Austrian architects BWM Architekten und Partner and Michael Manzenreiter have completed a hotel in central Vienna with big oval windows all over its brown mosaic facade.

Behind the glass, the windows are lined with cushions so that they can be used as sofas by guests.

Named Hotel Topazz, the skinny 10-storey building butts up against a neighbouring building and is located just a few streets away from St. Stephens Cathedral.

Other hotels we've featured include one that looks like children’s game Connect Four and one behind the facade of a derelict pub.

Hotel Topazz by BWM Architekten und Partner, Vienna

The new Topazz design hotel by BWM Architekten und Partner in Vienna’s city centre can be likened to a glistening, dark-coloured gemstone. Its brown mosaic façade, which absorbs and reflects the natural light, ensures that this building – on one of Vienna’s smallest building sites – is a real eye-catcher. The design, created by BWM Architekten und Partner, is characterised by striking elliptical window openings that jut out slightly.

This unconventional, distinctive treatment of the façade gives this round-cornered building a sense of weightlessness and elegance as well as an unusually physical presence within the fabric of Vienna’s historical architecture. Inside, the curved window recesses serve as comfortably rounded spots for sitting or lounging while you watch the hustle and bustle of the city below. In this way, the exterior and interior spaces engage in close dialogue and complement each other. The idea with the portholes was born partly out of a lack of space – with the aim of making the best possible use of the 153 square metres of site area. After relaxing and daydreaming in one of the niches, you will open your eyes and say: Good morning, Vienna!
