2. Das Park Hotel
Das Park Hotel is located in Linz, Austria and is actually a number or repurposed drainpipes that have been turned into rooms. It is a great example of how we can reuse materials and things. The workers only made use of varnish and wall paintings to transform the pipes into a cozy accommodation. The space of each room in this hotel is about 2 square meters and it occupies a bed, light, power and sufficient ventilation. You can also fit your luggage in the room. Bathroom and kitchen facilities are not too far away from the pipes, but you need to pay for those services.
