Taking Baselworld as a leading example of a modern international exhibition, where the halls are animated by the individual exhibitors’ stands, the goods on display and the crowds of visitors, the question of an exhibition hall architecture does not seem to be a primary demand. Architecture is only perceptible in public areas and stairways and only there can an interface with the wider public landscape of the city emerge. The best illustration of this is the round courtyard in Hall 2. Regrettably, this courtyard is only accessible during exhibitions as it is undoubtedly one of the most attractive 【关键词66】 public areas in Basel and, especially during Art Basel in June, one of the most successful urban meeting points in the whole of Switzerland. The City Lounge aims to turn the inward-looking architecture of the round courtyard towards the outside and to make it accessible all year round. How do we design an exhibition hall on the outside? Viewed from the outside, exhibition halls are actually nothing more than a stack of big boxes. They require very few windows and architectural distinctions are deemed as impractical restrictions on interior flexibility. The architectural results are generally composed of vast, monotonous facades of brick as in Hall 2 or glass for Hall 1. To avoid this repetitive sameness, we took a different approach for the New Hall. The New Hall features three exhibition levels. The entrance level, 【关键词69】 the lowest, is at grade with the street and outdoor square, permitting a natural and casual coming-and-going. Ground floor entrances seamlessly link the City Lounge to the existing Hall 1, former Hall 3, the new event space for 2’500 spectators, and a number of shops, bars and restaurants in the foyers. The dynamic sweep of the street level facade reacts to the flows of people and corresponds to the space required at the tram stop and entrances to the exhibition centre and Event Hall. Here, large expanses of glass create the spatial transparency both necessary and appropriate in order to achieve the openness envisioned for the exhibition hall complex and the enlivening of public urban life. This vitalisation and acceptance will be crucial to the long-term success of the "Messezentrum in the city" concept. Above the ground 【关键词56】 will be two exhibition floors. To avoid the “big box” effect, the two upper volumes are offset from each other as separate entities, which indeed they are! The New Hall therefore consists of three individual elements, one on top of the other, each projecting over the street in varying degrees, and allowing them to respond to different urban conditions. From each point of view – whether from the Riehenring, Messeplatz or Riehenstrasse – the New Hall offers a different perception every time and thus avoids the monotony of uniform facade lines. This constant architectural variation is reinforced, paradoxically, by applying a homogeneous material (aluminum) over all exterior surfaces. The facade of articulated twisting bands strategically modulates and reduces the scale of the large exhibition volumes to its surroundings. This is not simply a decorative element but a practical means to regulate the fall of natural light on adjacent properties and to frame specific views from individual spaces, primarily the social areas above the City Lounge, towards the public life of the city.
