Architectural Design for Trevellas (TR5)
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. The way we approach architectural design in Trevellas starts with a measured walk-round — Trevellas is a coastal village in the TR5 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward granite cottages and holiday homes.
Trevellas sits in North Cornwall — covering TR5 from St Agnes, Mount Hawke, Mithian outward.

Our process
How a Trevellas 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 proof — Most Trevellas architectural design clients we work with are second-time builders — they've seen the templated approach fail once already.

Architectural Design considerations specific to Trevellas.
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
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
04
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
Local context
Why Trevellas is its own job.
In Trevellas the planning picture is specific: coastal setting and landscape sensitivity mean rooflines, glazing, drainage and external materials need careful handling from the first sketch. For architectural design specifically, 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; coastal salt-laden air around Trevellas drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a Trevellas (TR5) project different from a generic Cornwall scheme — and is the whole reason we work this way. On granite cottages in particular — the kind you'll also find toward Goonbell — the architectural design brief always has to read the existing fabric first.
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 sets a Trevellas architectural design brief apart.
Building stock
Across Trevellas (TR5) we work on granite cottages, rendered coastal houses, holiday homes, bungalows, replacement dwellings. Each stock type drives a different architectural design response — granite cottages in particular needs careful detailing here.
Parish & policy
Trevellas sits in the parish of Trevellas, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover TR5 from our studio, with regular architectural design jobs also running in St Agnes, Mount Hawke, Mithian. Most Trevellas site visits get booked within the same week.
Can you handle both planning and build in Trevellas?

FAQs
Trevellas 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 Trevellas specifically, we'd start by checking AONB landscape sensitivity 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.
- 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.
- 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.
