Installing hammock in a certain park might be a problem since the area provided for this purpose is limited. Several architects work on a solution that allows its citizen to enjoy plenty of hammocks without consuming too much park areas. The solution for this problem is a four-story building that can be used to hang hammocks. Each floor can be used to hang six hammocks in three sections. With attic area included, it can accommodate up to 30 hammocks at the same time. Front and back walls are replaced with railings. Therefore, its occupants are able to enjoy the evening air from safe place.
