This design event takes place at a public park in the city of Boston, and it focuses on serving the given theme: A Long Walk Through the Park. Another important aspect requires the practice of long and thin architecture, and its implications upon site layout, program arrangement, indoor/outdoor spaces, circulation and more. I choose to focus on circulation, which generates the following levels: from the ground through the building’s exterior (images: 1, 2, 3), through roof gardens (images: 4, 7), interior enclosed (images: 5, 6), under the building (images: 8, 9). Perhaps this design behaves like a bridge, which creates a shortcut through the park and over the water feature. Its dominant programs, the art gallery and the library run along the length of the building, intertwining with each other. Many spaces appear from this gesture and the need to connect them adds other layers of transitions from the ground to the building, from exterior to interior, from the roof gardens to the indoor spaces, and vice versa.
