Sennen architectural design — a Penwith studio
We prepare site-specific concept design, planning drawings and supporting documents that give your project the strongest possible chance of consent — and a clear path through Cornwall Council's planning process. In Sennen, that work is shaped by the place itself — Sennen is the most westerly mainland village, on the cliffs above Sennen Cove and the white-sand beach of Whitesand Bay, AONB-designated and entirely within Heritage Coast, with a building stock that leans toward granite cliff cottages and modern AONB-sensitive replacement dwellings.
Sennen sits in Penwith — covering TR19 from St Just in Penwith, Porthcurno outward.
- Conservation Area
- Cornwall AONB
- Coastal exposure zone
- Rural / open-countryside policy area
- ✓ Plain-English feasibility before any drawings
- ✓ 30+ years of Cornwall Council approvals
- ✓ One studio — design, planning and build under one roof
- ✓ Local to Penwith — not a national franchise
Local proof — We typically have one or two architectural design jobs live in the TR19 area at any time, so the local planning officers know our drawings on sight.

Why Sennen is its own job.
The planning backdrop in Penwith is real, not abstract: conservation Area covers Sennen churchtown and the cove; AONB and Heritage Coast across the parish. Cliff-edge sites face strict controls on materials and ridge heights. For architectural design specifically, parts of Sennen 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 Sennen 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. Treat the TR19 parish brief as the design brief and the Sennen application has somewhere to land. Whether the project is on granite cliff cottages in the centre or further out toward Porthcurno, the architectural design response is locally tuned.
Planning note
Whether your project is permitted development, a householder application or full planning, the route through Cornwall Council shapes the drawings we prepare from day one.
What we focus on
Architectural Design considerations specific to Sennen.
01
Listed buildings and curtilage structures need a separate Listed Building Consent application, drawn at a level of detail beyond standard planning.
02
Highways, drainage and ecology consultees can quietly determine an outcome long before the planning officer does.
03
Pre-application advice often saves months on contentious sites; we factor it into the programme where it adds value.
04
Cornwall Council planning officers expect drawings that respond to the local vernacular — slate, render, granite, timber — rather than generic suburban detailing.
Our process
How a Sennen architectural design project runs.
Step 1
Brief and site visit
We meet on site, walk the plot and listen to how you want to live in the finished space.
Step 2
Feasibility and sketch options
Two or three design directions tested against budget, planning policy and site constraints.
Step 3
Concept refinement
We develop the chosen direction into a coordinated set of plans, elevations and sections.
Step 4
Planning submission
We submit the application, monitor it through validation and respond to any officer queries.
Step 5
Decision and next stage
On approval we move into building regulations and tender drawings.
Most architectural-only commissions run from a few weeks for small householder applications to several months for new builds and listed work.
Local fabric
Why Sennen homeowners pick a local studio for architectural design.
Building stock
Across Sennen (TR19) we work on granite cliff cottages, Edwardian guesthouses, 1960s coastal bungalows, modern AONB-sensitive replacement dwellings. Each stock type drives a different architectural design response — granite cliff cottages in particular needs careful detailing here.
Parish & policy
Sennen is its own town in Penwith, with planning history that's specific to the TR19 catchment.
Coverage
We cover TR19 from our studio, with regular architectural design jobs also running in St Just in Penwith, Porthcurno, St Buryan. Most Sennen site visits get booked within the same week.
What does a first Sennen consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR19 plot and follow up with a written feasibility note inside a week — no obligation either way.

Sennen Architectural Design — local questions answered.
- Do you produce building regulations drawings as well?
- Yes. Once planning is approved we prepare the full building regs package — sections, construction details, structural coordination and specification — drawn at 1:50 and 1:10 so the builder and building control have everything they need. In Sennen specifically, we'd start by checking the Conservation Area boundary before committing to a direction.
- How long does a planning application take in Cornwall?
- Householder applications are decided in eight weeks from validation in most cases; full planning runs to thirteen weeks. Validation itself can take one to three weeks at Cornwall Council depending on workload, so plan for around three to four months from drawing start to decision.
- Do I need planning permission or is it permitted development?
- It depends on the property, the size and position of the works, and whether you are in a Conservation Area, AONB or Article 4 area. We'll review your address against the General Permitted Development Order at first consultation and tell you straight.
- What happens if planning is refused?
- We review the officer's reasons, advise honestly on the strength of an appeal, and where a redesign is the better route, prepare a revised scheme. The free re-submission window inside twelve months can be used strategically.
- Will you visit the site before designing?
- Always. Cornish sites have wind, light, slope and access quirks that don't show up on a Google Street View. A site visit is built into every fee proposal.
