Year after year, the students of Oporto School of Architecture are invited to think on a temporary bar to represent their institution with the expected dignity, as an outstanding architectural object. The given implantation, the fast construction and the low budget are some of the premises which must be considered.Taking advantage of the IKEA build-by-your-own world, the project is a parallelepiped made out of different depth storage boxes which give it the modular diversity on its textured skin. After winning the competition, some adjustments were done and the bar grew to 4,7 metre high, standing as a visual reference. Built in one week with the help of students, it was completed one month after the jury announcement. A total of 420 boxes were first fixed on a wooden structure and then attached to the main metal structure, on site. A huge LED net was fixed behind the boxes, allowing the bar to dramatically change its appearance: by day a white abstract and closed volume; and by night a box of changing light following the DJ set.
