Design, planning and build for Bolingey extension
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. A TR6 site visit comes before a Bolingey sketch, every time — Bolingey is a small rural hamlet in the TR6 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward bungalows and converted barns.
Bolingey sits in North Cornwall — covering TR6 from Perranporth, Goonhavern, Rose outward.
- Rural / open-countryside policy area
- ✓ Cornwall Council regulars across every sub-area
- ✓ rural policy area experience built into the fee
- ✓ Local to North Cornwall — not a national franchise
- ✓ Same team on paper as on site
Local proof — Our North Cornwall workload means a Bolingey extension project never has to wait for an out-of-county team to drive down.

Why Bolingey is its own job.
Cornwall Council's lens on Bolingey is consistent: the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. That's why we treat every Bolingey project as a TR6-area job first — not a generic Cornwall job with a postcode bolted on. The bungalows that dominate Bolingey (and continue out toward Rose) 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 Bolingey.
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
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
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 Bolingey 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 TR6.
Building stock
Across Bolingey (TR6) 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
Bolingey sits in the parish of Bolingey, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover TR6 from our studio, with regular extension jobs also running in Perranporth, Goonhavern, Rose. Most Bolingey site visits get booked within the same week.
How quickly can you visit a Bolingey site?
Usually within the same week. Bolingey (TR6) is on our regular North Cornwall run, alongside Perranporth, Goonhavern, Rose. First visits are free and you'll get an honest feasibility view inside seven days.

Bolingey Extensions — local questions answered.
- 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. In Bolingey 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.
- 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.
- 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.
Bolingey is part of Perranporth
Bolingey sits inside the Perranporth catchment — we cover both as one extension territory.
