Structural Calculations for Crafthole (PL11)
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. Crafthole sits in East Cornwall, and that geography ends up in the drawings — Crafthole is a commuter village in the PL11 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward modern estates and garden infill plots.
Crafthole sits in East Cornwall — just off the A38; covering PL11 from Torpoint, Millbrook, Antony outward.

Why Crafthole is its own job.
In Crafthole the planning picture is specific: applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. For structural calculations specifically, 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 local reading is what makes a Crafthole (PL11) project different from a generic Cornwall scheme — and is the whole reason we work this way. On modern estates in particular — the kind you'll also find toward St John — the structural calculations brief always has to read the existing fabric first. Historic fabric changes the sequence: survey first, then design around what the building can take. Consent routes for listed buildings sit separately from ordinary planning, so treat any general guidance here as a starting point and check with Cornwall Council. Granite and cob walls do not behave like modern cavity construction. Breathability, damp movement and structural openings all need drawing properly, and building control will want that shown rather than assumed.
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.
What we focus on
Structural Calculations considerations specific to Crafthole.
01
Cornish rubble stone walls behave differently to brick or block, and load paths through them have to be considered rather than assumed.
02
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.
03
Where a party wall is affected, structural information is also what the neighbour's surveyor will ask to see.
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.

Where to go next from Crafthole
Crafthole is covered from our Torpoint run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
What you actually get on a Crafthole structural calculations drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL11 address, not a build contract. For most Crafthole 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 PL11 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
Scope options for Crafthole clients
These stages can be bought separately. Most PL11 projects use three of them.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Who this is for
Straight facts about working with us here
- Drawings, planning and building regulations are all produced in-house, so a structural calculations enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Crafthole questions has seen the detail built.
- Applications for Crafthole are handled through Cornwall Council, with Liskeard 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.
Our process
How a Crafthole 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 fabric
One PL11 studio, one structural calculations job — start to finish.
Building stock
Across Crafthole (PL11) we work on post-war semis, bungalows, modern estates, older cottages, garden infill plots. Each stock type drives a different structural calculations response — modern estates in particular needs careful detailing here.
Parish & policy
Crafthole sits in the parish of Crafthole, which matters for how parish-level consultation lands on a structural calculations application.
Coverage
We cover PL11 from our studio, with regular structural calculations jobs also running in Torpoint, Millbrook. Most Crafthole site visits get booked within the same week.
Can you handle both planning and build in Crafthole?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Crafthole builder we can stop at a tender-ready Full Plans pack instead.

Crafthole Structural Calculations — local questions answered.
- 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. In Crafthole specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- We live in the house. Can a structural calculations in Crafthole 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 Crafthole are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
- 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.
Crafthole is part of Torpoint
Crafthole sits inside the Torpoint catchment — we cover both as one structural calculations territory.

The point of a Crafthole structural calculations package is certainty on paper before money goes into the ground. Parish-level consultation in Crafthole is worth planning for, not reacting to.
