Not a long time ago the site where the modern Q22 155-metre office building is to be developed soon included the building of the former Mercure hotel.

The investor started the construction process with a demolition of the abandoned building. All the materials collected in the course of the demolition have been recycled, which provided 1,500 tonnes of steel and 25,000 tonnes of concrete aggregate. The steel and the aggregate have been used for the construction of other Warsaw projects of Echo Investment.
