Treverva architectural design — a South 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. On a Treverva site, the brief always meets the place — Treverva is a rural parish in the TR10 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward converted barns and rural cottages.
Treverva sits in South Cornwall — covering TR10 from Falmouth, Flushing, Budock Water outward.

Who this is for
Treverva 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.

Tighter Local Plan tests on isolated rural dwellings
Local proof — Recent architectural design enquiries from Treverva have clustered around converted barns — we know the route through Cornwall Council on these.

Treverva Architectural Design — local questions answered.
- 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. In Treverva specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- How long does a planning application take in Cornwall?
- 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.
- 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 Treverva is its own job.
The planning backdrop in South Cornwall is real, not abstract: open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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 TR10 parish brief as the design brief and the Treverva application has somewhere to land. Whether the project is on converted barns in the centre or further out toward Falmouth, 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 Treverva.
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 Treverva 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
Why a South Cornwall studio is the right fit for Treverva architectural design.
Building stock
Across Treverva (TR10) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different architectural design response — converted barns in particular needs careful detailing here.
Parish & policy
Treverva sits in the parish of Treverva, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover TR10 from our studio, with regular architectural design jobs also running in Falmouth, Flushing, Budock Water. Most Treverva site visits get booked within the same week.
What does a first Treverva consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR10 plot and follow up with a written feasibility note inside a week — no obligation either way.

Treverva sits inside the Falmouth catchment — we cover both as one architectural design territory.
