Text description provided by the architects. A farmhouse in the Mark Brandenburg, half an hour north of Berlin, was to become the client's new home and workplace. The agricultural use of the house was probably abandoned in the 1950s and the stable and workshop rooms were converted into four flats. The client decided to keep the remaining old tenant in the house and not alter this flat. The remaining areas were carefully remodeled and converted into living and working spaces by Christoph Wagner architects with Wenke Schladitz and reoriented towards the surrounding garden. A flat with 140 square meters was created on two floors. It was important to the client and the architects to preserve the character of the house with its traces and layers of time. A complete renovation was not desired. For example, cracks were only repaired where structurally necessary and not for design reasons. Large areas of the building were left untouched.
The formerly windowless gable wall now lets the morning sun into the house through a large, off-center round window. The curved brass window plate was shaped in such a way that it elegantly directs the water away from the wood and reflects the light deep into the house. The glass pane does not sit in a separate frame, but the cross-laminated timber (CLT) of the bay window was milled so that the pane could be inserted directly. The round glazing bead was made from brass by a befriended blacksmith and emphasized the special nature of the location. The largest structural intervention in the existing building was the opening in the south façade for the wide terrace window, combined with the ceiling opening for the staircase. The double-shell spandrel masonry of the outer wall is supported above the new window by an externally positioned balcony projection. This made it possible to avoid supports on the inside.
The new staircase marks the privacy of the upper floor with the side stringer of the upper flight of stairs raised as a privacy screen. This projects into the room from above as a negative form and meets the volume of the two lower flights of stairs at the landing. Demolition bricks were reused as non-load-bearing interior walls. The floor structure of glass gravel and regional hemp clay fill does not require any waterproofing membranes. Parquet floors demolished elsewhere could be partially reinstalled.
Christoph Wagner Architects has often experienced that building owners openly or covertly harbor the wish that an old house should be as comfortable as a new building and ideally be renovated in one go. They consider this to be wrong, and not just for reasons of sustainability. CWA believes that you have to know and understand a house to be able to react appropriately to its character by remodeling and extending it. This is usually a long process. The house in Lanke has now reached an intermediate stage. It is not finished. Just as architecture is never finished anyway and continues to evolve with its users.
