Upon first glance, the xbo housing unit resembles a transport container. It is a two-piece rectangular volume with a base area that measures 3.2 x 12 metres. These two sections can be pulled apart to a maximum length of 19 metres, with the help of a hand winch. When the two sections are pulled apart from each other, they form an inner outdoor area. This outdoor area can be open or closed, depending on the wishes of the resident, with the help of vertical Venetian blinds and hinged gates.
