Homes in Gwynedd and Anglesey
Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.
What do you get with 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
- Planning or permitted development check
- Insulated roof perimeter with plastered pelmet
