The "Sugus" buildings, located a 10-minute walk from Zurich main station, are at the center of controversy as plans for a total refurbishment could double current rents of 105 apartments, which range from 1,000 to 2,300 francs. Manager Goran Zeindler and heiress Regina Bachmann are reportedly valuing the properties at 200 million francs, despite an investor's offer of 75 million. The situation has sparked protests, and both Zeindler and Bachmann have remained silent amid growing media attention.
