Extensions Herodsfoot: PL14 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 Herodsfoot project we take on begins with reading the local context — Herodsfoot is a small rural hamlet in the PL14 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and small infill homes.

Herodsfoot sits in East Cornwall — covering PL14 from Looe, Duloe, Lanreath outward.

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

Local context

Why Herodsfoot is its own job.

The main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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 Herodsfoot application gets approved at eight weeks or stalls in committee. The cottages that dominate Herodsfoot (and continue out toward Lanreath) 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 Herodsfoot.

  • 01

    Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.

  • 02

    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.

  • 03

    Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.

  • 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 Herodsfoot extension project runs.

  1. Step 1

    Brief

    We meet on site, talk through how you live now and what's missing from the current layout.

  2. Step 2

    Design

    Two or three sketch directions with rough budgets, then refinement of the chosen route.

  3. Step 3

    Approvals

    Planning or Cert of Lawfulness, then a full building regs package.

  4. Step 4

    Build

    Either through your own builder with our drawings, or as a full build by our team.

  5. 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.

FAQs

Herodsfoot Extensions — local questions answered.

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. In Herodsfoot specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
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.
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.

Herodsfoot is part of Looe

Herodsfoot sits inside the Looe catchment — we cover both as one extension territory.
