Architectural Design & Planning in Mawnan
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. A Mawnan brief starts on the street, not the screen — Mawnan is a rural parish in the TR11 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward rural cottages and scattered modern homes.
Mawnan sits in South Cornwall — just off the A39; covering TR11 from Mawnan Smith, Durgan, Truro outward.

Who this is for
In Mawnan the architectural design brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.

Mawnan 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 specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- We live in the house. Can a architectural design in Mawnan 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 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.
- 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.
- 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.

The parts of the job we can take on in Mawnan
These stages can be bought separately. Most TR11 projects use three of them.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
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.
Who this is for
What we can genuinely back up in Mawnan
- Design and build are offered from the same studio, which means the person answering your Mawnan questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a architectural design enquiry does not get passed between firms.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
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.

Mawnan is covered from our Mawnan Smith 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.
Page purpose
What you actually get on a Mawnan 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 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
Local context
Why Mawnan is its own job.
Open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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; 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. So every Mawnan job runs as a TR11-specific piece of work — local policy, local fabric, local builders. Most of our architectural design work in Mawnan lands on rural cottages, with detailing that has to nod to the wider Durgan 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 Mawnan.
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
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.
Our process
How a Mawnan 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
Mawnan architectural design — the local-studio difference.

Across Mawnan (TR11) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different architectural design response — rural cottages in particular needs careful detailing here.
Parish & policy
Mawnan sits in the parish of Mawnan, which matters for how parish-level consultation lands on a architectural design application.
