Architectural Design for Mawnan Smith (TR11)
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. Mawnan Smith sits in South Cornwall, and that geography ends up in the drawings — Mawnan Smith is an AONB village south of Falmouth between the Helford River and Maenporth Beach, with a strong period property market and a tight Conservation Area at its centre, with a building stock that leans toward high-end modern architect builds and Edwardian houses.
Mawnan Smith sits in South Cornwall — just off the A39; with Truro the closest city; 3 miles from Falmouth.

Mawnan Smith 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 Mawnan Smith specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- We live in the house. Can a architectural design in Mawnan Smith 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 Mawnan Smith 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.

Mawnan Smith works as a hub for us: the same architectural design team covers Mawnan, Durgan and the surrounding TR11 villages, so a site visit here often takes in more than one address.
Page purpose
What you actually get on a Mawnan Smith architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR11 address, not a build contract. For most Mawnan Smith 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 TR11 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
Scope

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.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Who this is for
Straight facts about working with us here
- Applications for Mawnan Smith 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.
- Sites we know on the ground here include the area around the village green and Trebah Garden.
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.
Local context
Why Mawnan Smith is its own job.
In Mawnan Smith the planning picture is specific: conservation Area covers the village core; AONB across the parish. Helford River views and ecology constraints shape applications on the southern edge. For architectural design specifically, parts of Mawnan Smith sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Mawnan Smith drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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 Mawnan Smith (TR11) project different from a generic Cornwall scheme — and is the whole reason we work this way. On high-end modern architect builds in particular — the kind you'll also find toward Maenporth — 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.

Architectural Design considerations specific to Mawnan Smith.
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.
Our process
How a Mawnan Smith 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 fabric
One TR11 studio, one architectural design job — start to finish.
