Building business

This week I will be on a hunt for designers who are practicing a design entreprenerialship. I came across the work of Charlotte Sken -Catling via a post on remodelista about a residential project. On her web site she shows this project Eco-lab in which she was the director and visionary behind the project. It seems to be a health and wellness emporium along with a cafe. I know why I came to design project for myself in their entirety but why do others? Its an interesting point in time for designers with the economy and does that mean we may be our only client?
