In cooperation with Sud Architectes Polska, OJL Group realised the refurbishment, extension and modernisation of the Europejski Hotel in the central part of Warsaw.

The owner of this nineteenth-century building, which is considered an architectural pearl of Warsaw, planned to modernise the building and create a five-star hotel with restaurants and luxury boutiques on the ground floor. Another two floors, hosting class A offices, were added to the building. Moreover, the 4 underground levels will house a spa & fitness centre, car parks and technical rooms.

The investment was commissioned in 2017.
