Building Regulations Drawings in Trevellas
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. The Trevellas version of this work has its own character — Trevellas is a coastal village in the TR5 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward bungalows and granite cottages.
Trevellas sits in North Cornwall — covering TR5 from St Agnes, Mount Hawke, Mithian outward.

Who this is for
Trevellas runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every building regulations package enquiry from the use-class up.
Local context
Why Trevellas is its own job.
Coastal setting and landscape sensitivity mean rooflines, glazing, drainage and external materials need careful handling from the first sketch. 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; coastal salt-laden air around Trevellas drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. So every Trevellas job runs as a TR5-specific piece of work — local policy, local fabric, local builders. Most of our building regulations package work in Trevellas lands on bungalows, with detailing that has to nod to the wider Mount Hawke streetscape.
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 Trevellas.
01
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
02
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
03
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.
04
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
Our process
How a Trevellas 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.
FAQs
Trevellas Building Regs — local questions answered.
- 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. In Trevellas specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
- 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.
