Extensions for Bude (EX23)
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. Bude sits in North Cornwall, and that geography ends up in the drawings — Bude is the principal town of the far north coast, with a Victorian sea pool, broad surf beaches at Summerleaze and Crooklets, and a Conservation Area covering the canal and the older town centre, with a building stock that leans toward Edwardian villas and modern Persimmon-style estates.
Bude sits in North Cornwall — just off the A39; with Truro the closest city.

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

Extensions considerations specific to Bude.
01
Bude EX23 addresses fall under Cornwall Council's North sub-area, so pre-application advice comes from the Bodmin office — slower turnaround than the Truro side, worth building into the programme.
02
Sea-facing extensions in Bude need wind-load uplift checks on roofs and Class 4 weather-tightness on windows; we specify accordingly rather than copying an inland detail.
03
Flood Zone 2 catches parts of the lower town near the canal and Summerleaze — a flood risk statement is often required even for modest rear extensions in those streets.
04
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
05
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.
06
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.
07
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
Local context
Why Bude is its own job.
In Bude the planning picture is specific: conservation Area covers the canal, the seafront and parts of the town centre. AONB and Heritage Coast across most of the parish boundary. Edge-of-town residential growth is significant. For extension specifically, parts of Bude 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 Bude drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That local reading is what makes a Bude (EX23) project different from a generic Cornwall scheme — and is the whole reason we work this way. On Edwardian villas in particular — the kind you'll also find toward North Cornwall — the extension brief always has to read the existing fabric first. Bude sits inside the Cornwall AONB and the North Cornwall Heritage Coast, so extensions facing the sea — particularly anything visible from the South West Coast Path or the canal corridor — get close landscape-impact scrutiny. Conservation Area boundaries through the canal, The Strand and parts of Belle Vue catch most pre-1960s properties; the post-war and Persimmon-era estates behind Stratton Road usually fall outside, which materially changes the planning route. Atlantic exposure also drives detailing: render specs, fixings and timber treatments here all need to be specified for a coastal Zone 4 wind load, not a sheltered inland site.
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.

Local fabric
One EX23 studio, one extension job — start to finish.
Building stock
Across Bude (EX23) we work on Victorian seaside houses, Edwardian villas, post-war estates, modern Persimmon-style estates, architect-designed coastal homes at Maer Cliff. Each stock type drives a different extension response — Edwardian villas in particular needs careful detailing here.
Parish & policy
Bude is its own town in North Cornwall, with planning history that's specific to the EX23 catchment.
Coverage
We cover EX23 from our studio, with regular extension jobs also running in North Cornwall. Most Bude site visits get booked within the same week.
Can you handle both planning and build in Bude?
Yes — design, planning, building regs and full construction run under one roof. For clients with an existing Bude builder we can stop at a tender-ready Full Plans pack instead.

In Bude 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.
FAQs
Bude Extensions — local questions answered.
- Do extensions in Bude need extra planning consideration because of the AONB?
- Yes — Bude is inside the Cornwall AONB, so any extension visible in long views from the coast path, beaches or canal carries an extra landscape-impact test. Single-storey rear extensions tucked behind the existing house are usually fine; two-storey side or sea-facing additions need a more careful design conversation and often a Landscape and Visual Impact note.
- Are extensions in the Bude Conservation Area harder to get approved?
- Not harder, but more design-led. The Bude Canal, Strand and Belle Vue conservation zones expect render colours, sash proportions, slate or natural-slate-equivalent roofing and restrained glazing. Article 4 directions in parts of the centre remove some permitted development rights, so we always check the address before committing to a route.
- How do you handle coastal exposure on Bude extensions?
- We design to the actual EX23 wind and driving-rain exposure: stainless or A4 fixings, high-performance render systems, factory-finished timber or aluminium-clad windows, and roof detailing that copes with uplift. Costs a little more up-front but avoids the ten-year repaint and resealing cycle you see on standard inland specs.
- Can you build extensions in Bude, or just design them?
- Both. We run full-build extensions across EX23 — Bude, Stratton, Poughill, Marhamchurch and Widemouth Bay — from our own team, with the same studio handling design, planning and construction. One contract, one site manager, one point of contact.
- 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. In Bude specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
