Architectural Design that reads Tregrehan properly
We prepare site-specific concept design, planning drawings and supporting documents that give your project the strongest possible chance of consent — and a clear path through Cornwall Council's planning process. Reading Tregrehan on the ground is half of the architectural design job — Tregrehan is an estate-influenced village in the PL24 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward small infill plots and farm buildings.
Tregrehan sits in Mid Cornwall — just off the A390; covering PL24 from St Austell, Bugle, St Dennis outward.

Who this is for
In Tregrehan the architectural design brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Local watch-list
Local snags worth knowing before drawing a Tregrehan architectural design.
Watch #1
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Tregrehan
Watch #2
Party Wall notices and shallow roof voids typical of estate cottages in the PL24 district
Watch #3
Trussed roofs and shallow foundations in the later PL24 estates, which change the structural strategy
Local proof — Our Mid Cornwall workload means a Tregrehan architectural design project never has to wait for an out-of-county team to drive down.

Tregrehan Architectural Design — local questions answered.
- What happens if planning is refused?
- We review the officer's reasons, advise honestly on the strength of an appeal, and where a redesign is the better route, prepare a revised scheme. The free re-submission window inside twelve months can be used strategically. In Tregrehan specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- Will you visit the site before designing?
- Always. Cornish sites have wind, light, slope and access quirks that don't show up on a Google Street View. A site visit is built into every fee proposal.
- Do I need planning permission or is it permitted development?
- It depends on the property, the size and position of the works, and whether you are in a Conservation Area, AONB or Article 4 area. We'll review your address against the General Permitted Development Order at first consultation and tell you straight.
- We live in the house. Can a architectural design in Tregrehan 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 Tregrehan are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- Can you handle a Certificate of Lawfulness instead?
- Yes — for permitted development work it's worth the small extra step. You get a formal council certificate confirming your build is lawful, which protects you on resale and is often required by mortgage lenders.
- Do you produce building regulations drawings as well?
- Yes. Once planning is approved we prepare the full building regs package — sections, construction details, structural coordination and specification — drawn at 1:50 and 1:10 so the builder and building control have everything they need.

What you actually get on a Tregrehan architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL24 address, not a build contract. For most Tregrehan 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 PL24 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

Other work we do around Tregrehan
Tregrehan is covered from our St Austell 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.

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.
Scope
The parts of the job we can take on in Tregrehan
Not every project needs every stage. On a Tregrehan job we scope to what the site and the consent route actually require.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Local context
Why Tregrehan is its own job.
Around Tregrehan (PL24), landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. For architectural design 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. Reading Tregrehan properly up front saves more time than any drawing tool ever will. Most of our architectural design work in Tregrehan lands on small infill plots, with detailing that has to nod to the wider Bugle streetscape.
Planning note
Whether your project is permitted development, a householder application or full planning, the route through Cornwall Council shapes the drawings we prepare from day one.
What we focus on
Architectural Design considerations specific to Tregrehan.
01
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.
02
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
03
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
04
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
Our process
How a Tregrehan architectural design project runs.
Step 1
Brief and site visit
We meet on site, walk the plot and listen to how you want to live in the finished space.
Step 2
Feasibility and sketch options
Two or three design directions tested against budget, planning policy and site constraints.
Step 3
Concept refinement
We develop the chosen direction into a coordinated set of plans, elevations and sections.
Step 4
Planning submission
We submit the application, monitor it through validation and respond to any officer queries.
Step 5
Decision and next stage
On approval we move into building regulations and tender drawings.
Most architectural-only commissions run from a few weeks for small householder applications to several months for new builds and listed work.
Local fabric
What sets a Tregrehan architectural design brief apart.
Building stock
Across Tregrehan (PL24) we work on estate cottages, farm buildings, detached homes, converted outbuildings, small infill plots. Each stock type drives a different architectural design response — small infill plots in particular needs careful detailing here.
Parish & policy
Tregrehan sits in the parish of Tregrehan, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover PL24 from our studio, with regular architectural design jobs also running in St Austell, Bugle, St Dennis. Most Tregrehan site visits get booked within the same week.
Do you work in Tregrehan regularly?
Yes — Tregrehan and the wider PL24 catchment are core territory. We're typically on a Mid Cornwall site at least once a week, so logistics are baked in, not bolted on.
