Viennese architects Kohlmayr Lutter Knapp have come up with an adaptive newÂ use for the empty retail spaces dotting the Austrian capital:Â hotel rooms.Â Mostly around 250 square feet in size,Â the small disused shops are being converted into street level lofts nicknamedÂ Urbanauts. The master plan calls for different Urbanauts clustered together in one neighborhood making up a decentralized hotel, with services dotted around the area: the coffeehouse next door is the breakfast room, the hammam across the street is the spa, and the hotel bar is that trendy watering hole around the corner. Amenities and local tips are plotted on a map provided in the room. And the lobby? It’s the whole city. The concept is designed to offer guests a real feel for the surrounding urban space, and an alternative to the run-of-the-mill tourist traps. Guests step out of their room right onto the sidewalk, but the spaces still offer a private and convenient retreat for travelers. Guests can decide how much of the view outwards – and inwards – to reveal, using a clever blind system. And as part of the emphasis on locality, artists from the immediate environs are invited to design the rooms. Rates top out at around â‚¬120 per night per Urbanaut, including breakfast and the use of two bicycles. Space helmets not included.
