As of late bus stops are proving to be unexpectedly fertile grounds for architectural innovation. Swiss architects Vehovar & Jauslin are the latest to try their hand at the task in the form of a seemingly floating structure that provides shelter for a bus hub in Aarau, Switzerland. The canopy was realized with the help of engineering firm formTL who appear well-versed in undertakings of a similar ilk. The covering's cool tone derives from a blue-tinged upper membrane that filters through a clear underbelly. This ETFE-foil skin is printed with a bubble-pattern and filled with air to create a curved surface. A steel ring hugs the canopy's perimeter and helps to protect its fragile inflated contents. The entire amoeba-like form sits atop metallic columns that double as light sources once night falls. Sheltering a ground area of 10,764 square feet, the structure is pierced by a central three-pronged opening that welcomes natural light into the station. The project was first begun some nine years ago before its eventual completion late last year.
