Measured surveys in Marazion, the drawing everything else is built on
Every application, every quote and every construction detail depends on the existing drawings being right. In Marazion 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. Anchor any Marazion measured survey in the local fabric and the rest follows — Marazion sits opposite St Michael's Mount across a tidal causeway and is one of Cornwall's oldest chartered towns, designated AONB for its setting, with a building stock that leans toward Victorian villas and granite cottages.
Marazion sits in West Cornwall — just off the A30; with Truro the closest city; 3 miles from Penzance.

Page purpose
What you actually get on a Marazion measured survey drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR17 address, not a build contract. For most Marazion 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 TR17 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
What we can draw, survey and build around Marazion
These stages can be bought separately. Most TR17 projects use three of them.
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.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.

Who this is for
Why this page exists, and who it is for
- 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.
- Sites we know on the ground here include the area around the causeway and St Michael's Mount.
- Design and build are offered from the same studio, which means the person answering your Marazion questions has seen the detail built.
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.
What we focus on
Measured Surveys considerations specific to Marazion.
01
Floor levels in older cottages frequently step between rooms, which changes the whole approach to a level access threshold or a new opening.
02
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.
03
Boundary positions, drainage runs and manhole covers matter as much as the house itself once an extension is proposed.
04
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.

Local context
Why Marazion is its own job.
The planning backdrop in West Cornwall is real, not abstract: the whole town centre is within the Conservation Area and the AONB; views to and from St Michael's Mount are a material planning consideration on most schemes. Roof pitches, ridge heights and seaward elevations are tightly controlled. For measured survey specifically, parts of Marazion 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 Marazion drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Treat the TR17 parish brief as the design brief and the Marazion application has somewhere to land. Whether the project is on Victorian villas in the centre or further out toward Goldsithney, the measured survey response is locally tuned. 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. 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
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.

How a Marazion 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.
FAQs
Marazion 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 Marazion?
- 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.
- We live in the house. Can a measured survey in Marazion 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 Marazion are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- What is a measured survey and why do I need one?
- It is an accurate dimensional record of your existing building, drawn to scale. You need one because planning and building control both require existing and proposed drawings, and because a builder pricing from guessed dimensions will price in a risk margin you end up paying for. In Marazion specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- How long does the survey take?
- Most domestic properties are measured in half a day to a day on site, with drawn output following shortly afterwards. We tell you the drawing turnaround when we book the visit rather than leaving it open ended.

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