There’s a tiny house storm brewing in Pittsburgh.

The story starts several years ago, when local urban planner and developer Eve Picker sought to revitalize Garfield, a low-income, predominately African-American neighborhood in the rapidly changing East End of the city. Picker, founder and CEO of non-profit think tank cityLAB, wanted to bring artists into the neighborhood in the hopes of attracting economic development. She called the project 6% Place.

Why? “Six percent is the number, the tipping point,” reads cityLAB’s website. “If a neighborhood can get that many creative workers, it becomes an attraction in its own right, according to a study by CEOs for Cities. cityLAB has been testing out this hypothesis in Garfield, an overlooked neighborhood in Pittsburgh’s East End, since 2011. Our goal is to fill in the neighborhood’s vacancies with creative workers who will be good neighbors, invest in the community, and help the neighborhood grow sustainably.”
