Architectural Design that reads Trethurgy 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 Trethurgy on the ground is half of the architectural design job — Trethurgy is a small rural hamlet in the PL26 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward small infill homes and farmhouses.
Trethurgy sits in Mid Cornwall — just off the A390; covering PL26 from St Austell, Bugle, St Dennis outward.

Trethurgy Architectural Design — local questions answered.
- 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. In Trethurgy specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- We live in the house. Can a architectural design in Trethurgy 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 Trethurgy 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 Trethurgy architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL26 address, not a build contract. For most Trethurgy householders that means a measured survey, an honest feasibility view, then the drawings the council and your builder both need.

- A written planning route for the PL26 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
Local context
Why Trethurgy is its own job.
Around Trethurgy (PL26), the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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 Trethurgy properly up front saves more time than any drawing tool ever will. Most of our architectural design work in Trethurgy lands on small infill homes, 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 Trethurgy.
01
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
02
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
03
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.
04
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
Our process
How a Trethurgy 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.
