拢150m complex planned for top of New York subway may give way to performing arts centre

A Grimshaw-designed transport centre on the site of the former World Trade Centre in New York could be replaced by a theatre designed by Frank Gehry.

It has emerged that the $1.19bn (拢508m) Fulton Street Transit Centre (FSTC), a subway station that was to have been topped with a glass structure designed by Grimshaw鈥檚 US office, could now have a performing arts centre designed by Gehry built over it to save money and time.

The Lower Manhattan Development Corporation (LMDC), the body set up after the 9/11 attacks to organise the rebuilding of Ground Zero, has launched a 30-day feasibility study into building the Gehry centre on top of the subway station instead of a nearby site earmarked for it.

Budget cuts and design changes have held up the construction of the FSTC since it was announced in 2004.

The Metropolitan Transportation Authority (MTA), which is commissioning the FSTC, has already scaled back its plans for Grimshaw鈥檚 $295m (拢150m) structure. The initial design, unveiled in 2006, envisaged a glass atrium that would rise 50ft above the ground. This was reduced to 10ft last year.

The MTA then revealed last month that it would be 鈥渟treamlining the work鈥 further after failing to find a contractor to undertake it.

It鈥檚 very early days. The ideal thing, though, would be if the MTA built what it said it would.

The Grimshaw design was to have housed a glass funnel allowing natural light into the station below. If the Gehry theatre is built above the transit centre, the station will receive no natural light at all.

The FSTC will be the main hub for downtown Manhattan and is expected to handle 275,000 passengers a day once the World Trade Centre has been rebuilt.

The station鈥檚 substructure has been designed by Arup.

An MTA spokesperson said: 鈥淭he LMDC is studying the proposals.鈥 He added that speculation that Grimshaw鈥檚 designs had been scrapped already were 鈥減remature鈥.

An LMDC spokesperson said: 鈥淚t鈥檚 very early days. We鈥檙e looking at the feasibility of doing it. The ideal thing, though, would be if the MTA built what it said it would.鈥

Grimshaw declined to comment.
