Architectural Design for Trewellard (TR19)
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. Working in Trewellard means starting from the TR19 context — Trewellard is a former mining settlement in the TR19 area, with granite terraces, chapel buildings and industrial landscape character still visible, with a building stock that leans toward miners cottages and chapel conversions.
Trewellard sits in Penwith — just off the A30; covering TR19 from Pendeen, Morvah, Lower Boscaswell outward.

Why Trewellard is its own job.
In Trewellard the planning picture is specific: mining heritage, old plot widths and traditional materials make proportion and detailing more important than generic extension templates. 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; 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. That local reading is what makes a Trewellard (TR19) project different from a generic Cornwall scheme — and is the whole reason we work this way. On miners cottages in particular — the kind you'll also find toward Truro — 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 we focus on
Architectural Design considerations specific to Trewellard.
01
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
02
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.
03
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
04
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
Who this is for
Straight facts about working with us here
- Applications for Trewellard are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a architectural design enquiry does not get passed between firms.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.
Scope
Scope options for Trewellard clients
Not every project needs every stage. On a Trewellard job we scope to what the site and the consent route actually require.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Page purpose
What you actually get on a Trewellard architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR19 address, not a build contract. For most Trewellard householders that means a measured survey, an honest feasibility view, then the drawings the council and your builder both need.
- Measured survey and existing drawings before any proposal is drawn
- A written planning route for the TR19 address, including whether permitted development is realistically available
- Proposed plans, elevations and site plan at the scales the authority expects
- Submission and validation handling, plus responses to officer queries

Where to go next from Trewellard
Trewellard is covered from our Pendeen run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Our process
How a Trewellard 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.

One TR19 studio, one architectural design job — start to finish.
Building stock
Across Trewellard (TR19) we work on miners cottages, granite terraces, chapel conversions, workers cottages, post-war estates. Each stock type drives a different architectural design response — miners cottages in particular needs careful detailing here.
Parish & policy
Trewellard sits in the parish of Trewellard, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover TR19 from our studio, with regular architectural design jobs also running in Pendeen, Morvah, Lower Boscaswell. Most Trewellard site visits get booked within the same week.
Can you handle both planning and build in Trewellard?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Trewellard builder we can stop at a tender-ready Full Plans pack instead.

Trewellard 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 Trewellard specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- We live in the house. Can a architectural design in Trewellard be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Trewellard are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
Trewellard is part of Pendeen
Trewellard sits inside the Pendeen catchment — we cover both as one architectural design territory.
