Structural Calculations Carbis Bay: TR26 planning, West Cornwall fabric
Whenever a wall comes out, a roof is opened up or a new opening is formed, building control will want calculations showing that what is left holds up what is above it. We coordinate that work alongside the drawings so the beam on the calculation sheet is the beam on the drawing. A TR26 site visit comes before a Carbis Bay sketch, every time — 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 1960s estate housing and post-war bungalows.
Carbis Bay sits in West Cornwall — just off the A3074; with Truro the closest city; 1 miles from St Ives.

Our process
How a Carbis Bay structural calculations project runs.
Step 1
Establish the structure
A survey records what is load bearing, what spans where and what sits above.
Step 2
Brief the engineer
Drawings and loading assumptions are issued so calculations are done against real geometry.
Step 3
Calculate
Beams, bearings, foundations and stability are sized and checked.
Step 4
Coordinate onto drawings
Sizes and details come back onto the construction package.
Step 5
Submit and build
Building control receives one coordinated set and the builder installs what was calculated.
Work ranges from a single beam over a knocked through kitchen to a full structural scheme for a new build or a barn conversion.
Local proof — Most Carbis Bay structural calculations clients we work with are second-time builders — they've seen the templated approach fail once already.

What you actually get on a Carbis Bay structural calculations 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
Where our work starts and stops on a TR26 project
Not every project needs every stage. On a Carbis Bay job we scope to what the site and the consent route actually require.
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.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Who this is for
Our footing in West Cornwall
- Drawings, planning and building regulations are all produced in-house, so a structural calculations enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- 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.
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
Structural Calculations considerations specific to Carbis Bay.
01
Where a party wall is affected, structural information is also what the neighbour's surveyor will ask to see.
02
Exposed sites carry higher wind loading, which affects roof fixings, gable restraint and large areas of glazing.
03
Ground conditions vary sharply across Cornwall, from granite close to the surface to soft made ground near estuaries, and foundation design follows the ground, not the pattern book.
04
Loft conversions almost always need new floor joists and a structural opening for the stair, both of which are calculated rather than sized by rule of thumb.
Local context
Why Carbis Bay is its own job.
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. That sets the scene before any design work begins. For structural calculations 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. It's the kind of detail that decides whether a Carbis Bay application gets approved at eight weeks or stalls in committee. The 1960s estate housing that dominate Carbis Bay (and continue out toward St Ives) set the tone for any structural calculations scheme here. 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
Structural work does not usually need planning permission in itself, but a beam depth can change a ceiling line, and a changed ceiling line can change an approved elevation.

Building stock
Across Carbis Bay (TR26) we work on Edwardian and 1930s detached villas, post-war bungalows, 1960s estate housing, modern coastal architect-designed homes. Each stock type drives a different structural calculations response — 1960s estate housing in particular needs careful detailing here.
Parish & policy
Carbis Bay sits in the parish of St Ives, which matters for how parish-level consultation lands on a structural calculations application.
Coverage
We cover TR26 from our studio, with regular structural calculations jobs also running in St Ives. Most Carbis Bay site visits get booked within the same week.
How quickly can you visit a Carbis Bay site?
Usually within the same week. Carbis Bay (TR26) is on our regular West Cornwall run, alongside St Ives. First visits are free and you'll get an honest feasibility view inside seven days.

FAQs
Carbis Bay Structural Calculations — local questions answered.
- We live in the house. Can a structural calculations 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.
- Who carries out the calculations?
- They are produced by a qualified structural engineer, and we coordinate the information, the drawings and the submission so you are not managing two separate appointments. In Carbis Bay specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- Do I need structural calculations to remove a wall?
- If the wall carries load, yes. Building control will ask for calculations before signing the work off, and a solicitor will ask for that sign off when the house is sold.
- Will a steel beam always be needed?
- Not always. Engineered timber can work well on shorter spans and is easier to install in a tight Cornish cottage, so the material choice follows the span, the loading and how the beam gets into the building.
- Are calculations included in a building regulation package?
- They are coordinated with it. We arrange the structural work and bring the results onto the drawings so building control receives one consistent set rather than two documents that disagree.
- How long do calculations take?
- For a straightforward beam over a removed wall it is usually a short turnaround once the survey information is in. Foundations, unusual spans and heavily loaded stone walls take longer because the checks are more involved.

If you only need documentation for a TR26 address, that is exactly where this service stops, and the fee reflects it. Parish-level consultation in St Ives is worth planning for, not reacting to.
