The eight-storey KEYSTONE building meets all the requirements for modern office space. The choice of materials, precision of workmanship, architectural details of common areas and design reception make the building one of the highest-quality projects of recent times. In addition to offices, it also offers 850 m2 of commercial space and parking spaces on 3 underground floors. Built in 2012, Keystone was one of the first office buildings on Rohanské nábřeží and heralded the major development of this sought-after location. It was designed by architects Mathias Müller and Daniel Niggli of the Swiss architecture firm EM2N. It impresses especially with its spectacular double façade and green garden on the roof terrace.

Thanks to its location on the corner of Pobřežní and Šaldova Street, Keystone forms a kind of gateway to Karlín. The building is easily accessible by car and public transport (tram and metro stops are within walking distance - Křižíkova).
