Clacton-on-Sea orangery extensions, designed and built
A orangery extension in Clacton-on-Sea starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Do I need planning permission in Clacton-on-Sea?
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).
Working in Clacton-on-Sea
We cover Clacton-on-Sea and the postcode districts CO15, CO16. We also work in nearby Harwich (12 miles), Colchester (13 miles), Maldon (21 miles), Witham (22 miles).
Just over the Suffolk border, Felixstowe is about 15 miles away. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Included in a typical project
- Design of piers, roof perimeter and lantern proportions
- Heating sized for the glass area
- Opening into the main house
- Foundations, walls and insulated perimeter roof
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.

Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.

Build and sign-off
Our team builds the extension, keeps you updated weekly and finishes with building control sign-off.
Your questions about an orangery extension in Clacton-on-Sea
How long does an orangery extension take to build in Clacton-on-Sea?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do you cover all of Clacton-on-Sea?
Yes. We cover Clacton-on-Sea and the surrounding parts of Essex. Site visits are free and there is no obligation.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Clacton-on-Sea, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Does an orangery need planning permission?
It follows the same size limits as other single-storey extensions. In England many fit within permitted development or prior approval; others need an application.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.
