If you get a chance to walk on the Overblaak Street in Rotterdam, Netherlands. You could see these 32 cube houses all attached to each other. This set of innovative houses was designed by an architect by the name of Piet Blom in 1984. Each cube house has three floors. The reception, the kitchen and the living room are on the first floor. The bedroom and bathroom are on the second floor. The third floor is used sometimes as a small garden. I’m still amazed how people can live in these tiny houses.
