For a cool $49.9 million, you can operate inside the confines of this trophy office on W. 54th Street. Located across the street from the Museum of Modern Art in Manhattan, this palatial estate turned luxury office has been reduced by nearly $15 million already, and could fetch you around $3,000 per square feet on today's market. Quick calculations has that up to 16,000 sqf and more. Holy sh*t.

The gorgeous century-old limestone exterior and glass penthouse are amazing, and the fact that Philip Lehman and his son Robert (who headed Lehman Brothers for decades) once lived here is pretty nuts, too. Whether you're an executive, fancy collector, or just a fan of dope architecture, hit the thumbs for a closer look at the most expensive office space in the world.
