Homes in Gwynedd and Anglesey
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What is an orangery?
An orangery is a single-storey extension with brick piers or walls, large windows and a glazed lantern set into a solid, insulated roof. It sits between a conservatory and a full extension: lighter than an extension, warmer and more solid than a conservatory.
- Planning and building regulations checks under Welsh rules
- Foundations, brick piers and insulated base
- Insulated roof perimeter with plastered pelmet

Planning and building rules in Gwynedd and Anglesey
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Wales has its own permitted development rules, set by the Welsh Government. Small single-storey rear extensions can often go ahead without an application, but the limits differ from England's and there is no larger-extension prior approval route, so we check the current Welsh rules for your house before drawings are finalised.
What can change the price or programme?
- Timber-look aluminium or timber frames suit period houses.
- Solar-control glass in the lantern stops summer overheating.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Your questions answered
Does an orangery need building regulations?
Usually yes, because it is built as part of the house rather than as a separated conservatory.
Can it be used in winter?
Yes. It is insulated and heated like any other room.
Can you visit a house in Gwynedd and Anglesey to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
