Mac Stopa designed the Warsaw Spire office complex developed by the Company Ghelamco with the Drum Collection displayed in several areas of the gallery. In Warsaw Spire the most important interior design elements such as ceilings, floor quartz tiles, prefabricated wall systems and carpets have a geometric modular appearance with an organic vibe. Drum and Warsaw Spire represent a perfect match. An Art Walk, 60 meters exhibition wall. This is a new type of art gallery where creative works of young artists are presented in illuminated organic windows.
