This bilingual community toolkit aims to equip citizens with knowledge about building shells: uninhabitable buildings that lack floor plates and/or roofs due to fire, water damage, neglect, etc. This renegade typology ends up creating holes in the fabric of a vibrant city block.

The toolkit illuminates why people should care about this issue and the benefits to come from collective action. Action items for intervening in the trajectory of a building on the decline are organized into a matrix along axes of least effort ↔ most effort and city action ↔ community action.
