Richard Rogers' project for a massive extension of the Jacob K Javits Convention Center in New York is in a state of flux.
The scheme is awaiting a legal challenge from two conservation groups who are determined to see the project killed off.
Bizarrely, this comes as New York mayor Michael Bloomberg and state Senator Charles Schumer are calling for an even bigger development on the site.
According to New York's Architect's Newspaper
, all this confusion comes just a week after state officials issued approvals for the Rogers scheme.
If the current $1.7 billion (£1 billion) development does go ahead, it would increase the size of the existing Javits Center from 76,000m 2
to 110,000m 2
and create a 'super block' which would run from the New York's West 34th to West 40th streets.
But now it will have to confront the legal challenge from the Municipal Arts Society and the Hell's Kitchen Neighborhood Association.
The pair are jointly suing a series of local authorities in Manhattan in a bid to stop the scheme being built. by Ed Dorrell
