Extensions designed around Gorran Haven
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. Reading Gorran Haven on the ground is half of the extension job — Gorran Haven is an AONB south coast cove village south of Mevagissey, with a tight Conservation Area at the harbour and a network of cliff paths to Dodman Point, with a building stock that leans toward Victorian villas and modern carefully detailed coastal homes.
Gorran Haven sits in South Cornwall — just off the A39; covering PL26 from Pentewan outward.

Who this is for
In Gorran Haven the extension brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Page purpose
Drawings only, or drawings through to handover in Gorran Haven?
Both routes are open on a PL26 project, and the honest answer depends on whether you already have a builder you trust. Plenty of Gorran Haven clients take the drawings, tender them locally, then come back to us for the build if the numbers do not stack up.
- Route one: feasibility, planning and a tender-ready technical pack
- Route two: the same pack, then the build under one contract
- Either way the survey and feasibility work is identical, so the decision can wait
- Fees quoted per stage against the PL26 scope, not as one opaque figure

Local context
Why Gorran Haven is its own job.
Around Gorran Haven (PL26), conservation Area covers the harbour village; AONB and Heritage Coast across the parish. Coastal margin and cliff sites face strict controls; Dodman Point conservation considerations apply nearby. For extension specifically, parts of Gorran Haven sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Gorran Haven drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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. Reading Gorran Haven properly up front saves more time than any drawing tool ever will. Most of our extension work in Gorran Haven lands on Victorian villas, with detailing that has to nod to the wider Mevagissey streetscape. On older stock, the practical constraint is usually joinery, render and roof line rather than the extension itself. We draw those details out early so an extension submission is not sent back for missing information. Confirm listing status with the local planning authority before assuming permitted development. Exposure is the real design driver near the water: wind-driven rain, salt and driving damp push detailing towards better weathering, sheltered openings and robust fixings. Where an AONB or coastal policy applies, visual impact usually carries more weight than size.
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 Gorran Haven.
01
Wind and sea-spray exposure can drive material choices on west-facing extensions; we detail accordingly.
02
Drainage on older Cornish properties is rarely on a clean modern map; CCTV survey before design is often money well spent.
03
Cornish granite and slate-hung walls react differently to new openings than modern brickwork — lintel choice and structural sequencing matter.
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.

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

FAQs
Gorran Haven Extensions — local questions answered.
- 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. In Gorran Haven specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- 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.
- 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.
- We live in the house. Can an extension in Gorran Haven be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Gorran Haven are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
Local proof — We typically have one or two extension jobs live in the PL26 area at any time, so the local planning officers know our drawings on sight.
