Building Regs Perranuthnoe: TR20 planning, West Cornwall fabric
Building regulation drawings in Cornwall, drawn properly. Approved planning gets you permission to build — a complete building regs package is what gets you a building you can actually live in: 1:50 plans, 1:10 details, structural coordination and a specification a Cornish builder can price and build from without guesswork. A TR20 site visit comes before a Perranuthnoe sketch, every time — Perranuthnoe is a small AONB cliff-top village between Marazion and Praa Sands, with a sandy cove, twelfth-century church and a tight, well-preserved Conservation Area at its centre, with a building stock that leans toward 1960s coastal bungalows and Edwardian villas.
Perranuthnoe sits in West Cornwall — covering TR20 from Marazion, Goldsithney outward.

Why Perranuthnoe is its own job.
Conservation Area covers the village core and church; AONB extends across the parish. Isolated dwelling policy applies in the open countryside between settlements. That sets the scene before any design work begins. For building regulations package specifically, parts of Perranuthnoe 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 Perranuthnoe 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. It's the kind of detail that decides whether a Perranuthnoe application gets approved at eight weeks or stalls in committee. The 1960s coastal bungalows that dominate Perranuthnoe (and continue out toward Praa Sands) set the tone for any building regulations package scheme here.
Planning note
Building regulations are a separate consent track from planning. Drawing them properly upfront is the cheapest insurance you'll buy on the project.
What we focus on
Building Regs considerations specific to Perranuthnoe.
01
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
02
Cornish exposure ratings are among the worst in the country; wind-driven rain detailing matters more here than in most of the UK.
03
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
04
Part L and the Future Homes Standard route now drives a meaningful share of the build cost; getting the U-values and air-tightness strategy right at design stage saves money on site.
Our process
How a Perranuthnoe building regulations package project runs.
Step 1
Design freeze
We confirm the planning-approved scheme as the basis for technical design.
Step 2
Structural coordination
Engineer's input on foundations, beams, lintels and steelwork is integrated into the drawings.
Step 3
Detailing
Construction details drawn at 1:10 for every junction that matters.
Step 4
Specification
Materials, U-values, finishes and workmanship written up so the builder can price accurately.
Step 5
Submission
Full Plans submission to building control with fee handling and query response through to completion certificate.
Most regs packages take three to six weeks once planning is approved, depending on structural complexity and engineer turnaround.

Perranuthnoe Building Regs — local questions answered.
- Do I really need building regs drawings if I have planning?
- Yes — they cover completely different things. Planning controls how the building looks and where it sits; building regs control how it's actually built and whether it complies with current safety, energy and accessibility law. In Perranuthnoe specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Do you coordinate with a structural engineer?
- Yes — every project that needs steel, timber or masonry calculations is coordinated in-house with a Cornish structural engineer we work with regularly.
- Who do you submit to in Cornwall?
- Either Cornwall Council building control or one of the Approved Inspectors active in the county. We're happy to recommend, but the choice is yours.
- What happens if something changes on site?
- Site queries are part of the job. We respond directly to the builder during construction, issue revised details where needed and keep building control informed if the change is material.
- Can the builder work without building regs drawings?
- They can — and many do — but the cost gets recovered later in variations, mistakes and slower building control sign-off. A proper regs pack typically pays for itself several times over on anything beyond the smallest job.
