The 4 common Granny Flat Facades. Which is best suited to your need?

The External Facade  is a non-loadbearing skin or layer attached to the outside of a Granny Flat to protect the building from the effects of weather and water. It is mainly responsible for the the aesthetic appeal of the Granny Flat and directly influences both building cost and property value.

Your choice of Granny Flat facade will have a significant effect on the environmental performance of your Granny Flat.
