In a follow-up to last fall's Designing Livable Communities Summit, the University of Minnesota is bringing in California architect Michael Pyatok (PEYE-uh-tahk) this weekend to talk about one of his affordable housing projects. Pyatok, a Fellow of the American Institute of Architects, designs high-quality low and moderate income housing that incorporates many suggestions from the residents who will actually live the homes he creates. Pyatok says government and non-profits must work together to find the land and funds to build affordable housing. But he says the affordable housing shortage won't be resolved until Americans change the way they think about housing in general.
