Planning permission versus building regulations in Carbis Bay, explained plainly
These two get mixed up constantly, and the confusion costs people money. Planning permission is about whether a proposal is acceptable in its setting: its size, its appearance, its effect on neighbours and on the character of Carbis Bay. Building regulations are about the construction itself: structure, fire safety, insulation, ventilation, drainage and access. You can have one without the other, and plenty of Carbis Bay projects need both. 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. In Carbis Bay, that work is shaped by the place itself — Carbis Bay is the residential coastal suburb of St Ives, climbing up the cliffs above one of the calmest beaches on the north coast and built largely between 1900 and 1970, with a building stock that leans toward Edwardian and 1930s detached villas and modern coastal architect-designed homes.
Carbis Bay sits in West Cornwall — just off the A3074; with Truro the closest city; 1 miles from St Ives.

Page purpose
What you actually get on a Carbis Bay building regulations package drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR26 address, not a build contract. For most Carbis Bay householders that means a measured survey, an honest feasibility view, then the drawings the council and your builder both need.
- Measured survey and existing drawings before any proposal is drawn
- A written planning route for the TR26 address, including whether permitted development is realistically available
- Proposed plans, elevations and site plan at the scales the authority expects
- Submission and validation handling, plus responses to officer queries
Scope
What we can draw, survey and build around Carbis Bay
Not every project needs every stage. On a Carbis Bay job we scope to what the site and the consent route actually require.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.

Who this is for
Why this page exists, and who it is for
- Sites we know on the ground here include the area around the beach and Carbis Bay Hotel.
- Design and build are offered from the same studio, which means the person answering your Carbis Bay questions has seen the detail built.
- Applications for Carbis Bay are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
- Drawings, planning and building regulations are all produced in-house, so a building regulations package enquiry does not get passed between firms.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
What we focus on
Building Regs considerations specific to Carbis Bay.
01
Granite walls, traditional cob, slate-hung elevations and rubble construction all need different building regs detailing than standard masonry.
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
Coastal sites need explicit material and fixings choices in the spec — stainless or non-ferrous fixings, salt-resistant cladding and breathable build-ups.
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.

Local context
Why Carbis Bay is its own job.
Locally, aONB designation covers the whole village; coastal views and cumulative cliffside development are weighed in most applications. Carbis Bay sits inside St Ives parish's principal residence policy area. 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; coastal salt-laden air around Carbis Bay drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Which is why we scope Carbis Bay projects parish-up, not template-down — the TR26 context shapes the design from day one. Whether the project is on Edwardian and 1930s detached villas in the centre or further out toward St Ives, the building regulations package response is locally tuned. Exposure is the real design driver near the water: wind-driven rain, salt and driving damp push detailing towards better weathering, sheltered openings and robust fixings. Where an AONB or coastal policy applies, visual impact usually carries more weight than size.
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.

How a Carbis Bay 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
Carbis Bay Building Regs — local questions answered.
- Can I have planning permission but fail building regulations?
- Yes, and it happens. A scheme can be perfectly acceptable in planning terms and still need reworking to satisfy structure, insulation or escape requirements. That is why the technical drawings come after the planning drawings.
- Which comes first?
- Usually planning, because the approved scheme sets the shape the technical package then has to make work. On permitted development projects there is no planning stage, so the building regulation package is the whole job.
- Do both need separate drawings?
- Yes. Planning drawings are about form and context and are typically at 1:100 and 1:50. Building regulation drawings are about construction and go down to 1:10 or finer at the junctions.
- Who decides each one in Carbis Bay?
- Planning is determined by the local planning authority. Building regulations are assessed by a building control body, which may be the local authority team or an approved inspector. They are separate processes with separate fees and timescales.
- We live in the house. Can a building regulations package in Carbis Bay be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Carbis Bay are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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 Carbis Bay specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
