We redesigned something you can find in every big city: mobile billboards. And turned them into a shelter for the homeless, one that finances itself with the ads on its roof. The City Life Billboard. On its façade, a sign welcomes users, asking them to come in. A lockable door leads them inside, where there’s room for a homeless person and their dog. Outside on the billboards, we call on all citizens to help end homelessness by 2030, at the latest. #ZeroBy2030
