3 Years ago today (with generous help from Dad and Mum) we had a garage built. Originally we intended to use our acquired building knowledge to build a strawbale garage, however parenthood does tend to take priority. So with my parents urging and financial assistance we decided to go with a steel frame garage with Colorbond cladding. Interestingly, Colorbond autocorrects to "collarbone". Please don't clad your garage with collarbones. That would be creepy.
Here's a video of the prep for the slab and the pour - https://youtu.be/eSzINsKuQT4
