We should have art, both permanent and temporary, outside as well as inside. Art can help make it a city hall inclusive of all of the people of Seattle. Include all citizens. Some are polite and some are not - the Civic Center should include all. The plaza should be lively, informal, warm, inviting.
Precise geometry can be off putting but can be made to work.
In the design the plaza access looks very limited. Plaza success depends on good understanding of how space is ordered and how people structure space. The building should be a place for the expression of community. The Civic Center can be an anchor of celebratory events through out the year. These can introduce people to Seattle, the communities of Seattle, as well as the Civic Plaza and the City Hall.
