Building Regs that reads Long Rock properly
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 Long Rock version of this work has its own character — Long Rock is a coastal village on Mounts Bay between Penzance and Marazion, much expanded by twentieth-century development along the A30 and railway corridor, with a building stock that leans toward post-war estates and converted railway-era buildings.
Long Rock sits in West Cornwall — covering TR20 from Marazion, Penzance, Gulval outward.

Coastal exposure driving fixing, render and joinery spec
Who this is for
Long Rock 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 Long Rock is its own job.
Around Long Rock (TR20), outside Conservation Area and AONB but the seafront is environmentally sensitive; flood zone constraints affect properties south of the railway line. Ludgvan parish policy applies. For building regulations package specifically, coastal salt-laden air around Long Rock drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Reading Long Rock properly up front saves more time than any drawing tool ever will. Most of our building regulations package work in Long Rock lands on post-war estates, with detailing that has to nod to the wider Gulval 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 Long Rock.
01
Approved Inspectors and Cornwall Council building control both work in the county; choice of inspector affects how queries are handled.
02
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
03
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
04
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 Long Rock 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
Long Rock Building Regs — local questions answered.
- Who do you submit to in Long Rock?
- 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. In Long Rock specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
- 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.
Long Rock is part of Marazion
Long Rock sits inside the Marazion catchment — we cover both as one building regulations package territory.
See Building Regs in Marazion →Local proof — We typically have one or two building regulations package jobs live in the TR20 area at any time, so the local planning officers know our drawings on sight.
