Extensions Washaway: PL30 planning, North Cornwall fabric
Extensions are the bread and butter of Cornish homes — adding the kitchen-diner the original layout never had, the bedroom for a growing family, or the light and views the back of the house should always have had. What works on a PL30 plot rarely works elsewhere — Washaway is a small rural hamlet in the PL30 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward bungalows and converted barns.
Washaway sits in North Cornwall — covering PL30 from Bodmin, St Breward, Nanstallon outward.
- Rural / open-countryside policy area
- ✓ Plain-English feasibility before any drawings
- ✓ rural policy area experience built into the fee
- ✓ One studio — design, planning and build under one roof
- ✓ Local to North Cornwall — not a national franchise
Local proof — Our North Cornwall workload means a Washaway extension project never has to wait for an out-of-county team to drive down.

Why Washaway is its own job.
The main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. That sets the scene before any design work begins. For extension specifically, 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 Washaway application gets approved at eight weeks or stalls in committee. The bungalows that dominate Washaway (and continue out toward Nanstallon) set the tone for any extension scheme here.
Planning note
Most extensions in Cornwall are either permitted development or a straightforward householder application — but Conservation Area and AONB sites need a more careful design conversation upfront.
What we focus on
Extensions considerations specific to Washaway.
01
Extensions over a certain proportion of the original house trigger full Part L upgrade obligations to the existing building — worth knowing before brief is set.
02
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
03
Permitted development for rear extensions runs to four metres on a detached house, three on a semi or terrace — but Article 4 areas remove this in some parishes.
04
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
Our process
How a Washaway extension project runs.
Step 1
Brief
We meet on site, talk through how you live now and what's missing from the current layout.
Step 2
Design
Two or three sketch directions with rough budgets, then refinement of the chosen route.
Step 3
Approvals
Planning or Cert of Lawfulness, then a full building regs package.
Step 4
Build
Either through your own builder with our drawings, or as a full build by our team.
Step 5
Handover
Snag, certify, hand over the keys to your new space.
Typical single-storey rear extensions run twelve to twenty weeks on site; two-storey and wraparound projects sixteen to thirty weeks.
Local fabric
Choosing a extension team that actually knows PL30.
Building stock
Across Washaway (PL30) we work on cottages, farmhouses, converted barns, bungalows, small infill homes. Each stock type drives a different extension response — bungalows in particular needs careful detailing here.
Parish & policy
Washaway sits in the parish of Washaway, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover PL30 from our studio, with regular extension jobs also running in Bodmin, St Breward, Nanstallon. Most Washaway site visits get booked within the same week.
How quickly can you visit a Washaway site?
Usually within the same week. Washaway (PL30) is on our regular North Cornwall run, alongside Bodmin, St Breward, Nanstallon. First visits are free and you'll get an honest feasibility view inside seven days.

Washaway Extensions — local questions answered.
- Will my house be liveable during the build?
- For most rear and side extensions, yes — we sequence the works so the kitchen and one bathroom stay functional until the new build is watertight and connected. In Washaway specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- How long does the whole process take?
- Allow roughly three months for design and approvals, then twelve to twenty weeks on site for a typical single-storey extension. Wraparounds and two-storey add-ons take longer, mostly through approval and groundworks.
- Can you handle the build as well as the design?
- Yes — that's the whole point of the studio. One contract, one point of contact, no finger-pointing between architect and builder when something needs a decision on site.
- What about the Party Wall Act?
- If you share a wall with a neighbour or build close to a boundary, the Act applies. We flag it early, recommend a surveyor and keep the programme aligned with the notice period.
Washaway is part of Bodmin
Washaway sits inside the Bodmin catchment — we cover both as one extension territory.

Designing a extension in Washaway is as much about reading the parish as reading the brief; we do both, and the planning outcomes follow.
