Measured surveys in St Agnes, the drawing everything else is built on
Every application, every quote and every construction detail depends on the existing drawings being right. In St Agnes that matters more than in a modern estate, because walls have been rebuilt and rendered over generations and rarely measure what the deeds suggest. 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. The St Agnes version of this work has its own character — St Agnes is a former mining village on the north coast with a strong artistic community, AONB and World Heritage designation, and dramatic coastal mining ruins (Wheal Coates) on its doorstep, with a building stock that leans toward AONB-sensitive replacement dwellings and Victorian villas.
St Agnes sits in North Cornwall — just off the A39; covering TR5 from Mount Hawke, Mithian, Porthtowan outward.

Why St Agnes is its own job.
Around St Agnes (TR5), conservation Area covers Vicarage Road, Town Hill and the church area. AONB, Heritage Coast and World Heritage Site designations across the parish. Mining heritage shapes most planning conversations. For measured survey specifically, parts of St Agnes 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; coastal salt-laden air around St Agnes drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Reading St Agnes properly up front saves more time than any drawing tool ever will. Most of our measured survey work in St Agnes lands on AONB-sensitive replacement dwellings, with detailing that has to nod to the wider Porthtowan streetscape. On older stock, the practical constraint is usually joinery, render and roof line rather than the extension itself. We draw those details out early so a measured survey submission is not sent back for missing information. Confirm listing status with the local planning authority before assuming permitted development. Exposure is the real design driver near the water: wind-driven rain, salt and driving damp push detailing towards better weathering, sheltered openings and robust fixings. Where an AONB or coastal policy applies, visual impact usually carries more weight than size.
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.
What we focus on
Measured Surveys considerations specific to St Agnes.
01
Boundary positions, drainage runs and manhole covers matter as much as the house itself once an extension is proposed.
02
Cornish stone and cob walls are rarely parallel and often vary in thickness between floors, so wall build-ups have to be measured room by room rather than assumed.
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
Where a neighbouring property is attached, a party wall line has to be recorded accurately before any structural design begins.
Scope
The parts of the job we can take on in St Agnes
These stages can be bought separately. Most TR5 projects use three of them.
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.
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.
Who this is for
What we can genuinely back up in St Agnes
- Design and build are offered from the same studio, which means the person answering your St Agnes questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a measured survey 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.

St Agnes works as a hub for us: the same measured survey team covers Goonbell and the surrounding TR5 villages, so a site visit here often takes in more than one address.
Page purpose
What you actually get on a St Agnes measured survey drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR5 address, not a build contract. For most St Agnes 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 TR5 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
Our process
How a St Agnes 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
One TR5 studio, one measured survey job — start to finish.
Building stock
Across St Agnes (TR5) we work on miners' terraces, Victorian villas, Edwardian guesthouses, modern coastal architect builds, AONB-sensitive replacement dwellings. Each stock type drives a different measured survey response — AONB-sensitive replacement dwellings in particular needs careful detailing here.
Parish & policy
St Agnes is its own town in North Cornwall, with planning history that's specific to the TR5 catchment.
Coverage
We cover TR5 from our studio, with regular measured survey jobs also running in Perranporth. Most St Agnes site visits get booked within the same week.
Do you work in St Agnes regularly?
Yes — St Agnes and the wider TR5 catchment are core territory. We're typically on a North Cornwall site at least once a week, so logistics are baked in, not bolted on.

St Agnes 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 Agnes?
- 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 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. In St Agnes specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
