“The landlord at that point demolished the floor and white-boxed it and turned it into a marketing center for the building,” said Mikael Nahmias, the Cushman & Wakefield broker who, along with Jared Horowitz, acts as leasing agent for the East 57th Street building.

Within four months, however, executives at Coller Capital, a boutique private equities firm, came upon the 11,500-square-foot floor plate and its views of Central Park and the East and Hudson Rivers and made a decision to relocate from offices at 410 Park Avenue following an agreement by the landlord to custom-build the space to the tenant’s specific preferences.

After the jump, Mr. Nahmias reviews the plan with The Commercial Observer and discussed why officials at Coller Capital chose to ink a deal earlier this month at Naomi and Andre Althoz’s 32-story office tower.
