Orangery or extension in Looe — which one actually wins?
Orangery versus extension in Looe nearly always comes down to whether you want the room to be a genuine year-round living space or a lantern-lit garden room. Modern orangeries are thermally competent but rarely match a well-insulated flat-roof extension for winter comfort. On medieval and Georgian harbour cottages, we typically recommend the extension route unless a specific design language calls for the orangery. 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 PL13 site visit comes before a Looe sketch, every time — Looe is a working fishing town and seaside resort split by the Looe River into East and West Looe, with one of Cornwall's largest fishing fleets and a substantial Conservation Area covering both halves, with a building stock that leans toward Edwardian villas above the town and Victorian guesthouses.
Looe sits in East Cornwall — covering PL13 from Polperro, Duloe, Talland outward.
- Conservation Area
- Cornwall AONB
- Coastal exposure zone
- ✓ Orangery: £42k–£65k built
- ✓ Equivalent extension: £45k–£70k
- ✓ Extension usually wins on year-round use
- ✓ PD route usually the same for both
Who this is for
Looe runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every extension enquiry from the use-class up.

Looe Extensions — local questions answered.
- Is an orangery cheaper than an extension in Looe?
- Marginally — expect £42k–£65k for a 15–20m² orangery vs £45k–£70k for the equivalent extension. Difference disappears once you factor in heating costs.
- Do orangeries need planning in Looe?
- Yes — Conservation Area removes orangery PD. Same rules as a rear extension.
- Does an orangery add house value in Looe?
- Yes, but slightly less than a solid-walled extension per m². Buyers value year-round usability.
- 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 Looe specifically, we'd start by checking the Conservation Area boundary 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.
Local context
Why Looe is its own job.
Cornwall Council's lens on Looe is consistent: conservation Area covers both East and West Looe historic cores; AONB across the wider parish. Flood Zone 3 designation affects substantial parts of the harbour and town. For extension specifically, parts of Looe sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Looe drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Looe project as a PL13-area job first — not a generic Cornwall job with a postcode bolted on. The Edwardian villas above the town that dominate Looe (and continue out toward Talland) 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 Looe.
01
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
02
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
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.
Our process
How a Looe 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.

Building stock
Across Looe (PL13) we work on medieval and Georgian harbour cottages, Victorian guesthouses, Edwardian villas above the town, modern coastal homes at Hannafore. Each stock type drives a different extension response — Edwardian villas above the town in particular needs careful detailing here.

Nine times out of ten in Looe, a well-designed flat-roof extension beats an orangery on comfort, cost and resale — but the tenth home has a reason for the orangery, and we design for that too.
