Measured building surveys in Pentewan — accurate PL26 drawings
A measured survey in Pentewan is the foundation every design decision rests on — done badly, every downstream drawing carries its errors. We scan with 3D laser (typically ±3mm accuracy) and deliver AutoCAD-ready plans, sections and elevations. On planned harbour cottages, hand-measure alone misses the twists and out-of-plumb walls that always exist. We prepare site-specific concept design, planning drawings and supporting documents that give your project the strongest possible chance of consent — and a clear path through Cornwall Council's planning process. On a Pentewan site, the brief always meets the place — Pentewan is an AONB former china clay shipping village south of St Austell, with a tight planned Conservation Area around the silted-up harbour and the holiday park inland, with a building stock that leans toward planned harbour cottages and modern AONB-sensitive infill.
Pentewan sits in South Cornwall — just off the B3273; with Truro the closest city; 0 miles from Pentewan, 5 miles from St Austell.

Page purpose
What you actually get on a Pentewan architectural design drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL26 address, not a build contract. For most Pentewan 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 PL26 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 Pentewan
Not every project needs every stage. On a Pentewan 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.
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.
Local watch-list
Common Pentewan pitfalls we plan around.

Who this is for
Why this page exists, and who it is for
- Sites we know on the ground here include the area around the inner harbour and Polkirt Hill.
- Drawings, planning and building regulations are all produced in-house, so an architectural design 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.
- Applications for Pentewan are handled through Cornwall Council, with Truro the nearest planning office we deal with regularly.
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
Architectural Design considerations specific to Pentewan.
01
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
02
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
03
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
04
Design and Access Statements are increasingly scrutinised — generic templates rarely cut it on sensitive Cornish sites.

Local context
Why Pentewan is its own job.
Locally, conservation Area covers the harbour village; AONB across the parish. Former harbour silting and Pentewan Sands holiday park shape most local planning conversations. For architectural design specifically, parts of Pentewan 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 Pentewan 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. Which is why we scope Pentewan projects parish-up, not template-down — the PL26 context shapes the design from day one. Whether the project is on planned harbour cottages in the centre or further out toward St Austell, the architectural design 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 an architectural design 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
Whether your project is permitted development, a householder application or full planning, the route through Cornwall Council shapes the drawings we prepare from day one.

How a Pentewan architectural design project runs.
Step 1
Brief and site visit
We meet on site, walk the plot and listen to how you want to live in the finished space.
Step 2
Feasibility and sketch options
Two or three design directions tested against budget, planning policy and site constraints.
Step 3
Concept refinement
We develop the chosen direction into a coordinated set of plans, elevations and sections.
Step 4
Planning submission
We submit the application, monitor it through validation and respond to any officer queries.
Step 5
Decision and next stage
On approval we move into building regulations and tender drawings.
Most architectural-only commissions run from a few weeks for small householder applications to several months for new builds and listed work.
FAQs
Pentewan Architectural Design — local questions answered.
- How much does a measured building survey cost in Pentewan?
- £450–£850 for a typical 3-bed house in Pentewan (PL26), including plans, sections and elevations. Larger properties and listed buildings quoted per site visit.
- How long does the survey take?
- Half a day on site for a standard house; drawings issued within 5–7 working days. Larger commercial jobs quoted separately.
- Do I need a measured survey for planning?
- Yes — Cornwall Council requires accurate existing plans/elevations for any householder application. A rough sketch will fail validation.
- Who do you usually work for in Pentewan?
- A genuine mix: owner-occupiers, second-home and holiday-let owners, small commercial clients and the occasional smallholding. That matters because the right route for an architectural design depends on how the property is used, not just what it looks like, so we scope from the use first.
- Do you produce building regulations drawings as well?
- Yes. Once planning is approved we prepare the full building regs package — sections, construction details, structural coordination and specification — drawn at 1:50 and 1:10 so the builder and building control have everything they need. In Pentewan specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- Can you handle a Certificate of Lawfulness instead?
- Yes — for permitted development work it's worth the small extra step. You get a formal council certificate confirming your build is lawful, which protects you on resale and is often required by mortgage lenders.

A proper Pentewan measured survey costs a fraction of the design fees it protects — and a rounding error at survey stage compounds into a build-cost variation later.
