Feelings of homeliness are built on a variety of good relations, such as to the surrounding society, with your family members and the place called home. However, not all buildings are constructed to facilitate good relations for all as individuals have different needs in relationships. In a city district framed as a role model for social sustainability and an inspiration for building designs, shared spaces in wintergardens, large glass windows in homes, laundry rooms and recycling rooms invite some relations, while excluding others. In this paper we will focus on how glass as a building material affect the relations between residents, everyday practices, the neighborhood and the built environment. The increasing use of glass in architecture is an outcome of a reach into the building design from a range of different factors, such as architectural trends, safety measures and social sustainability efforts. Exploring glass through the concept topological reach (Allen, 2016) will make the ontological politics embedded in the building designs visible and in turn show what relations are made possible.
