Home Offices: A dedicated workspace away from household distractions.

Workshops: For hobbies.
-
Summerhouses: Relaxation spaces for leisure and entertainment.

Garages: For vehicle storage and maintenance.

In the UK, many outbuildings fall under "permitted development" rights, meaning you don’t need formal planning permission if certain conditions are met:
-
Single Storey: Must be a single-storey structure.

Height Restrictions: The maximum height is 2.5 meters if within 2 meters of a boundary, and 4 meters with a dual-pitched roof.
-
No Sleeping Accommodation: Outbuildings cannot be used for sleeping.
-
Area Limits: Cannot cover more than half the area of land around the original house.
Residential Annexes
Creating a residential annex usually requires planning permission because it involves changes that affect the character and use of the property. Key considerations include:
-
Impact on Neighbours: Privacy, noise, and light considerations.
-
Design and Appearance: Should be in keeping with the main house.
-
Accessibility and Parking: Adequate parking and access must be provided.
