What goes into 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.

Foundations and drainage connections
Brick, block or timber-frame structure
Heating, hot water and electrics

What will a garden annexe cost?

Typical ranges for garden annexes. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Garden annexes	Guide price incl. VAT
Standard specification	£2,400 to £2,900 per m²
Good specification	£2,900 to £3,400 per m²
High specification	£3,400 to £3,900 per m²

How is a garden annexe approved in Gwent?

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 can change the price or programme?

Drainage may need a pump if the garden falls away from the sewer.
A level threshold and wider doors make the annexe suitable for later life.

How does the project run?

Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

What people ask before starting

Can I rent the annexe out?

Usually not without a separate planning permission, because councils normally require it to stay part of the main house.

How long does an annexe take to build?

About 14 to 24 weeks on site after approvals.

Can you visit a house in Gwent 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.
