Architectural Design Altarnun: PL15 planning, East Cornwall fabric
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. Every Altarnun project we take on begins with reading the local context — Altarnun is a moorland-edge hamlet in the PL15 area, where exposed weather, narrow lanes and rural character set the brief, with a building stock that leans toward farm buildings and stone cottages.
Altarnun sits in East Cornwall — covering PL15 from Launceston, Warbstow, North Petherwin outward.

Local proof — Our East Cornwall workload means a Altarnun architectural design project never has to wait for an out-of-county team to drive down.

Why Altarnun is its own job.
Rural policy, landscape impact and services such as drainage are usually the key constraints, especially outside settlement boundaries. That sets the scene before any design work begins. For architectural design specifically, parts of Altarnun sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Altarnun application gets approved at eight weeks or stalls in committee. The farm buildings that dominate Altarnun (and continue out toward North Petherwin) set the tone for any architectural design scheme here.
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.
What we focus on
Architectural Design considerations specific to Altarnun.
01
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
02
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
03
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
04
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
Our process
How a Altarnun 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.
Local fabric
Choosing a architectural design team that actually knows PL15.
Building stock
Across Altarnun (PL15) we work on stone cottages, farm buildings, isolated houses, converted barns, small rural infill. Each stock type drives a different architectural design response — farm buildings in particular needs careful detailing here.
Parish & policy
Altarnun sits in the parish of Altarnun, which matters for how parish-level consultation lands on a architectural design application.
Coverage
We cover PL15 from our studio, with regular architectural design jobs also running in Launceston, Warbstow, North Petherwin. Most Altarnun site visits get booked within the same week.
How quickly can you visit a Altarnun site?
Usually within the same week. Altarnun (PL15) is on our regular East Cornwall run, alongside Launceston, Warbstow, North Petherwin. First visits are free and you'll get an honest feasibility view inside seven days.

Altarnun Architectural Design — local questions answered.
- 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. In Altarnun specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- How long does a planning application take in Cornwall?
- Householder applications are decided in eight weeks from validation in most cases; full planning runs to thirteen weeks. Validation itself can take one to three weeks at Cornwall Council depending on workload, so plan for around three to four months from drawing start to decision.
- What happens if planning is refused?
- We review the officer's reasons, advise honestly on the strength of an appeal, and where a redesign is the better route, prepare a revised scheme. The free re-submission window inside twelve months can be used strategically.
- Will you visit the site before designing?
- Always. Cornish sites have wind, light, slope and access quirks that don't show up on a Google Street View. A site visit is built into every fee proposal.
- Do I need planning permission or is it permitted development?
- It depends on the property, the size and position of the works, and whether you are in a Conservation Area, AONB or Article 4 area. We'll review your address against the General Permitted Development Order at first consultation and tell you straight.
Altarnun is part of Launceston
Altarnun sits inside the Launceston catchment — we cover both as one architectural design territory.
