Possibly, but this often requires planning permission and must comply with height and design considerations.

Can I build an outbuilding in my garden?

Outbuildings may be permitted development if they meet height, location, and usage restrictions.

What is prior approval neighbour consultation?

For larger extensions, councils notify neighbours and assess specific impacts before granting prior approval.

How close can I build to my neighbour’s boundary?
