How much does a Kubby cost?

It depends on the size and the package. Kits start from $20,000 + GST, Lock-up from $34,000 + GST and Turnkey from $60,000 + GST. Every design page lists the guide price for each size. Send us your property address and we'll prepare a free, site-specific proposal with your final price.

What's the difference between Kit, Lock-up and Turnkey?

A Kit is everything you need to build your Kubby, delivered to your site, for you or your own builder to put together. Lock-up adds construction on site, so it's built and weather-tight, ready for you to finish inside. Turnkey is the complete package: approvals, construction, bathroom, electrical and plumbing, ready to move in.

What can I use a Kubby for?

A Kubby can be a granny flat, guest room, home office, studio, games room, home gym, kids' playroom, pool house or rental. Most people end up using theirs for more than one thing over the years.
