Design, planning and build for Kuggar extension
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. What works on a TR12 plot rarely works elsewhere — Kuggar is a coastal village in the TR12 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward bungalows and holiday homes.
Kuggar sits in Lizard Peninsula — covering TR12 from The Lizard, Ruan Minor, Cadgwith outward.

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

Why Kuggar is its own job.
Cornwall Council's lens on Kuggar is consistent: coastal setting and landscape sensitivity mean rooflines, glazing, drainage and external materials need careful handling from the first sketch. For extension specifically, the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Kuggar drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Kuggar project as a TR12-area job first — not a generic Cornwall job with a postcode bolted on. The bungalows that dominate Kuggar (and continue out toward Cadgwith) 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 Kuggar.
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
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
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 Kuggar 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 Kuggar homeowners pick a local studio for extension.
Building stock
Across Kuggar (TR12) we work on granite cottages, rendered coastal houses, holiday homes, bungalows, replacement dwellings. Each stock type drives a different extension response — bungalows in particular needs careful detailing here.
Parish & policy
Kuggar sits in the parish of Kuggar, which matters for how parish-level consultation lands on a extension application.
Coverage
We cover TR12 from our studio, with regular extension jobs also running in The Lizard, Ruan Minor, Cadgwith. Most Kuggar site visits get booked within the same week.
How quickly can you visit a Kuggar site?
Usually within the same week. Kuggar (TR12) is on our regular Lizard Peninsula run, alongside The Lizard, Ruan Minor, Cadgwith. First visits are free and you'll get an honest feasibility view inside seven days.

Kuggar 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 Kuggar specifically, we'd start by checking AONB landscape sensitivity 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.
- 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.
Kuggar is part of The Lizard
Kuggar sits inside the The Lizard catchment — we cover both as one extension territory.
