Architectural Design & Planning in Treen
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 Treen on the ground is half of the architectural design job — Treen is a coastal village in the TR19 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward holiday homes and replacement dwellings.
Treen sits in Penwith — covering TR19 from St Buryan, Truro, St Austell outward.

Who this is for
Treen 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.
Local context
Why Treen is its own job.
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; coastal salt-laden air around Treen drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. So every Treen job runs as a TR19-specific piece of work — local policy, local fabric, local builders. Most of our architectural design work in Treen lands on holiday homes, with detailing that has to nod to the wider Truro 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 Treen.
01
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.
02
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
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.
Our process
How a Treen 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
Treen 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 Treen 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 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.
- 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.
Treen is part of St Buryan
Treen sits inside the St Buryan catchment — we cover both as one architectural design territory.
