One studio for extension in Pelynt
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. Pelynt sits in East Cornwall, and that geography ends up in the drawings — Pelynt is a rural parish in the PL13 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward rural cottages and scattered modern homes.
Pelynt sits in East Cornwall — covering PL13 from Looe, Duloe, Herodsfoot outward.

Our process
How a Pelynt 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 proof — Most Pelynt extension clients we work with are second-time builders — they've seen the templated approach fail once already.

Extensions considerations specific to Pelynt.
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
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
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
Local context
Why Pelynt is its own job.
Two things shape a Pelynt application: parish character and policy. On policy — 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. Get that local reading right and the rest of the Pelynt programme tends to run on time. On rural cottages in particular — the kind you'll also find toward Lanreath — the extension brief always has to read the existing fabric first.
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.

Tighter Local Plan tests on isolated rural dwellings
Pelynt is part of Looe
Pelynt sits inside the Looe catchment — we cover both as one extension territory.

One PL13 studio, one extension job — start to finish.
Building stock
Across Pelynt (PL13) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different extension response — rural cottages in particular needs careful detailing here.
Parish & policy
Pelynt sits in the parish of Pelynt, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover PL13 from our studio, with regular extension jobs also running in Looe, Duloe, Herodsfoot. Most Pelynt site visits get booked within the same week.
Can you handle both planning and build in Pelynt?

FAQs
Pelynt Extensions — local questions answered.
- How much does an extension cost in Pelynt?
- 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. In Pelynt specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- Do I need planning permission for an extension?
- Often no — single-storey rear extensions, side extensions and modest two-storey additions can sit inside permitted development on a typical detached house. Conservation Areas, AONB and Article 4 zones remove some of those rights, so we always check the address first.
- 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.
