750 Third Avenue

 office building, skyscraper

436-foot, 34-story International-style office building completed in 1958. Designed by Emery Roth & Sons, it is similar to and connects with 485 Lexington Avenue to the east. The building is L-shaped and employs a wedding cake form, with multiple setbacks tapering from the base to the upper tower.

The facades are clad in a curtain wall of silver metal mullions, reflective glass, and black metal spandrels. At the middle of the east facade along 3rd Avenue there is a 4-story atrium entrance composed of marble and granite. It spans four bays at the bottom two floors, with two sets of revolving doors framed by regular doors, flanked by two bays of large plate-glass windows, black polished granite piers separate the bays at the ground floor. Above, rounded columns of highly-polished grey stone extend upwards between the tall expanses of glass at the 2nd floor. The two outer columns form the rounded ends of framing walls of the same stone that line the edges of the recessed area at the 3rd & 4th floors. The center column continues to the top of the 4th floor as a traditional column, bisecting the recessed area, which angles back at the 3rd floor with sloped skylights. The entire entry is framed by grey stone.

The rest of the ground floor is clad in black granite, with metal-and-glass storefronts recessed behind the square piers, and a metal band course along the top. At the far west end of the north facade on 47th Street there is a 1-story section of loading dock clad in beige brick. The west elevation is also clad in beige brick, with bands of windows along each floor, which matches the opposite and intersection south section of the adjoining building.

The west half of 750 Third's north facade (and also the narrower west end of the south facade) has setbacks above the 6th, 8th, 11th, 13th, 16th, & 18th floors, with a lower roof line at the 20th floor. The east half of the north, south, and east facades set back above the 11th floor, as well as the 13th & 16th floors. The upper tower rises sheer from this last setback, with narrow wings on the north and south sides slightly recessed from the rest of the tower. These wings end just below the mechanical floors that mark the building's main roof line. Above the lower roof line at the west side, the rectangular concrete core projects from the main, eastern tower, with a single bay of wide horizontal windows on the north and south elevations.

The ground floor is occupied by Blackwells Pub & Restaurant, a Bank of America branch, Ten Thousand Coffee, TIAA Financial Center, Just Salad restaurant, and Spiff for Men hair salon.
