Altarnun building regs — a East Cornwall studio
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. In Altarnun, that work is shaped by the place itself — Altarnun is a moorland-edge hamlet in the PL15 area, where exposed weather, narrow lanes and rural character set the brief, with a building stock that leans toward farm buildings and converted barns.
Altarnun sits in East Cornwall — covering PL15 from Launceston, Warbstow, North Petherwin outward.

Common Altarnun pitfalls we plan around.
Watch #1
Conservation Area material and fenestration controls in central Altarnun
Watch #2
Tighter Local Plan tests on isolated rural dwellings
Local proof — Most Altarnun building regulations package clients we work with are second-time builders — they've seen the templated approach fail once already.

Altarnun Building Regs — local questions answered.
- 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. In Altarnun specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- Building Notice or Full Plans?
- Full Plans gives you a formal approval before work starts and a clean paper trail for resale. Building Notice is faster and cheaper up front but less protective. We default to Full Plans for anything other than very simple work.
- 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.
- 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.
Local context
Why Altarnun is its own job.
The planning backdrop in East Cornwall is real, not abstract: rural policy, landscape impact and services such as drainage are usually the key constraints, especially outside settlement boundaries. For building regulations package specifically, parts of Altarnun sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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. Treat the PL15 parish brief as the design brief and the Altarnun application has somewhere to land. Whether the project is on farm buildings in the centre or further out toward Launceston, the building regulations package response is locally tuned.
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 Altarnun.
01
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.
02
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
03
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
04
Cornish exposure ratings are among the worst in the country; wind-driven rain detailing matters more here than in most of the UK.
Our process
How a Altarnun 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.
