The Serenity Floorplan

The Serenity is a truly spacious one bedroom Portable Cabin that provides ample room for relaxation and comfortable living. The verandah extends the living area providing a perfect place for entertaining, enjoying your morning coffee or dining.

The open plan living and kitchen area is designed with both form and function in mind, featuring stylish cabinetry that provides plenty of extra storage space. The two-burner cook-top and continuous gas hot-water system are perfect for preparing meals and enjoying all the comforts of home, while the air conditioning ensures that the cabin stays cool and comfortable even on the hottest of days, and warm and cosy throughout the cooler seasons.

Our Quality

At PennyGranny™ our transportable homes are either built by us or bought in bulk from most reputable Australian manufacturers built to our specification. As a hire company we need to make sure that our buildings used in our hire fleet are built to last many years and can withstand harsh Australian conditions. When you buy a portable home built by a third party supplier, you can be sure that we’ve done all the hard work of only choosing the Australian suppliers that deliver a high quality product. All of the portable homes offered for sale are brand new, same homes that would otherwise be used in our hire fleet, and due to our buying power brought to you at competitive prices.
