Small rear extensions in Wadebridge — under-3m designs that work hard
A Wadebridge rear extension under 3m doesn't need to feel small. The compact PL27 terraces and cottages we work on benefit most from a single tight move: a glazed corner, a side-light over the new kitchen, or a re-jigged level threshold to the garden. Under-3m and single-storey usually sits inside permitted development, which removes most of the planning risk. 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. The way we approach extension in Wadebridge starts with a measured walk-round — Wadebridge is the inland market town for the Camel Estuary and Padstow, with a fifteenth-century bridge over the Camel, a strong independent retail high street and a busy Camel Trail terminus, with a building stock that leans toward Georgian townhouses and post-war suburban estates.
Wadebridge sits in North Cornwall — just off the A39; with Truro the closest city; 5 miles from Padstow.

Who this is for
In Wadebridge the extension brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Local context
Why Wadebridge is its own job.
Two things shape a Wadebridge application: parish character and policy. On policy — conservation Area covers the historic core and the bridge. Cornwall Council planning case load includes significant edge-of-town residential development pressure. For extension specifically, parts of Wadebridge sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. Get that local reading right and the rest of the Wadebridge programme tends to run on time. On Georgian townhouses in particular — the kind you'll also find toward Rock — 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.
What we focus on
Extensions considerations specific to Wadebridge.
01
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
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.
04
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.

How a Wadebridge 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.
FAQs
Wadebridge Extensions — local questions answered.
- What's the smallest worthwhile rear extension in Wadebridge?
- Anything from 8m² is worth doing if it unlocks a kitchen layout. Below that, the cost per m² makes a glazed door upgrade more sensible.
- Can I do a small extension in Wadebridge under permitted development?
- If the property has its PD rights intact, single-storey rear extensions up to 3m (terraced/semi) or 4m (detached) are permitted. Conservation Area sites lose this — full planning needed.
- How much does a small extension cost in Wadebridge?
- For 8–15m² in Wadebridge, allow £30k–£55k including a basic kitchen refit. Coastal detailing and salt-resistant ironmongery add 5–8%.
- 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. In Wadebridge specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.

Small extensions in Wadebridge succeed on detailing, not scale. A well-placed rooflight and the right floor finish often deliver more than an extra metre of footprint.
