Measured building surveys in Mullion — accurate TR12 drawings
A measured survey in Mullion is the foundation every design decision rests on — done badly, every downstream drawing carries its errors. We scan with 3D laser (typically ±3mm accuracy) and deliver AutoCAD-ready plans, sections and elevations. On granite cottages around the church, hand-measure alone misses the twists and out-of-plumb walls that always exist. 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 — just off the A394; covering TR12 from Mawgan, Ruan Minor, The Lizard outward.

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 Ruan Minor — the architectural design brief always has to read the existing fabric first. Where a property sits inside a conservation area or is listed, the assessment tends to turn on materials, window detailing and how visible the change is from the street rather than floor area alone. Cornwall Council's conservation team, or the Planning Portal, is the right place to confirm what applies to a specific address. Salt air and prevailing wind change specification long before they change planning. We tend to draw weathering details in full, then check whether coastal or AONB policy narrows the design options for this address.
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 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.

Page purpose
What you actually get on a Mullion architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR12 address, not a build contract. For most Mullion 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 TR12 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
Scope options for Mullion clients
Not every project needs every stage. On a Mullion 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.
Who this is for
Straight facts about working with us here
- Applications for Mullion 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 an 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.
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.

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 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.

Mullion Architectural Design — local questions answered.
- How much does a measured building survey cost in Mullion?
- £450–£850 for a typical 3-bed house in Mullion (TR12), including plans, sections and elevations. Larger properties and listed buildings quoted per site visit.
- How long does the survey take?
- Half a day on site for a standard house; drawings issued within 5–7 working days. Larger commercial jobs quoted separately.
- Do I need a measured survey for planning?
- Yes — Cornwall Council requires accurate existing plans/elevations for any householder application. A rough sketch will fail validation.
- 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.
- We live in the house. Can an architectural design in Mullion 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 Mullion 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.

A proper Mullion measured survey costs a fraction of the design fees it protects — and a rounding error at survey stage compounds into a build-cost variation later.
