Design, planning and build for Treliske building regulations package
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 TR1 site visit comes before a Treliske sketch, every time — Treliske is a town-edge neighbourhood in the TR1 area, where modern housing, larger gardens and edge-of-settlement plots create practical development opportunities, with a building stock that leans toward modern estates and infill plots.
Treliske sits in Mid Cornwall — covering TR1 from Truro, St Michael Penkivel, Calenick outward.
- Rural / open-countryside policy area
- ✓ 30+ years of Cornwall Council approvals
- ✓ Plain-English feasibility before any drawings
- ✓ Local to Mid Cornwall — not a national franchise
- ✓ Same team on paper as on site
Local proof — We typically have one or two building regulations package jobs live in the TR1 area at any time, so the local planning officers know our drawings on sight.

Why Treliske is its own job.
Cornwall Council's lens on Treliske is consistent: neighbour amenity, highways, drainage and the transition from built-up edge to countryside are usually the planning pressure points. For building regulations package specifically, 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. That's why we treat every Treliske project as a TR1-area job first — not a generic Cornwall job with a postcode bolted on. The modern estates that dominate Treliske (and continue out toward Calenick) 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 Treliske.
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
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
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
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
Our process
How a Treliske 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.

Treliske 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 Treliske specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
Treliske is part of Truro
Treliske sits inside the Truro catchment — we cover both as one building regulations package territory.
