The upper floors and rooftop of the Theresienhof offer 5,400 square meters of office space, configurable into two or three separate units per floor, depending on the layout. These flexible floor plans support a variety of furnishing styles, allowing the creation of tailored spaces for individual, group, or open-plan offices based on tenant preferences. Central access to all offices is through a natural stone-clad foyer on Theresienstrasse. A strategically placed stairwell, featuring two elevators and essential ancillary rooms, serves to connect the front building and the garden house. A distinctive feature of Theresienhof is its integration of landscaped outdoor areas across four levels on the courtyard side, enhancing the building’s structure. The design incorporates a selection of native plants and trees, natural materials, and the tranquil setting of the inner courtyard, crafting serene oases in both courtyards and on the roof terraces. Additionally, the garden courtyards are accessible from the ground-floor commercial spaces, offering significant added value, especially for restaurants.

The goal was not merely to fill a gap with the new construction but also to seamlessly integrate old and new elements. The building’s perforated facade, crafted from sand-colored natural stone, echoes the distinctive architectural features of the neighborhood. Above the first and fourth floors, a finely profiled horizontal cornice aligns with the neighboring building’s structure, creating the illusion of a continuous base despite the staggered floors. The window reveals are recessed into the natural stone, and the sills extend slightly outward, adding subtle depth to the building’s envelope. Throughout, wooden window profiles enhance the facade’s premium material quality. The facade design extends to the ground floor, where the shopfront windows reach down to the pavement in front of the retail and café spaces, ensuring a cohesive look with the entrances. The main entrance, offset and recessed diagonally across two window axes, is a discreet yet welcoming feature that blends smoothly with the facade. Similarly, the entrance to the underground parking is subtly incorporated into the building’s uniform grid facade, maintaining aesthetic continuity.
