I know they are busy
Lots and lots. Gave up work (yay!) so I can make meetings with builders during the day
Actually you might be interested in the company I met today. Thompsons Sustainable who have just opened a branch in WA. It's framed construction (like eastern states) but build times are around 16 weeks.
Besides my own 6 projects I'm doing site finding and feasibility for others and some mentoring for those who want to learn or have a second opinion on their own developments.
