Mobile hostel can shift Stockholm!

I have been working on a student project of Stockholm City center. Today if you go to the area around Sergelstorg, Brunkebergstorg and Gustav Adolfs torg( So called TreTorg zone), you will pretty much feel you are always at the back side of stores in many spots. and the waterfront area besides Parliament are left over and seldom regarded as a place for recreation. Well in other cities like Amsterdam the waterfront is creatively tailored to make the city life enjoyable and pleasant, you can always find cruise going in the cannel, people water flowers on the top of their boathouse and so on.

Another problem is city center is pretty void during night. The reason can be found in this figure:
Over 40000 people in daytime but less than 1000 at night in this area so the street is not under effective surveillance of inhabitants. People who passing by this area might be scared because it’s so empty, there’s few people to get help in case of trouble!

I am inspired by this project made by 2 Swiss artist-duo L/B (Sabina Lang and Daniel Baumann)., they designed a mobile pavilion called Hotel Everland, it is a Hotel with only one room. It includes a bathroom deluxe, a king-size bed and a lounge. It has been brought to Yverdon, Burgdorf, Leipzig, Paris and some other cities, and was put in different location by crane.

So this is my idea. Mobile hostel units!

In daytime they can be put on cruise boat and tourist can enjoy the beautiful waterscape around Stockholm. In the evening they will be moved and setup in different spot at city center, independent or aggregated, to make the area safe and colorful at night.

Later If I have time I will make a model of this idea.
