Last week, we had a special sneak preview of the Center for the Urban Enviornment‘s cool new Gowanus headquarters. The public grand opening takes place on Saturday, May 10 from 11:30AM-4PM. Per an email:

The Center for the Urban Environment opens the doors to its new green building with hands-on fun for the entire family. Participants can tour their amazingly green facility, create green building models, view a neighborhood puppet theatre, join a walking tour of the Gowanus, hear live music from blue grass funk band “Astrograss” and watch a special screening of Twilight Becomes Night. Bring all items to recycle: CDs, pagers, PDAs, plastics, clothes, cell phones and the like and find out how you can be a part of Brooklyn’s green movement.

The location is 168 7th Street, which is between Second and Third Avenues.
