Measured surveys in Truro, the drawing everything else is built on
Every application, every quote and every construction detail depends on the existing drawings being right. In Truro 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. Reading Truro on the ground is half of the measured survey job — Truro is Cornwall's only city, the county town and home to Cornwall Council itself, with a Georgian core, three-spired cathedral and Lemon Quay at its centre, with a building stock that leans toward Edwardian villas and modern development at West Langarth.
Truro sits in Mid Cornwall — just off the A390; covering TR1 from Threemilestone, Shortlanesend, Kea outward.

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

Truro 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 Truro?
- 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.
- 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. In Truro specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- We live in the house. Can a measured survey in Truro 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 Truro are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Page purpose
What you actually get on a Truro measured survey drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR1 address, not a build contract. For most Truro 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 TR1 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 Truro is its own job.
The Truro Conservation Area covers a wide central zone including Lemon Street, the cathedral precinct and the river frontage. As the home of Cornwall Council planning, it tends to set the tone for design expectations across the county. For measured survey specifically, parts of Truro sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. So every Truro job runs as a TR1-specific piece of work — local policy, local fabric, local builders. Most of our measured survey work in Truro lands on Edwardian villas, with detailing that has to nod to the wider Threemilestone 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.
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 Truro.
01
Where a neighbouring property is attached, a party wall line has to be recorded accurately before any structural design begins.
02
Floor levels in older cottages frequently step between rooms, which changes the whole approach to a level access threshold or a new opening.
03
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.
04
Boundary positions, drainage runs and manhole covers matter as much as the house itself once an extension is proposed.
Our process
How a Truro 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 TR1 studio, one measured survey job — start to finish.
Building stock
Across Truro (TR1) we work on Georgian townhouses on Lemon Street, Victorian terraces in Hendra and Highertown, Edwardian villas, 1960s estates, modern development at West Langarth. Each stock type drives a different measured survey response — Edwardian villas in particular needs careful detailing here.
Parish & policy
Truro is its own city in Mid Cornwall, with planning history that's specific to the TR1 catchment.
Coverage
We cover TR1 from our studio, with regular measured survey jobs also running in Mid Cornwall. Most Truro site visits get booked within the same week.
Do you work in Truro regularly?
Yes — Truro and the wider TR1 catchment are core territory. We're typically on a Mid Cornwall site at least once a week, so logistics are baked in, not bolted on.

If you take one thing from this page: in Truro 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.
