BiG’s 2 WTC was designed for News Corp, a media company not a tech company.
BiG’s design had at least 7 very different floor layouts. Less ‘very large’ floors. Aimed at multiple smaller newer tech/media companies which might fill a ‘section’ or a larger company with many divisions to be split across a few of them. My guess is that Fox was in talks to take the bottom 2 or top 3 ‘sections.’
Much like ESB, Foster’s design has a large base (~20% of office floors), nearly uniform main tower body, with the only major setbacks after the base being on the top 10-15 floors. Designed primarily for ‘old school’ financial tenants and law firms in the tower portion.
If Silverstein builds this on spec my guess is that he would build Foster’s design because its almost certainly a bit cheaper to build, hews closer to what the WTC historic tenant base is expected to desire and less controversial.
Personally, I think he’s saying this to get attention, but I welcome being wrong. This isn’t SJP Properties building 11 Times Square, a 1.1M structure on spec. This is a building 2.5 times larger and probably 4 times as expensive when there are new half empty buildings next door.
If he builds it they will come…though it might take 15 years to fully lease out and will contribute to an office glut that will inhibit office construction until the 2030s.
