Extensions for Summercourt (TR8)

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. Summercourt sits in Mid Cornwall, and that geography ends up in the drawings — Summercourt is a commuter village in the TR8 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward bungalows and older cottages.

Summercourt sits in Mid Cornwall — covering TR8 from Newquay, Cubert, Holywell Bay outward.

Our process

How a Summercourt 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 proof — We typically have one or two extension jobs live in the TR8 area at any time, so the local planning officers know our drawings on sight.

What we focus on

Extensions considerations specific to Summercourt.

  • 01

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

  • 02

    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.

  • 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

    Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.

Local context

Why Summercourt is its own job.

In Summercourt the planning picture is specific: applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. 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. That local reading is what makes a Summercourt (TR8) project different from a generic Cornwall scheme — and is the whole reason we work this way. On bungalows in particular — the kind you'll also find toward St Newlyn East — the extension brief always has to read the existing fabric first.

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.

Local fabric

One TR8 studio, one extension job — start to finish.

Building stock

Across Summercourt (TR8) we work on post-war semis, bungalows, modern estates, older cottages, garden infill plots. Each stock type drives a different extension response — bungalows in particular needs careful detailing here.

Parish & policy

Summercourt sits in the parish of Summercourt, 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 Summercourt site visits get booked within the same week.

FAQs

Summercourt Extensions — local questions answered.

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. In Summercourt 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.
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.
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.

Every Summercourt extension we work on is treated as a TR8 job in its own right — local fabric, local policy, local builders.
