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.
