Introducing 10 Brand New Granny Flat Designs Each With 5 Stunning Facades

Each designed to meet new BASIX requirements as at 1st October 2023.

Downsize in your own backyard.

Eddie wanted to build a place for his daughter who had just finished her studies at university. He and his wife were worried about how difficult and expensive it was for young people to get a place to live these days. Observing that they had plenty of space in the backyard they decided to build a Granny Flat. They plan to live in the Granny Flat later on when their daughter has bought her own place.

They see multiple benefits of living in the Granny Flat later in life including having a 'home base' while they travel, and also being able to rent out the main home and supplment their retirement income.
