Building Regulations Drawings in Probus
Approved planning gets you permission to build. Building regulations drawings are what gets you a building you can actually live in — drawn properly, they shorten the build, save the builder time and keep building control on side. In Probus, that work is shaped by the place itself — Probus is a substantial inland village between Truro and St Austell, with the tallest church tower in Cornwall and a Conservation Area covering the village centre, with a building stock that leans toward traditional cob and granite cottages and Victorian terraces.

Local context
Why Probus is its own job.
Conservation Area covers the village core including the church. Tregothnan Estate (the largest private estate in Cornwall) lies to the south and shapes some adjacent applications. For building regulations package specifically, parts of Probus 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. That's why we treat every Probus project as a TR2-area job first — not a generic Cornwall job with a postcode bolted on.
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 Probus.
01
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
02
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.
03
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 Probus 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
Probus Building Regs — common questions.
- 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. In Probus specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
