Design, planning and build for Tresillian 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. Every Tresillian project we take on begins with reading the local context — Tresillian is a village east of Truro at the head of the Tresillian River, AONB-designated, with a Conservation Area covering the village core, with a building stock that leans toward Edwardian houses and Victorian villas.
Tresillian sits in Mid Cornwall — covering TR2 from Truro, Tregony, Ladock outward.
- Conservation Area
- Cornwall AONB
- Coastal exposure zone
- Rural / open-countryside policy area
- ✓ 30+ years of Cornwall Council approvals
- ✓ Plain-English feasibility before any drawings
- ✓ Fixed-fee planning packages, no surprise invoices
- ✓ Measured-survey accuracy from day one
Local proof — Our Mid Cornwall workload means a Tresillian building regulations package project never has to wait for an out-of-county team to drive down.

Why Tresillian is its own job.
Cornwall Council's lens on Tresillian is consistent: conservation Area covers the village; AONB across the parish. Riverside ecology and views shape applications on the southern edge. For building regulations package specifically, parts of Tresillian 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 Tresillian 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. That's why we treat every Tresillian project as a TR2-area job first — not a generic Cornwall job with a postcode bolted on. The Edwardian houses that dominate Tresillian (and continue out toward Ladock) 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 Tresillian.
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
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
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 Tresillian 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.
Local fabric
Choosing a building regulations package team that actually knows TR2.
Building stock
Across Tresillian (TR2) we work on traditional cob and granite cottages, Victorian villas, Edwardian houses, post-war bungalows, modern AONB-sensitive infill. Each stock type drives a different building regulations package response — Edwardian houses in particular needs careful detailing here.
Parish & policy
Tresillian sits in the parish of St Erme, which matters for how parish-level consultation lands on a building regulations package application.

Tresillian Building Regs — local questions answered.
- 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. In Tresillian 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.
- 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.
Tresillian is part of Truro
Tresillian sits inside the Truro catchment — we cover both as one building regulations package territory.
