As part of the revitalization of the St. Georg district in Hamburg, an ensemble of residential buildings and an administrative building has been created on a partial area of the St. Georg Hospital.

The clinic wings were continued by new apartment buildings. They enclose a spacious, noise-protected inner courtyard, which is equally available to the residents and the employees of the office centre.

The office building’s configuration, composed of four boomerang-shaped elements laid over each other, creates a representative entrance situation, an interior courtyard, and a transitional space to the residential courtyard in the rear. As a result of this building form, every office has direct sunlight and an unobstructed view.

The building is designed and constructed as a sustainable, resource-saving house. The structure is compressed and space-optimized. Two interior cores allow flexible use and easy adaptation to future usage requirements. The building materials are ecologically safe with Blue Angel certification. The primary energy demand is minimized by a highly thermally insulated outer shell, natural ventilation (double facade), the use of highly efficient building technology, low-energy heating and concrete core activation as well as an energy-optimized lighting concept.
