Planning rules that apply in Colwyn Bay
In Wales a glazed or orangery-style extension follows the normal single-storey limits (up to 4 m at the rear). Welsh building regulations also limit glazing and heat loss, so glass-heavy designs need calculations.
The planning position for a specific Colwyn Bay address depends on its history and any designations, which is why we check it at the first visit.
The Party Wall etc. Act 1996 applies in Wales as in England: notice must be served before work to a shared wall, building on the boundary, or excavating close to a neighbour's foundations.
Applications are decided by the local planning authority (your county or county borough council, or the national park authority).

Who an orangery extension suits
- Period and detached houses with a garden view
- Homeowners replacing an older conservatory
- Those who want daylight without overheating
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.

Orangery extension questions answered
How long does an orangery extension take to build in Colwyn Bay?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do I need building regulations approval in Colwyn Bay?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Colwyn Bay?
Yes. We cover Colwyn Bay and the surrounding parts of Clwyd. Site visits are free and there is no obligation.
How much does an orangery cost?
Our guide range is about £2,230 to £4,180 per m² including VAT, so a 16 m² standard-spec orangery is typically £41,500 to £52,500 in Colwyn Bay.
What is the difference between an orangery and a conservatory?
An orangery has a solid roof perimeter with a central lantern and more solid wall, so it is warmer and more like a room. A conservatory is mostly glass. Building regulations treat a heated orangery joined to the house as an extension.
