Covering Motherwell
We work in Motherwell (ML1) and the places around it, including Hamilton, Wishaw and Coatbridge.
Homes in Lanarkshire
In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.
What is a garden annexe?
A garden annexe is a separate single-storey building in the grounds of a house with its own bedroom, bathroom and kitchenette, used by family members as part of the main household. Unlike a garden office, an annexe that people sleep in normally needs planning permission and full building regulations approval.
- Foundations and drainage connections
- Heating, hot water and electrics
- Accessible design options for older relatives
What will a garden annexe cost?

|---|---|
| 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 |
Planning and building rules in Motherwell
Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.
In Scotland an annexe needs planning permission and a building warrant before work starts.
What can change the price or programme?
- The annexe normally has to remain part of the main household, not let as a separate home.
- Council tax treatment depends on who lives there; check with your council.
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.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Garden annexes: common questions
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.
Can you make it wheelchair accessible?
Yes. Level access, wider doors and a level-access shower can be designed in from the start.
How do I get a price for garden annexes in Motherwell?
Use the guide price tool for a ballpark figure, then book a visit for a fixed written price for the agreed specification.
