope to what the site and the consent route actually require.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Who this is for
Our footing in West Cornwall
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a full build package enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Porthleven questions has seen the detail built.
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.

Local context
Why Porthleven is its own job.
Cornwall Council's lens on Porthleven is consistent: porthleven Conservation Area covers the harbour and most residential streets; AONB designation extends across the whole parish. Coastal exposure and views from the South West Coast Path are routine planning considerations. For full build package specifically, parts of Porthleven 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 Porthleven drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Porthleven project as a TR13-area job first — not a generic Cornwall job with a postcode bolted on. The modern coastal homes set back from the cliff that dominate Porthleven (and continue out toward Breage) set the tone for any full build package scheme here. 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 full build package 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
Build delivery doesn't need planning, but planning conditions often dictate site setup, materials and working hours — we read every condition and build the programme around them.
What we focus on
Full Build considerations specific to Porthleven.
01
Weather windows on Cornish coastal sites are short — getting the building watertight before autumn matters more here than in central England.
02
Material lead times to Cornwall are longer than the M5 corridor; sequencing orders early protects the build programme.
03
Off-grid sites need their own water, drainage and power solutions designed and procured rather than assumed.
04
Cornish trades are a tight community; using contractors who've worked together before saves weeks on programme and arguments on site.

How a Porthleven full build package project runs.
Step 1
Pre-construction
Programme, procurement, contractor briefing and site setup.

Superstructure
Frame, roof, glazing — getting the building watertight.
Step 4
First and second fix

Step 5
Snag and handover
Final inspection, building control sign-off, handover pack and aftercare.
Full builds run from twelve weeks for small extensions to eighteen months for new build family homes.
Local fabric
Why Porthleven homeowners pick a local studio for full build package.
Building stock
Across Porthleven (TR13) we work on fishermen's cottages above the harbour, Victorian terraces, modern coastal homes set back from the cliff, converted lofts and warehouses. Each stock type drives a different full build package response — modern coastal homes set back from the cliff in particular needs careful detailing here.
