Indian Queens extension — feasibility first, drawings second
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. In Indian Queens, that work is shaped by the place itself — Indian Queens is a substantial residential village on the A30 between Newquay and Bodmin, with strong commuter demand and significant recent estate expansion, with a building stock that leans toward Victorian terraces and individual self-build plots.
Indian Queens sits in Mid Cornwall — covering TR9 from St Columb Major outward.
- ✓ Plain-English feasibility before any drawings
- ✓ 30+ years of Cornwall Council approvals
- ✓ standard policy area experience built into the fee
- ✓ Cornwall Council regulars across every sub-area
Who this is for
Indian Queens runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every extension enquiry from the use-class up.

Indian Queens 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 Indian Queens 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 Indian Queens is its own job.
Locally, outside Conservation Area and AONB. A30 dualling has driven substantial residential expansion; St Enoder parish operates detailed input on edge-of-village sites. For extension specifically, Indian Queens sits outside the headline designations, which usually gives a slightly more flexible starting point — but parish-level character still matters. Which is why we scope Indian Queens projects parish-up, not template-down — the TR9 context shapes the design from day one. Whether the project is on Victorian terraces in the centre or further out toward St Columb Major, 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 Indian Queens.
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
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.
03
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
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 Indian Queens 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 TR9.
Building stock
Across Indian Queens (TR9) we work on Victorian terraces, post-war estates, modern Persimmon, Bellway and Wainhomes estates, individual self-build plots. Each stock type drives a different extension response — Victorian terraces in particular needs careful detailing here.
Parish & policy
Indian Queens sits in the parish of St Enoder, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover TR9 from our studio, with regular extension jobs also running in St Columb Major, St Stephen-in-Brannel. Most Indian Queens site visits get booked within the same week.
What does a first Indian Queens consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR9 plot and follow up with a written feasibility note inside a week — no obligation either way.
