Interstitial Space

Abstract: In certain types of complex historical buildings an in-between space was often present. This space was a consequence of something more important such as another room, a necessary movement or the thickness of the wall. This thesis aims to investigate this kind of space, mellanrum, on an interior and urban scale. The case studies are Stockholm slott, Rosersbergs slott and Gripsholms slott, the rooms are documented in plan and with a portrait. The small island Riddarholmen is one of the oldest parts of Stockholm, mellanrum is here investigated on an urban scale, mainly in model. Most of the houses on Riddarholmen are owned by the Swedish state and are housing different courts, they need more space but extensions to the old houses are hard to do so a way of freeing space is to collect all the libraries on the island (five in total) in one common court library. In the design of this small institution mellanrum is investigated further and incorporated in a new building. of wood.
