How a Treyarnon building regulations package project runs.
Step 1

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.
Local proof — Most Treyarnon homeowners come to us after a building regulations package quote elsewhere felt vague on planning — we lead with feasibility instead.

Building Regs considerations specific to Treyarnon.
01
Cornish exposure ratings are among the worst in the country; wind-driven rain detailing matters more here than in most of the UK.
02
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
03
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
04
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
Local context
Why Treyarnon is its own job.
In Treyarnon the planning picture is specific: planning scrutiny often focuses on visual impact, occupancy, parking, overlooking and whether replacement buildings respect the coastal edge. For building regulations package specifically, 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 Treyarnon drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a Treyarnon (PL28) project different from a generic Cornwall scheme — and is the whole reason we work this way. On coastal bungalows in particular — the kind you'll also find toward Harlyn — the building regulations package brief always has to read the existing fabric first.
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.

FAQs
Treyarnon Building Regs — local questions answered.
- 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. In Treyarnon specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
- 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.
