One of the last things you'd expect to find on a large vacant lot in downtown Philadelphia might be an exhibition full of progressive thinking on sustainable design. But from now until October 30th, A Clean Break will be putting a previously empty space to good use by showcasing low waste innovations for the urban environment.

A Clean Break exhibit brings together the work of architects, furniture designers, product designers, artists, landscape designers, forward thinkers, and everyday design-minded activists to present a collection of work addressing the how of sustainability.
