Naseljivi mostovi

Korištenje mosta za nešto više od transporta ljudi i dobara nije nova stvar (Rialto Bridge -Venice i Ponte Vecchio -Florence) ali njihovo korištenje za nešto više od malih kioska, za stanovanje, je recentniji kocept najrazrađeniji kod Steven Holl-a.

[Steven Holl’s  Bridge of Houses project]

Kasnih 7Otih i ranih 80tih Steven Holl je napravio par teorijskih projekata za Bronx i Manhattan, publiciranih kao Pamphlet Architecture 1 i 7. Gymnasium Bridge projekt spajao je južni Bronx i otok Randalls te Bridge of Houses projekt predlažući stanovanje na High Line koji se prenamjenjuje u manje “naseljivo” ali ipak ne manje ambiciozno.

About a decade later, in Holl’s winning but unfortunately unbuilt entry to the Amerika-Gedenkbibliothek competition for Berlin’s main library, he made a massive bowstring truss spanning from one arm of the building to the other the children’s library, where the sloped floor would allow kids to lie down while reading. Unlike the two projects above, this design makes a strong formal statement with the bridge, emphasizing the importance of it in the project and Holl’s thinking on this architectural element.

It took Holl another 20 years before he actually built what I’m calling a habitable bridge, with the Linked Hybrid mixed-use development in Beijing, China, now under construction. According to the architect, “This ‘city within a city’ envisions urban space-as well as all the activities that can support the daily life of over 2500 inhabitants. The 8 towers are linked at the 20th floor by a ring of cafes and services.”

But, as can be seen in the plans and sections below, functions like a cafe, bookstore, and even a swimming pool are located in the ring between the buildings, not just alongside the tower cores. So this bridge becomes circulation and something else, whatever function is ascribed. Aside from the swimming pool (something I was shocked to find between buildings, given the water’s weight, but the column free span does make it the natural place for it) the other spans look more flexible, so their functions will probably change over time; will a bookstore survive 20 floors up? Surely this ring brings to mind Le Corbusier’s Unite d’habitation in Marseilles, France, whose raised shop level is used mainly for offices; mixed-use yet, but transformed from its intentions, as should occur here.
