The 800 Fifth Avenue building was built in 1981, and it just got a $46 million face-lift.
Hines Interests Limited Partnership owns the 42-story tower and recently completed major work on the public spaces.
LMN Architects designed the project, which involved demolition and relocation of 24-foot curtain walls to allow for expansion.
The first-floor lobby now extends closer to Fifth Avenue and has better seating areas.
The new west wall and entry area use a point-supported glass curtain wall system to make the lobby more visible from the street.
Part of the second-floor exterior plaza was enclosed to create a mezzanine, with more seating and open conference areas.
A grand stair connects the first floor lobby to the mezzanine.
On the fourth and fifth floors, new glazing has transformed a near-windowless space into Class A offices, with high ceilings and natural light.
New signage was added to improve visibility and wayfinding.
Finishes include marble and stone, stainless steel curtain-wall supports, and accent pieces throughout.
Crews did the work while the building was occupied, which required coordination between contractors and management.
Here is the project team: GLY Construction, general contractor (main lobby, second floor enclosure and glass entry); Turner Construction, general contractor (levels four and five renovation, mechanical, exterior windows); Schuchart, general contractor (core restrooms, elevator lobbies, level 38 conference room, executive parking); Greyscale Design Studio, interior design: MKA, structural engineer; RDH Building Science, building envelope; WSP, MEP engineer; Blanca Lighting Design, lighting design; and Studio SC, graphics and wayfinding.
