GBI AG  - The Property Developer

For GBI AG, “Temporary Living” is more than just one line of business among others: We work on that subject continuously. Classic Business, Design, Economy and Budget properties are firm parts of our portfolio as are mixed-use projects and our SMARTments product series. They all serve the increasing demand for sophisticated, temporary housing among different target groups.

In addition to developing the projects, the successful placing of the properties on the market is of special concern to us. That is why we bring together outstanding locations, dedicated operators and reliable investors. With our hotels, the first German fund for budget hotels could be launched. Our SMARTments were the first student apartments that were marketed institutionally, and this policy is continued successfully. We also sell apartments into part-ownership. We advise international partners and accompany them on their market entry in Germany. Our expertise is likewise in demand for external consulting mandates, lectureships and numerous presentations.
