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 section of the St. Georg hospital site. This project is named LTD_1 Hamburg and represents an important contribution to sustainable urban development. Moreover, LTD_1 combines modern architecture with urban quality of life. Consequently, the ensemble creates attractive living and working spaces in a central location that are convincing both functionally and aesthetically.

The hospital wings were extended by new residential buildings. These buildings surround a spacious, noise-protected courtyard that is equally available to both residents and the employees of the office center. Thus, a quiet, sheltered area is created, which promotes the well-being of all users. Additionally, this courtyard supports social interaction and offers a pleasant retreat in the middle of the city. As a result, the LTD_1 project significantly contributes to quality of life and a sense of community.

The centerpiece of the development is the new office building. The special design, consisting of four boomerang-shaped building sections, creates a representative entrance area, an attractive courtyard, and a direct pathway to the green residential courtyard at the back. Furthermore, all offices benefit from direct sunlight and an unobstructed wide view. Thus, the office building in the LTD_1 project combines functionality with high-quality design and modern working conditions.

The building was planned and constructed as a sustainable, resource-efficient house. The compact building structure is optimized for space, while two inner cores allow flexible use. In addition, all building materials are ecologically safe and certified with the Blue Angel label. Finally, a highly insulated exterior shell combined with natural ventilation, efficient building technology, low-energy heating, concrete core activation, and an energy-optimized lighting concept significantly reduce the primary energy demand and sustainably support the project’s ambitious sustainability goals.
