Threemilestone planning — a Mid Cornwall studio
We prepare and submit planning applications to Cornwall Council and, where relevant, the Isles of Scilly authority — handling drawings, statements, validation queries and officer negotiation from start to determination. In Threemilestone, that work is shaped by the place itself — Threemilestone is the western residential and retail-park suburb of Truro, with the West Cornwall Hospital site nearby and significant new estate development on the Langarth Garden Village land, with a building stock that leans toward 1970s and 1980s estates and office and retail conversions.
Threemilestone sits in Mid Cornwall — just off the A390; covering TR3 from Truro, Shortlanesend, Playing Place outward.

Page purpose
What you actually get on a Threemilestone planning application drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR3 address, not a build contract. For most Threemilestone 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 TR3 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 Threemilestone

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.

Common Threemilestone pitfalls we plan around.

Trussed roofs and shallow foundations in the later TR3 estates, which change the structural strategy
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 planning application enquiry does not get passed between firms.
- Applications for Threemilestone are handled through Cornwall Council, with St Austell the nearest planning office we deal with regularly.
- Design and build are offered from the same studio, which means the person answering your Threemilestone 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
Planning considerations specific to Threemilestone.
01
Tree Preservation Orders, ecology surveys and neighbour consultation responses can change the validation list mid-application.
02
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
03
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
04
Cornwall has more than thirty Conservation Areas and large stretches of AONB; planning weight on materials, mass and form is significantly higher in those zones.

Local context
Why Threemilestone is its own job.
The planning backdrop in Mid Cornwall is real, not abstract: outside Conservation Area and AONB. Langarth Garden Village (3,500+ homes) is reshaping the west of Truro with strict design code expectations on adjacent sites. For planning application specifically, Threemilestone sits outside the headline designations, which usually gives a slightly more flexible starting point — but parish-level character still matters. Treat the TR3 parish brief as the design brief and the Threemilestone application has somewhere to land. Whether the project is on 1970s and 1980s estates in the centre or further out toward Chacewater, the planning application response is locally tuned.
Planning note
Cornwall Council's planning team is among the busiest in the South West. A clean, well-documented submission moves through validation faster than a bare-minimum one.
Our process
How a Threemilestone planning application project runs.
Step 1
Initial review
We assess constraints — Conservation Area, AONB, listed status, Article 4, TPOs, flood zone.
Step 2
Strategy
We recommend the right application type and likely fee, programme and supporting documents.
Step 3
Drawing and statement preparation
Plans, elevations, sections, block and location plans, plus DAS and any heritage or ecology input.
Step 4
Submission and validation
We upload to the Planning Portal, pay the council fee on your behalf and respond to validation requests.
Step 5
Determination
We monitor consultation, respond to officer queries and negotiate amendments where it improves the chances of approval.
Householder applications are typically eight to twelve weeks from validation; full planning runs thirteen to sixteen weeks; major or contentious schemes can take longer.
FAQs
Threemilestone Planning — local questions answered.
- We live in the house. Can a planning application in Threemilestone 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 Threemilestone are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- Do you handle listed building consent?
- Yes. Listed Building Consent runs alongside planning where works affect a listed structure, including some interior alterations. The drawing detail and Heritage Statement are fundamentally different from a standard planning pack. In Threemilestone specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- How much does a planning application cost in Cornwall?
- Cornwall Council charges a fixed national fee — currently £258 for a householder application and £578 for a single new dwelling. Our fee for the drawings, statements and submission sits separately and depends on project complexity.
- What if the council asks for more information after submission?
- Common, and usually fixable. Validation requests, ecology comments, highways queries and design tweaks all get handled by us inside the application — no extra fee unless the scope changes substantially.
- Do I need to consult my neighbours before applying?
- You don't have to — the council formally consults them — but a quiet conversation early on usually pays off. Objections from neighbours are weighed by the planning officer and can be the deciding factor on borderline schemes.
- What's the difference between full planning and householder?
- Householder covers extensions, outbuildings and alterations to a single dwelling. Full planning is needed for new dwellings, change of use, and anything affecting curtilage subdivision. We'll confirm which route fits at first review.
Threemilestone is part of Truro
Threemilestone sits inside the Truro catchment — we cover both as one planning application territory.

Follow the chain: survey, drawings, build
Threemilestone is covered from our Truro run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
