Tresillian 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. Anchor any Tresillian architectural design in the local fabric and the rest follows — Tresillian is a village east of Truro at the head of the Tresillian River, AONB-designated, with a Conservation Area covering the village core, with a building stock that leans toward post-war bungalows and traditional cob and granite cottages.
Tresillian sits in Mid Cornwall — covering TR2 from Truro, Tregony, Ladock outward.

Who this is for
Tresillian runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every architectural design enquiry from the use-class up.

Tresillian Architectural Design — local questions answered.
- How long does a planning application take in Tresillian?
- 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 Tresillian specifically, we'd start by checking the Conservation Area boundary 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.
- 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.
- 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.
Local context
Why Tresillian is its own job.
The planning backdrop in Mid Cornwall is real, not abstract: conservation Area covers the village; AONB across the parish. Riverside ecology and views shape applications on the southern edge. For architectural design specifically, parts of Tresillian sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Tresillian drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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 TR2 parish brief as the design brief and the Tresillian application has somewhere to land. Whether the project is on post-war bungalows 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.
What we focus on
Architectural Design considerations specific to Tresillian.
01
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
02
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
03
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.
04
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
Our process
How a Tresillian 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
Choosing a architectural design team that actually knows TR2.
Building stock
Across Tresillian (TR2) we work on traditional cob and granite cottages, Victorian villas, Edwardian houses, post-war bungalows, modern AONB-sensitive infill. Each stock type drives a different architectural design response — post-war bungalows in particular needs careful detailing here.
Parish & policy
Tresillian sits in the parish of St Erme, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover TR2 from our studio, with regular architectural design jobs also running in Truro, Tregony, Ladock. Most Tresillian site visits get booked within the same week.
What does a first Tresillian consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR2 plot and follow up with a written feasibility note inside a week — no obligation either way.

Tresillian sits inside the Truro catchment — we cover both as one architectural design territory.
