For its Living Cities competition, Metropolis magazine asked participants for solutions to the housing crisis facing New York. According to the magazine, the city is expected to gain a million more residents by 2040, placing a strain on housing and transport. The winners have now been announced, and include a twisting tower on the High Line and a multi-transport, entertainment and residential hub.
The competition sought designs that were based within the five boroughs of New York, that incorporated a 30-40 story residential tower and that included an, "innovative structural steel system." Participants were also asked to consider sustainability, multi-use strategies, lifestyle amenities and multi-generational design.
Vivo was designed and submitted by Andrew Duffin and NBRS+Partners. It reworks the concept of New York's High Line, a redevelopment of the West Side Line railroad that was opened in 1934 before falling into disuse and which has spawned similar projects in places such as Sydney. The concept "engulfs" the High Line and extends it vertically.
"It's a hybrid structural system where the triangulated diagrid system acts as an exoskeleton providing lateral stability and vertical support," explains the Vivo team. "This frees the internal space from needing internal intermediate structure allowing ultimate flexibility for remodeling or use changes over its lifespan. VIVO is alive and responds to the daily and seasonal energy of NYC."
The second winner was designed by Chad Kellogg, Matthew Bowles and Nina Mahjoub of AMLGM. Urban Alloy is a huge road and rail transport interchange, with the sprawling steel tendrils of the structure appearing to suck in the surrounding train lines and freeways proving a central connecting point for people across New York. In addition to the transport hub, the building also houses residential units and entertainment spaces, made easily acccessible by the transport links.
"Unlike concrete structures that benefit from a very regular floor to floor height because of the need to reuse formwork, steel structures can efficiently be constructed with each unique member cut by an automated system," explains the Urban Alloy team.
The winners each receive US$10,000 of prize money.
