This week on Smart City: Public space is important in both cities and in buildings. We'll talk to two people who are attempting to re-imagine those public spaces both inside and out. Antony Wood is the Executive Director of the Council on Tall Buildings and Urban Habitat. He studies and reports on all aspects of the planning, design and construction of tall buildings. He'll tell us about the revolution that is needed in tall buildings to transform them into livable structures for the 21st century.

And we'll speak with David Dixon. David is the principal of Planning and Urban Design with Goody Clancy and Associates and we'll talk about his amazing urban design work in Miami, and what he learned about Muslim principles of design when he took his ideas to Pakistan for a project in Karachi.
