Belgian developer Atenor Group on Tuesday inaugurated a €40 million office building in Budapest, the first unit of its “Váci Greens” complex. The 15,700sqm building is located on Vaci ut, one of the capital’s main thoroughfares. It was built with Atenor Group’s own resources, said CEO Olivier Ralet. One-quarter of the building’s space is being leased at present, but it is expected to fill up by autumn. The plot has space for three more buildings with a combined area of 80,000sqm. A 20,000sqm building could be constructed on an adjacent plot.
