At its narrow end, the elongated building site in the outer Seefeld district stretches from the lakeside promenade to the Weinegg neighbourhood, while also being framed by the commuter railway lines and the street space around Bellerivestrasse and Seestrasse. The two longitudinal ends of the plot are defined by the preservation-listed Tiefen­brunnen station, which was constructed in 1892, and a car-wash facility. The proposed landmark would create a fixed point on the boundary between Zurich and Zollikon.
 
The architectural language of this 135-metre long commercial development refers to the buildings along Bellerivestrasse by Jakob Zweifel and Franz Füeg. The new building asserts itself in the tradition of these post-war commercial headquarters: the proposed finely structured, urban volume has a vertical structure inspired by the classic development of an extra-high basement level, a central section and an extra-tall attic level designed as a crowning structure. A head-end structure is developed by compressing the attic, which is followed in its longitudinal development by an incision beneath the permitted building height of the standard floor. This head-end structure combines with the existing station building to shape the new urban station square. 
 
The new commercial building integrates public underground Park & Ride facilities, as well as parts of the car-wash facility. Sales areas are provided on the ground floor. The attic level accommodates a restaurant with a broad view of the lake. 
 
Two acentric cores structure the open floors, which are borne by concrete lumbar sup­ports. A glass building envelope with a grid of 1.5 metres affords views through and into the volume, and is surrounded by irregular, playfully positioned vertical façade pilasters made of anodised aluminium.
