Granny Flat Designs
1 Bedroom Granny Flats

One bedroom granny flats are increasing in popularity. One bedroom designs are ideal for housing relatives or as a practical and versatile space for home studio or home office use.
2 Bedroom Granny Flats

Two bedroom granny flats make for the perfect floorplan striking a balance between amenity and space. Two bedroom designs are ideal for maximising returns on an investment property or extra room for the family.
3 Bedroom Granny Flats

Three bedroom granny flats share the advantages of a traditional house for a portion of the price. Great for AirBnB retreats, first time property investors, student accommodations and large families.
2 Storey Granny Flats

Two Storey granny flats are a popular choice for investors and families who have more land to work with. They provide extra flexibility and function in the amount of space that comes with having a lower level.
