Self-contained living spaces adjacent to a main house are referred to by lots of different terms: dual occupancy homes granny flats, garden rooms, and most commonly, granny annexes. They are usually quick to build and provide a space that can be used as a solution for families with a variety of needs such as housing an elderly relative, teenagers or grown children with disabilities. 

Uses for dual occupancy homes 

Having a property with two living spaces is a great marketing opportunity and will appeal to a range of buyers. It isn’t just the elderly who use granny flats, first-time buyers can use them as a solution to rising housing and living costs. 

Annexes can also provide a practical solution for grown children with disabilities who can gain independence while still being close to parents. They can also work as guest suite or for the holiday rental market. 

You can also let out your annexe or use it as a holiday home, allowing you to have another stream of income.  

In Scotland, you need planning permission under the following circumstances:  

  • The structure is over 30m2 in size or takes up more than 50% of your garden area.  
  • It is erected within a conservation area or beside a listed building.  
  • It requires water and drainage for a kitchen or bathroom.
