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 — just off the A38; covering PL14 from Liskeard, Dobwalls, St Cleer outward.

Who this is for
In Menheniot 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 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.
- We live in the house. Can a extension in Menheniot be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Menheniot are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Who this is for
Why this page exists, and who it is for
- Design and build are offered from the same studio, which means the person answering your Menheniot questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a extension enquiry does not get passed between firms.
- Applications for Menheniot are handled through Cornwall Council, with Liskeard the nearest planning office we deal with regularly.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.

Follow the chain: survey, drawings, build
Menheniot is covered from our Liskeard run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
Drawings only, or drawings through to handover in Menheniot?
Both routes are open on a PL14 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Menheniot clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the PL14 scope, not as one opaque figure

Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
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.

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.
