Do I need planning permission for an extension in Carbis Bay?
The honest answer is that it depends on your specific address, and that is not evasion. Permitted development rights are set nationally but they are removed or narrowed in particular circumstances, and Carbis Bay has its share of them: the AONB designation, listed buildings and their curtilage, flats and maisonettes, and estates where an original planning condition removed the rights outright. We prepare and submit planning applications to Cornwall Council and, where relevant, the Isles of Scilly authority — handling drawings, statements, validation queries and officer negotiation from start to determination. A Carbis Bay brief starts on the street, not the screen — Carbis Bay is the residential coastal suburb of St Ives, climbing up the cliffs above one of the calmest beaches on the north coast and built largely between 1900 and 1970, with a building stock that leans toward post-war bungalows and modern coastal architect-designed homes.
Carbis Bay sits in West Cornwall — just off the A3074; with Truro the closest city; 1 miles from St Ives.

Why Carbis Bay is its own job.
Around Carbis Bay (TR26), aONB designation covers the whole village; coastal views and cumulative cliffside development are weighed in most applications. Carbis Bay sits inside St Ives parish's principal residence policy area. For planning application 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 Carbis Bay drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Reading Carbis Bay properly up front saves more time than any drawing tool ever will. Most of our planning application work in Carbis Bay lands on post-war bungalows, with detailing that has to nod to the wider Lelant streetscape. Salt air and prevailing wind change specification long before they change planning. We tend to draw weathering details in full, then check whether coastal or AONB policy narrows the design options for this address.
Planning note
Cornwall Council's planning team is among the busiest in the South West. A clean, well-documented submission moves through validation faster than a bare-minimum one.
What we focus on
Planning considerations specific to Carbis Bay.
01
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
02
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
03
Cornwall has more than thirty Conservation Areas and large stretches of AONB; planning weight on materials, mass and form is significantly higher in those zones.
04
Tree Preservation Orders, ecology surveys and neighbour consultation responses can change the validation list mid-application.

Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Who this is for

- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Sites we know on the ground here include the area around the beach and Carbis Bay Hotel.
- Drawings, planning and building regulations are all produced in-house, so a planning application enquiry does not get passed between firms.

Our process
How a Carbis Bay planning application project runs.
Step 1
Initial review
We assess constraints — Conservation Area, AONB, listed status, Article 4, TPOs, flood zone.
Step 2
Strategy
We recommend the right application type and likely fee, programme and supporting documents.
Step 3
Drawing and statement preparation
Plans, elevations, sections, block and location plans, plus DAS and any heritage or ecology input.
Step 4
Submission and validation
We upload to the Planning Portal, pay the council fee on your behalf and respond to validation requests.
Step 5
Determination
We monitor consultation, respond to officer queries and negotiate amendments where it improves the chances of approval.
Householder applications are typically eight to twelve weeks from validation; full planning runs thirteen to sixteen weeks; major or contentious schemes can take longer.

Local fabric
What sets a Carbis Bay planning application brief apart.
Building stock
Across Carbis Bay (TR26) we work on Edwardian and 1930s detached villas, post-war bungalows, 1960s estate housing, modern coastal architect-designed homes. Each stock type drives a different planning application response — post-war bungalows in particular needs careful detailing here.
Parish & policy
Carbis Bay sits in the parish of St Ives, which matters for how parish-level consultation lands on a planning application application.
Coverage
We cover TR26 from our studio, with regular planning application jobs also running in St Ives. Most Carbis Bay site visits get booked within the same week.
Do you work in Carbis Bay regularly?

Carbis Bay Planning — local questions answered.
- What is permitted development?
- A set of nationally granted rights allowing certain works without a planning application, subject to size, height, position and material conditions. It is not a blanket permission, and it does not apply to every property.
- How do I know if my Carbis Bay property has permitted development rights?
- Check whether the property is listed, whether it sits in a designated area, and whether the original permission carried a condition removing the rights. Cornwall Council holds that record and the Planning Portal explains the national rules.
- What is a lawful development certificate?
- A formal confirmation from the council that your proposal is lawful without planning permission. It is optional, but it protects you at resale and mortgage lenders and solicitors often ask for it.
- Does permitted development mean I can skip building regulations?
- No. They are entirely separate. A permitted development extension still has to comply with building regulations and be signed off.
- Do I need to consult my neighbours before applying?
- You don't have to — the council formally consults them — but a quiet conversation early on usually pays off. Objections from neighbours are weighed by the planning officer and can be the deciding factor on borderline schemes. In Carbis Bay specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- What's the difference between full planning and householder?
- Householder covers extensions, outbuildings and alterations to a single dwelling. Full planning is needed for new dwellings, change of use, and anything affecting curtilage subdivision. We'll confirm which route fits at first review.
- What if the council asks for more information after submission?
- Common, and usually fixable. Validation requests, ecology comments, highways queries and design tweaks all get handled by us inside the application — no extra fee unless the scope changes substantially.
