Cologne – November 03, 2026 -- COLLECTION Business Center in the Wallarkaden at Rudolfplatz 3 lets companies hold a Cologne business address without leasing a permanent office, separating the question of where a firm is present from how much floor space it needs.

Fifth-floor center combines address, phone service and bookable rooms

The center occupies the 5th floor of the Wallarkaden, in Cologne's inner city. Eric Kuster Metropolitan Living designed the interiors. Reception, personal support and roof terraces complement the work and meeting areas.
