A polished port-holed façade gives little indication of the eco-ideology behind the Hotel Topazz, Vienna’s latest upscale hotel arrival. The architecture and interior design is by Vienna-based Michael Manzenreiter and pays homage to Viennese art luminaries Moser and Dagobert Peche, and owner Martin Lenikus. The exterior meanwhile is by Viennese firm BWM Architekten & Partner, known for their extension to the Folklore museum in Graz and their restoration of the Otto Wagner Pavilion. Topazz seamlessly blends into the historic first District of the city and takes to the podium as Vienna’s greenest hotel, with everything from construction materials to the bed linen locally sourced. Lying at the heart of the hotel is an intimate Salon where Lenikus’ own eco-friendly wine is served and guests are encouraged to converse, read and share ideas in the space, updating the salon etiquette at the turn of the 20th century.
