Architectural Design for Mullion (TR12)
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 Mullion starts with a measured walk-round — Mullion is the largest village on the Lizard Peninsula, AONB-designated, with a fifteenth-century church, a working cove and the highest concentration of period housing on the peninsula, with a building stock that leans toward modern AONB-sensitive replacement dwellings and Edwardian guesthouses.
Mullion sits in Lizard Peninsula — covering TR12 from The Lizard outward.

Our process
How a Mullion 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 — We typically have one or two architectural design jobs live in the TR12 area at any time, so the local planning officers know our drawings on sight.

Architectural Design considerations specific to Mullion.
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 Mullion is its own job.
In Mullion the planning picture is specific: mullion Conservation Area covers the village centre; the wider parish is entirely within the AONB and includes Heritage Coast designation. Cliff-edge and coastal margin sites face the strictest controls in West Cornwall. For architectural design specifically, parts of Mullion 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 Mullion 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 Mullion (TR12) project different from a generic Cornwall scheme — and is the whole reason we work this way. On modern AONB-sensitive replacement dwellings in particular — the kind you'll also find toward Helston — 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.

Mullion architectural design — the local-studio difference.
Building stock
Across Mullion (TR12) we work on granite cottages around the church, Edwardian guesthouses, 1960s coastal bungalows, modern AONB-sensitive replacement dwellings. Each stock type drives a different architectural design response — modern AONB-sensitive replacement dwellings in particular needs careful detailing here.
Parish & policy
Mullion is its own town in Lizard Peninsula, with planning history that's specific to the TR12 catchment.
Coverage
We cover TR12 from our studio, with regular architectural design jobs also running in The Lizard, Helston. Most Mullion site visits get booked within the same week.
Can you handle both planning and build in Mullion?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Mullion builder we can stop at a tender-ready Full Plans pack instead.

FAQs
Mullion 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 Mullion 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.
