Room Extensions Perth

The Granny Flats Warehouse can design and build a new room for your existing home, providing a true addition to your living space. Designed as a stud frame unit, with stylish finishes inside and out, these room extensions are constructed to blend seamlessly with your home.

All room units have a concrete floor, steel stud frame and are Gyprock lined with a range of Weathertex external cladding. They come complete with internal ceilings, cornice mouldings and aluminium sliding door and windows. These are not prefabricated transportable units but totally built on site by our tradesman from individual materials.

The design style of our room extensions means that construction time is reduced compared to the more traditional use of bulky frames, bricks and tiles.

The Granny Flats Warehouse provides quality room additions and building extensions that are a stylish and affordable solution for your home.
