“AM INN” Office Building

LORENZATELIERS’ compact extension plan for the BORA sites in Niederndorf focuses on densifying already developed areas near the Inn and creating an efficient “company campus” by connecting existing buildings via bridges. This approach reduces land use and improves operational efficiency. The new building features five above-ground floors of office space, designed around a central core with communal facilities and two interlocking staircases. All offices are located along the outer facade for maximum workplace quality, aligning with modern office standards and offering potential for conversion into residential or hotel use.

A distinctive feature of the building is its cantilevered balconies that create informal work areas, expanding on the second floor to spacious, covered lounges with views of the Inn’s wetlands. The building’s dynamic exterior features a railing of variably twisted flat steel bars. The thermal envelope on the upper floors includes a post-and-beam construction with openable elements for balcony access, supplemented by sun protection. Sustainability is a key focus, with photovoltaic elements on the roof and a groundwater heat pump for climate control.
