Extensions Rejerrah: TR8 planning, North 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 Rejerrah project we take on begins with reading the local context — Rejerrah is a small rural hamlet in the TR8 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward small infill homes and bungalows.

Rejerrah sits in North Cornwall — covering TR8 from Newquay, Cubert, Holywell Bay 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 North Cornwall — not a national franchise

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

Local context

Why Rejerrah 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 Rejerrah application gets approved at eight weeks or stalls in committee. The small infill homes that dominate Rejerrah (and continue out toward Holywell Bay) 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 Rejerrah.

  • 01

    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.

  • 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

    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 Rejerrah 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.

Local fabric

Why a North Cornwall studio is the right fit for Rejerrah extension.

Building stock

Across Rejerrah (TR8) we work on cottages, farmhouses, converted barns, bungalows, small infill homes. Each stock type drives a different extension response — small infill homes in particular needs careful detailing here.

Parish & policy

Rejerrah sits in the parish of Rejerrah, which matters for how parish-level consultation lands on a extension application.

Coverage

We cover TR8 from our studio, with regular extension jobs also running in Newquay, Cubert, Holywell Bay. Most Rejerrah site visits get booked within the same week.

How quickly can you visit a Rejerrah site?

Usually within the same week. Rejerrah (TR8) is on our regular North Cornwall run, alongside Newquay, Cubert, Holywell Bay. First visits are free and you'll get an honest feasibility view inside seven days.

FAQs

Rejerrah 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 Rejerrah 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.
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.

Rejerrah is part of Newquay

Rejerrah sits inside the Newquay catchment — we cover both as one extension territory.
