Treliske architectural design — a Mid Cornwall studio
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. In Treliske, that work is shaped by the place itself — Treliske is a town-edge neighbourhood in the TR1 area, where modern housing, larger gardens and edge-of-settlement plots create practical development opportunities, with a building stock that leans toward detached houses and infill plots.
Treliske sits in Mid Cornwall — just off the A390; covering TR1 from Truro, St Michael Penkivel, Calenick outward.

Page purpose
What you actually get on a Treliske architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR1 address, not a build contract. For most Treliske 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 TR1 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 Treliske
Not every project needs every stage. On a Treliske job we scope to what the site and the consent route actually require.
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.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Local watch-list
What usually catches architectural design projects out in Treliske.
Watch #1
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Treliske
Watch #2
Trussed roofs and shallow foundations in the later TR1 estates, which change the structural strategy
Who this is for
Why this page exists, and who it is for
- Applications for Treliske are handled through Cornwall Council, with St Austell the nearest planning office we deal with regularly.
- Design and build are offered from the same studio, which means the person answering your Treliske questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a architectural design 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
Architectural Design considerations specific to Treliske.
01
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
02
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
03
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
04
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.

Local context
Why Treliske is its own job.
The planning backdrop in Mid Cornwall is real, not abstract: neighbour amenity, highways, drainage and the transition from built-up edge to countryside are usually the planning pressure points. 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. Treat the TR1 parish brief as the design brief and the Treliske application has somewhere to land. Whether the project is on detached houses in the centre or further out toward Truro, the architectural design response is locally tuned.
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.
Our process
How a Treliske 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.
FAQs
Treliske Architectural Design — local questions answered.
- How long does a planning application take in Treliske?
- Householder applications are decided in eight weeks from validation in most cases; full planning runs to thirteen weeks. Validation itself can take one to three weeks at Cornwall Council depending on workload, so plan for around three to four months from drawing start to decision. In Treliske specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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 Treliske 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 Treliske are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
Treliske is part of Truro
Treliske sits inside the Truro catchment — we cover both as one architectural design territory.

Follow the chain: survey, drawings, build
Treliske is covered from our Truro 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.
