[citation][nom]wdmfiber[/nom]I don't think the 2.4 acres is accurate. My lawn is bigger than that, granted I'm on 302 acres. But a billion dollars! ...seriously, there wouldn't be room for the employees. Let alone decent sized offices or computer/meeting rooms. The Microsoft Campus in Redmond Washington is almost 200 acres, just in building space. LOL![/citation]
An Acre is 43,560 square feet. 2.4 Acres is 104,544 square feet. The building is unlikely to fill the entire lot, it will probably have a sidewalk around it and maybe a small lawn and some driveways. So to allow for that, and also to simplify the math, I'm going to call it 100,000 square feet per floor.
The article says 7 to 11 floors, so approximately 700,000 to 1,100,000 square feet. Plus it will probably have two or three levels of basements.
I think they can do it on a 2.4 acre lot, although my first reaction was this is an insane waste of money. They probably need a small office in London, which they should lease, and they should put the million square foot office building somewhere that land, and everything else, is a lot cheaper
