The project comprises the remodelling, renovation and modernisation of a 4^1/2-room Wilhelminian style apartment in Berlin Charlottenburg. Tailored to the individual needs of the clients, the original floor plan is restructured including the optimisation of the so-called ‘Berliner Zimmer‘, wich is often a spatially unsatisfactory and dark area between the front building and side wing, as well as reducing the previously 16m long corridor to a minimised length of 5m. The result is a spacious central room featuring a bespoke freestanding piece of timber furniture which serves as kitchen island on one side and wardrobe on the other side separating the entrance lobby from the kitchen cum living room. The bathroom, previously located right next to the entrance, is relocated close to the bedrooms within the more private area of the apartment in ​​the side wing. Another built-in furniture unit with an integrated bath tub serves as a two sided closet and separates bathroom and guest/study room. The newly created spacious centre with its linking position efficiently connects the more representative area of the apartment with the two living rooms at the front with the more private part with bathroom and the two bedrooms in the rear. The open and floating floor plan enables diagonal views throughout the apartment and links the internal with the outside spaces, creating a more generous, bright and modern atmosphere. The built-in furniture as micro-architecture pieces follow a structural and tectonic concept of horizontally and vertically inclined surfaces. The resulting ornamental shadow patterns emphasise the three-dimensionality of the furniture family, which is complemented by additional elements such as sideboard, kitchen table and bedroom cupboard in varying colours.
