Fresh, Innovative Granny Flat And Portable Building Designs Direct From The Manufacturer

Whether you need a granny flat, more room for storage, a teenager’s or parents’ retreat, portable sleeping quarters that sleep six people or more, a site office or lunch room, or something a little out of the ordinary… Whatever your need, Portable Buildings International has a portable building solution for you. You can pick from our standard designs and floor plans, or we can customise your portable building to meet your exact needs.

Every portable building or granny flat we manufacture is built on a super strong steel beam base using high tensile steel framing for extra strength. This makes it much safer in wild weather, increases the lifespan and value of your portable building and prevents any termite issues.

Dealing direct with the manufacturer gets you the best price, the best service and the best advice!

Did you know that buying a granny flat or portable building is a fraction of the cost of a traditional home or renovation?

Putting a granny flat or portable building on your residential property adds value to your existing property. As a business, you can reduce your outgoings by purchasing your own portable building – It makes good business sense!

All our steel framed portables are manufactured to meet and exceed Australian Standards by our highly experienced tradesmen in our Design, Manufacture & Production facility.

Apart from solving your space, sleeping or storage problems, all Portable Buildings International structures come with:

  • “Delivered In Perfect Condition” Guarantee
  • 10-Year Structural Guarantee
  • 25-Year Guarantee against rotting

Do you have sore eyes and a headache from trying to work out your best portable building option? New or second hand? Larger or smaller? Maybe you want to design your own?
