I started to work online with students when, in 2015, someone from my daughter’s high school wanted to learn about co-housing but at the time I was out of the country. I had been teaching at her high school previously, working with a history teacher going through the periods from Mesopotamia through Egypt and to Rome, discussing how the social and political aspects of life affect how buildings are designed and what buildings are important to people in each time-frame. The online class on co-housing worked out well for both of us and the demand increased over time. Now I offer online classes on a regular basis.
