Measured surveys in Port Isaac, the drawing everything else is built on
Every application, every quote and every construction detail depends on the existing drawings being right. In Port Isaac 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. A PL29 site visit comes before a Port Isaac sketch, every time — Port Isaac is a tight working fishing village on the rugged north coast, internationally recognised through TV (Doc Martin), with one of the densest Conservation Areas in Cornwall and severe access constraints, with a building stock that leans toward modern carefully detailed coastal homes and Victorian villas above the village.
Port Isaac sits in North Cornwall — just off the A39; covering PL29 from Trelights, Polzeath outward.

Local watch-list
The PL29 constraints that shape a measured survey brief.
Watch #1
Conservation Area controls on materials, window proportions and roof form through central Port Isaac
Watch #2
AONB landscape-impact testing on anything read in long views across North Cornwall
Watch #3
Exposure detailing on fishermen's cottages on Squeezy Belly Alley and around the harbour — fixings, render systems and joinery specified for salt-laden air
Watch #4
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Port Isaac
Who this is for
In Port Isaac 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.
Page purpose
What you actually get on a Port Isaac measured survey drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL29 address, not a build contract. For most Port Isaac 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 PL29 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
Where our work starts and stops on a PL29 project
These stages can be bought separately. Most PL29 projects use three of them.
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.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
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.
Who this is for
Our footing in North Cornwall
- 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 a measured survey enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Port Isaac 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.

Local context
Why Port Isaac is its own job.
Conservation Area covers the entire historic harbour; AONB and Heritage Coast across the parish. Access for construction is famously difficult — narrow lanes, steep grades, no on-street parking. That sets the scene before any design work begins. For measured survey specifically, parts of Port Isaac 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 Port Isaac 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. It's the kind of detail that decides whether a Port Isaac application gets approved at eight weeks or stalls in committee. The modern carefully detailed coastal homes that dominate Port Isaac (and continue out toward Tintagel) set the tone for any measured survey scheme here. 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. 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.
What we focus on
Measured Surveys considerations specific to Port Isaac.
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
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
Where a neighbouring property is attached, a party wall line has to be recorded accurately before any structural design begins.
04
Boundary positions, drainage runs and manhole covers matter as much as the house itself once an extension is proposed.

Our process
How a Port Isaac 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
Port Isaac 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 Port Isaac?
- 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 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. In Port Isaac specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- We live in the house. Can a measured survey in Port Isaac 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 Port Isaac are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
Local proof — Our North Cornwall workload means a Port Isaac measured survey project never has to wait for an out-of-county team to drive down.

If you take one thing from this page: in Port Isaac 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.
