Home Plus One is your local team of specialists for designing and building granny flats. We provide a stylish addition to your property in the Blue Mountains.


The Perfect Home Extension

Blue Mountains homeowners are increasingly choosing to build granny flats on their property to expand living space and add value to their homes. The concept is very popular as a granny flat gives you the freedom to use additional space however you’d like, and it doesn’t involve the invasive construction of a traditional home extension.

Self-employed workers can use the space to achieve a separation between work and living areas; extra bedrooms can accommodate teenage or elderly family members who want to be a part of the home but maintain independence. The additional space is also a guaranteed way to increase the value of your property.
