About us

In 1985, Christoph Ingenhoven founded ingenhoven architects, a practice that is one of the pioneers of sustainable architecture. The team consists of about 100 members of staff of different disciplines and aims to create architecture that responds to each respective location in a specific way and, at the same time, tries to find architectural answers to urgent questions of the present and near future. ingenhoven architects has won numerous competitions and awards. Using the term supergreen®, the practice pursues a comprehensive sustainability concept. It develops and builds projects of any size and typology in almost all parts of the world—all in accordance with the highest green building standards, such as those of LEED, Green Star (Australia), BREEAM (GB), DGNB (Germany), and CASBEE (Japan).

Christoph Ingenhoven was born in 1960 and studied architecture and art history at Aachen Technical University and, under Hans Hollein, at Düsseldorf Arts Academy. He is a founder member of the German Sustainable Building Council (DGNB) and the Federal Foundation for Building Culture. In addition, he is a member of the North Rhine-Westphalia Academy of Sciences and Arts.

The most important projects by ingenhoven architects include the Lufthansa HQ at Frankfurt Airport, the European Investment Bank in Luxembourg, the HQ of the Daniel Swarovski Corporation at Lake Zurich, the Lanserhof health resort at Lake Tegernsee, and the high-rise complex Marina One in Singapore. The high-rise RWE building in Essen was completed as early as 1997. It is one of the world’s first high-rise buildings with a double-skin facade for natural ventilation of the office spaces. In the same year, the design for Stuttgart’s main railway station was awarded 1st prize in an international architecture competition. In 2006 Christoph Ingenhoven received the Global Holcim Gold award—one of the world’s most valuable architectural awards—for the project, which is scheduled for completion in 2021.

One of the practice’s core competences is the design and implementation of highrise buildings. In 2012, ingenhoven architects was awarded the International High-Rise Building prize for the 139 meter high building 1 Bligh Street in Sydney, which was also certified with the highest Australian green building rating, “Green Star, six star”.

At the beginning of 2017, the foundation 123 stone for the Toranomon Hills project in Tokyo was laid, a 185-meter high office tower and a 220-meter high residential tower. The buildings are scheduled for completion in 2019 and, following the Breezé Tower in Osaka (2005–2008), are the practice’s second high-rise building project in Japan.

The hitherto largest project by ingenhoven architects is Marina One in Singapore—a 400,000 square meters high-rise project with two office towers and two residential towers that enclose a large public garden. The development will provide accommodation and workplaces for 20,000 people. The project, which has been completed in 2017, is an outstanding and groundbreaking example of a building in a megacity.

The head office of ingenhoven architects is located in the Düsseldorf Media Harbor precinct. In addition, the firm is represented internationally at St. Moritz, Sydney, Singapore, and Santa Clara in California, USA.
