P15 is a small residential penthouse functioning as an office on the busy Prenzlauer Allee, featuring a terrace and a 360-degree panoramic view over Berlin. The client wanted to rent the space as an office, with the option to convert it into two separate apartments, if needed. The introduction of an elevator was also part of the renovation which required access bridges from each floor on the courtyard elevation. I was part of the project team from the schematic design phase up until and including the construction documentation.
