Architectural Design for Trewennack (TR13)
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 Trewennack means starting from the TR13 context — Trewennack is a small rural hamlet in the TR13 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward bungalows and cottages.
Trewennack sits in West Cornwall — just off the A30; covering TR13 from Helston, Breage, Ashton outward.

Why Trewennack is its own job.
In Trewennack the planning picture is specific: the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. That local reading is what makes a Trewennack (TR13) project different from a generic Cornwall scheme — and is the whole reason we work this way. On bungalows in particular — the kind you'll also find toward Sithney — 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 Trewennack.
01
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
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
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.

What you actually get on a Trewennack architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR13 address, not a build contract. For most Trewennack 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 TR13 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

Feasibility and sketch options
Two or three design directions tested against budget, planning policy and site constraints.

We develop the chosen direction into a coordinated set of plans, elevations and sections.

Trewennack 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 Trewennack specifically, we'd start by checking the latest parish-level planning history 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.
- We live in the house. Can a architectural design in Trewennack 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 Trewennack are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
