New York City real estate climbed to new record heights as hedge fund Citadel agreed to pay $300 per square foot for space in a luxury office tower at 425 Park Avenue in Midtown Manhattan.

Previous peak rents in New York topped out at about $200 per square foot. The property’s developer, L&L Holding Co., put several plans in play to justify the hefty price tag. They include:

  • An exclusive restaurant managed by Daniel Humm and Will Guidara, the duo behind the Eleven Madison Park and Nomad.

  • Ventilation that filters 95 percent of the outside air,according to Crain’s New York.

  • A community space on the 26th floor where tenants can mingle and meditate in private rooms.
