Diamentum Office has acquired two new tenants-Gigaset Communications Poland, a European leader in DECT phones, and Pattonair Poland, a company that supplies the aerospace and defense industry. Both companies lease nearly 3,000 square meters of Class A office space. The commercialization level of the office building is 80 percent, which illustrates its remarkable attractiveness. Next to the seven-story Diamentum Office is the Carbon Tower development, offering 19,000 square meters of space, to be completed in the fourth quarter of 2018.
