One studio for architectural design in Charlestown
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 Charlestown starts with a measured walk-round — Charlestown is a Georgian-planned harbour village south of St Austell, World Heritage designated for its china clay shipping history, with tall ships still moored in the harbour, with a building stock that leans toward Georgian harbour cottages and Edwardian houses.
Charlestown sits in South Cornwall — covering PL25 from St Austell outward.

Our process
How a Charlestown 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 Charlestown homeowners come to us after a architectural design quote elsewhere felt vague on planning — we lead with feasibility instead.

Architectural Design considerations specific to Charlestown.
01
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
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 Charlestown is its own job.
Two things shape a Charlestown application: parish character and policy. On policy — conservation Area covers the entire historic harbour; World Heritage Site status applies. The Charlestown Estate operates a strong design code on materials and layout. For architectural design specifically, parts of Charlestown sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Charlestown drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Get that local reading right and the rest of the Charlestown programme tends to run on time. On Georgian harbour cottages in particular — the kind you'll also find toward St Austell — 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.

Charlestown is part of St Austell
Charlestown sits inside the St Austell catchment — we cover both as one architectural design territory.

What sets a Charlestown architectural design brief apart.
Building stock
Across Charlestown (PL25) we work on Georgian harbour cottages, Victorian villas, Edwardian houses, modern carefully matched coastal homes, converted clay-shipping warehouses. Each stock type drives a different architectural design response — Georgian harbour cottages in particular needs careful detailing here.
Parish & policy
Charlestown sits in the parish of St Austell, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover PL25 from our studio, with regular architectural design jobs also running in St Austell. Most Charlestown site visits get booked within the same week.
Can you handle both planning and build in Charlestown?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Charlestown builder we can stop at a tender-ready Full Plans pack instead.

FAQs
Charlestown Architectural Design — local questions answered.
- 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. In Charlestown specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- 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.
- 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.
