Measured surveys in St Austell, the drawing everything else is built on
Every application, every quote and every construction detail depends on the existing drawings being right. In St Austell that matters more than in a modern estate, because older stone and cob fabric moves, floors step between rooms and wall thicknesses change between storeys. A survey records the building as it is, which is the only sound basis for designing anything. A measured survey records the building as it stands, not as the original drawings claimed it would be. Every planning drawing, building regulation package and builder's quote we produce sits on one, because a wall that is 60mm out of square on paper becomes a 60mm problem on site. Working in St Austell means starting from the PL25 context — St Austell is the principal town of mid-Cornwall, historically the centre of the china clay industry and now a substantial market town with the Eden Project on its doorstep, with a building stock that leans toward Victorian terraces in the clay villages and post-war estates.
St Austell sits in Mid Cornwall — just off the A390; with Truro the closest city; covering PL25 from Mevagissey, Carlyon Bay outward.

St Austell Measured Surveys — local questions answered.
- What is a measured survey?
- An accurate dimensional record of an existing building, drawn to scale as plans, elevations and sections. It captures wall thicknesses, floor levels, openings and the site around the building.
- How much does a measured survey cost in St Austell?
- It depends on the size of the property, the number of storeys and how irregular the fabric is. We quote a fixed figure once we know the address and rough floor area, and where the survey runs into a full design commission it is usually folded into the package.
- Can I use the survey elsewhere?
- Yes. You receive scaled PDFs and CAD files, and they are yours whether or not we go on to do the design work.
- What do you need access to?
- Every room, plus the loft, any cellar and any outbuilding involved in the proposal. Anything not accessible has to be recorded on the drawing as an assumption, and assumptions are what cause variations later.
- Do you survey land and levels as well as buildings?
- We record site levels and boundary positions to the level a householder application and a building regulation package need. Where a scheme needs a full topographical survey to a fixed datum, we will say so and coordinate it. In St Austell specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- How much does a measured survey cost?
- It depends on floor area, the number of storeys and how irregular the building is. A standard three bedroom house is a straightforward half day on site; a rambling farmhouse with outbuildings takes considerably longer. We quote a fixed figure once we know the address and rough size, and where the survey leads into a full design commission it is usually folded into the package fee.
- Do you need access to every room?
- Yes, including lofts, cellars and any outbuilding that touches the proposal. Anything we cannot access has to be noted as an assumption on the drawing, and assumptions are what cause variations later.

Where to go next from St Austell
St Austell works as a hub for us: the same measured survey team covers Charlestown and the surrounding PL25 villages, so a site visit here often takes in more than one address.
Page purpose
What you actually get on a St Austell measured survey drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL25 address, not a build contract. For most St Austell 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 PL25 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 St Austell clients
Not every project needs every stage. On a St Austell job we scope to what the site and the consent route actually require.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Commercial drawings
Change of use, fit-out and access documentation for Class E and mixed-use premises.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Who this is for
Straight facts about working with us here
- Commercial and mixed-use work in St Austell tends to sit around Holmbush retail park.
- Design and build are offered from the same studio, which means the person answering your St Austell questions has seen the detail built.
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Sites we know on the ground here include the area around Holy Trinity Church and White River shopping centre.
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 St Austell is its own job.
Two things shape a St Austell application: parish character and policy. On policy — conservation Area covers the historic centre. The china clay legacy shapes the surrounding landscape and creates substantial brownfield redevelopment opportunities. For measured survey specifically, parts of St Austell sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. Get that local reading right and the rest of the St Austell programme tends to run on time. On Victorian terraces in the clay villages in particular — the kind you'll also find toward Charlestown — the measured survey brief always has to read the existing fabric first. Historic fabric changes the sequence: survey first, then design around what the building can take. Consent routes for listed buildings sit separately from ordinary planning, so treat any general guidance here as a starting point and check with Cornwall Council. Coastal sites tend to raise questions about roof form, glazing exposure and how a scheme reads from public viewpoints. Those are policy judgements rather than fixed rules, so the local planning authority or the Planning Portal should confirm the position for a given plot.
Planning note
Cornwall Council will not validate an application without accurate existing plans and elevations, so the survey is the first thing that gets done, not an optional extra.

Measured Surveys considerations specific to St Austell.
01
Roof pitches on slate roofs vary along the length of the run, and a survey that misses that produces a dormer or rooflight detail that will not sit flush.
02
Where a neighbouring property is attached, a party wall line has to be recorded accurately before any structural design begins.
03
Floor levels in older cottages frequently step between rooms, which changes the whole approach to a level access threshold or a new opening.
04
Boundary positions, drainage runs and manhole covers matter as much as the house itself once an extension is proposed.
Our process
How a St Austell measured survey project runs.
Step 1
Address and scope
You send the address and rough size, we confirm a fixed fee and a date.
Step 2
Site visit
Room by room measurement, elevations, levels, photographs and drainage.
Step 3
Drawing up
The measurements are drawn as existing plans, elevations and sections at scale.
Step 4
Issue and check
You receive PDF and CAD files, and we walk through anything unusual we found.
Step 5
Design or handover
The survey becomes the base drawing for design, or it is yours to take elsewhere.
Surveys range from a single room reconfiguration to a full farmstead with several outbuildings recorded in one visit.
Local fabric
St Austell measured surveys — the local-studio difference.
Building stock
Across St Austell (PL25) we work on Georgian townhouses, Victorian terraces in the clay villages, Edwardian villas, post-war estates, modern Persimmon and Wainhomes estates. Each stock type drives a different measured survey response — Victorian terraces in the clay villages in particular needs careful detailing here.
Parish & policy
St Austell is its own town in Mid Cornwall, with planning history that's specific to the PL25 catchment.
Coverage
We cover PL25 from our studio, with regular measured survey jobs also running in Charlestown. Most St Austell site visits get booked within the same week.
Can you handle both planning and build in St Austell?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing St Austell builder we can stop at a tender-ready Full Plans pack instead.

If you take one thing from this page: in St Austell do not let anyone design from an old estate agent floor plan. It is the cheapest possible saving and the most expensive one to unpick on site.
