Homes in Gwent
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 a garden annexe?
We design annexes as permanent buildings with proper foundations, insulation and services, and we prepare the planning case showing how the annexe will be used as part of the main home. Connections for water, drainage and power are planned from the start.
- Planning and building regulations checks under Welsh rules
- Design and planning application
- Foundations and drainage connections

Do you need permission for a garden annexe in Chepstow?
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.
In Wales an annexe with sleeping accommodation needs planning permission, usually with a condition tying it to the main house.
What should I think about before starting?
- The annexe normally has to remain part of the main household, not let as a separate home.
- Drainage may need a pump if the garden falls away from the sewer.
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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
