Menheniot 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 Menheniot extension in the local fabric and the rest follows — Menheniot is a rural parish in the PL14 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward rural cottages and converted barns.
Menheniot sits in East Cornwall — covering PL14 from Liskeard, Dobwalls, St Cleer outward.

Who this is for
Menheniot runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every extension enquiry from the use-class up.

Tighter Local Plan tests on isolated rural dwellings
Local proof — Most Menheniot homeowners come to us after a extension quote elsewhere felt vague on planning — we lead with feasibility instead.

Menheniot 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 Menheniot specifically, we'd start by checking the latest parish-level planning history 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.
- 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.
- 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 Menheniot is its own job.
Locally, open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. For extension specifically, 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 Menheniot projects parish-up, not template-down — the PL14 context shapes the design from day one. Whether the project is on rural cottages in the centre or further out toward Liskeard, 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 Menheniot.
01
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
02
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
03
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
04
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 Menheniot 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 PL14.
Building stock
Across Menheniot (PL14) we work on farmhouses, converted barns, rural cottages, smallholdings, scattered modern homes. Each stock type drives a different extension response — rural cottages in particular needs careful detailing here.
Parish & policy
Menheniot sits in the parish of Menheniot, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover PL14 from our studio, with regular extension jobs also running in Liskeard, Dobwalls, St Cleer. Most Menheniot site visits get booked within the same week.
What does a first Menheniot consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a PL14 plot and follow up with a written feasibility note inside a week — no obligation either way.

Menheniot sits inside the Liskeard catchment — we cover both as one extension territory.
