Mylor Bridge 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. Anchor any Mylor Bridge extension in the local fabric and the rest follows — Mylor Bridge is an AONB creek-side village between Falmouth and Penryn, with Mylor Yacht Harbour nearby and a strong period property market, with a building stock that leans toward traditional creekside cottages and modern high-end coastal homes.
Mylor Bridge sits in South Cornwall — covering TR11 from Penryn outward.

Local proof — Most Mylor Bridge extension clients we work with are second-time builders — they've seen the templated approach fail once already.

Mylor Bridge Extensions — local questions answered.
- 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. In Mylor Bridge specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- 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.
Local context
Why Mylor Bridge is its own job.
Locally, conservation Area covers the village core including Lemon Hill and the bridge; AONB across the parish. Creek views and ecology constraints weigh on most riverside schemes. For extension specifically, parts of Mylor Bridge 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 Mylor Bridge drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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. Which is why we scope Mylor Bridge projects parish-up, not template-down — the TR11 context shapes the design from day one. Whether the project is on traditional creekside cottages in the centre or further out toward Falmouth, 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 Mylor Bridge.
01
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
02
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
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.
Our process
How a Mylor Bridge 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
Why a South Cornwall studio is the right fit for Mylor Bridge extension.
Building stock
Across Mylor Bridge (TR11) we work on traditional creekside cottages, Victorian villas, Edwardian houses on Comfort Road, modern high-end coastal homes. Each stock type drives a different extension response — traditional creekside cottages in particular needs careful detailing here.
Parish & policy
Mylor Bridge sits in the parish of Mylor, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover TR11 from our studio, with regular extension jobs also running in Penryn, Falmouth, Feock. Most Mylor Bridge site visits get booked within the same week.
What does a first Mylor Bridge consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR11 plot and follow up with a written feasibility note inside a week — no obligation either way.
