Extensions Morval: PL13 planning, East Cornwall fabric
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. Every Morval project we take on begins with reading the local context — Morval is an estate-influenced village in the PL13 area, with designed landscape, older cottages and rural edges close together, with a building stock that leans toward detached homes and farm buildings.
Morval sits in East Cornwall — covering PL13 from Looe, Duloe, Herodsfoot outward.
- Rural / open-countryside policy area
- ✓ 30+ years of Cornwall Council approvals
- ✓ Cornwall Council regulars across every sub-area
- ✓ One studio — design, planning and build under one roof
- ✓ Local to East Cornwall — not a national franchise
Local proof — Most Morval homeowners come to us after a extension quote elsewhere felt vague on planning — we lead with feasibility instead.

Why Morval is its own job.
Landscape setting, curtilage history and estate character need a precise design rationale rather than a standard suburban approach. That sets the scene before any design work begins. 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. It's the kind of detail that decides whether a Morval application gets approved at eight weeks or stalls in committee. The detached homes that dominate Morval (and continue out toward Herodsfoot) set the tone for any extension scheme here.
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 Morval.
01
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
02
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
03
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.
04
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
Our process
How a Morval 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 East Cornwall studio is the right fit for Morval extension.
Building stock
Across Morval (PL13) we work on estate cottages, farm buildings, detached homes, converted outbuildings, small infill plots. Each stock type drives a different extension response — detached homes in particular needs careful detailing here.
Parish & policy
Morval sits in the parish of Morval, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover PL13 from our studio, with regular extension jobs also running in Looe, Duloe, Herodsfoot. Most Morval site visits get booked within the same week.
How quickly can you visit a Morval site?
Usually within the same week. Morval (PL13) is on our regular East Cornwall run, alongside Looe, Duloe, Herodsfoot. First visits are free and you'll get an honest feasibility view inside seven days.

Morval Extensions — local questions answered.
- 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. In Morval specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- 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.
Morval is part of Looe
Morval sits inside the Looe catchment — we cover both as one extension territory.
