About real estate

We offer you exclusive timeless offices in a new commercial project in Karlín. This is a working environment of exceptional quality and design. For tenants, there are bright offices of a unique character with opening windows, allowing the division of space, whether it is a type of open-space or separate units. A quality working environment is created by the clever combination and implementation of all key elements, cutting edge technology, impeccable design and quality construction. It is a modern building offering a total of 16,710 m² of top quality lettable office space.


The project has many advantages, but its location is one of the biggest. Its proximity to the city centre (just 2 subway stops or 5 minutes by car) and its genius locci, reminiscent of SoHo in New York, make this a truly sought-after modern location. It's a vibrant place, but away from the hustle and bustle of the city centre.
