Pillaton extensions — a East Cornwall studio
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. Anchor any Pillaton extension in the local fabric and the rest follows — Pillaton is a rural parish in the PL12 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward farmhouses and converted barns.
Pillaton sits in East Cornwall — covering PL12 from Saltash, Hatt, Landrake outward.

Who this is for
Pillaton runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every extension enquiry from the use-class up.
Local watch-list
What usually catches extension projects out in Pillaton.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
Local proof — We typically have one or two extension jobs live in the PL12 area at any time, so the local planning officers know our drawings on sight.

Pillaton Extensions — local questions answered.
- 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. In Pillaton specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- How much does an extension cost in Cornwall?
- Build costs in Cornwall typically run from around £2,200 to £3,200 per square metre for a good-quality single-storey extension, more for kitchen-grade fit-out or complex glazing. We give a realistic budget before drawings start, not after.
- 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.
Local context
Why Pillaton is its own job.
The planning backdrop in East Cornwall is real, not abstract: open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. 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. Treat the PL12 parish brief as the design brief and the Pillaton application has somewhere to land. Whether the project is on farmhouses in the centre or further out toward Saltash, the extension response is locally tuned.
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 Pillaton.
01
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
02
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
03
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
04
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.
Our process
How a Pillaton 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
Why Pillaton homeowners pick a local studio for extension.
Building stock
Across Pillaton (PL12) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different extension response — farmhouses in particular needs careful detailing here.
Parish & policy
Pillaton sits in the parish of Pillaton, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover PL12 from our studio, with regular extension jobs also running in Saltash, Hatt, Landrake. Most Pillaton site visits get booked within the same week.
What does a first Pillaton consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL12 plot and follow up with a written feasibility note inside a week — no obligation either way.
