Barbara M. Brakman 75 Plaza LLC 240 Greenwich Avenue Greenwich, CT 6830

Pursuant to Section 25-307 of the Administrative Code of the City of New York, the Landmarks Preservation Commission, at the Public Meeting of February 17, 2015, following the Public Hearing of the same date, voted to grant a Certificate of Appropriateness for the proposed work at the subject premises, as put forth in your application completed on January 22, 2015, and as you were notified in Status Update Letter 16-8031 (LPC 16-6756), issued on February 17, 2015.

The proposal, as approved, consists of the installation of two-over-one double-hung aluminum windows in new openings at selected locations at the north (West ), east and west facades at the building's thirty-second story, by replacing portions of historic cast-aluminum spandrel panels and related brick masonry back-up walls, as well as portions of ventilation louvers; the related replacement of selected portions of ventilation louvers at the thirty-first and thirty-second floors with solid aluminum spandrel panels to match the surrounding historic spandrels; and the replacement of historic beige terrazzo paving at the West 52nd Street entry portal, featuring a 3'-8" square pattern formed by brass strips, with new white terrazzo paving to feature new brass divider strips in a recitlinear pattern. The proposal, as presented, included brass divider strips in an approximately 6'-8" by 3'-8" pattern. The proposal was shown in drawings 2 through 29, with a cover sheet, dated February 3, 2016, prepared by Kohn Pedersen Fox Associates P.C., and presented at the Public Hearing and Public Meeting. In reviewing the proposal, the Commission noted that 75 Rockefeller Plaza (aka 15-19 West , 14- 36 West 52nd Street, originally Esso, later Warner Communications, then Time Warner Building), is an office tower, designed by Robert Carson and Earl Lundin, with , and built in 1946 as part of an Art Deco-style office, commercial and entertainment complex. The Commission further noted that Certificate of Appropriateness 15-8735 (LPC 15-5820) was issued on June 9, 2014, approving alterations to the building's base at the West 51st and West 52nd Street facades, including the replacement of the historic bronze and glass infill at the deeply recessed glazed central entry portal at the West 52nd Street facade; and that Certificate of No Effect 15-9264 (LPC 15-7590) was issued on June 20, 2014, approving comprehensive window replacement at all facades, with all window components to have a painted finish (Benjamin Moore "HC-167 Amherst Gray").

With regard to this proposal, the Commission found that the proposed removal of selected portions of the historic ridged cast-aluminum spandrels from selected bays at the building’s 32nd story will allow for the change to office use from mechanical space at this floor; that these removals will maintain the original elongated character and continuous vertical design of the spandrels at the roof parapets at the building’s four primary tower facades; that the proposed installation of windows in place of these spandrel sections will establish continuous rows of windows at this story, which has been altered previously by the installations of windows at selected bays, and therefore will serve to regularize the building’s fenestration pattern and enhance the historic uniform horizontality of window bands throughout the façades; that the proposed windows will match the historic windows in terms of configuration, operation, dimensions, details, materials and finish; that these changes will maintain the historic uninterrupted vertical character of the spandrel bays and the alternating, rhythmic visual relationship of the bays and the limestone piers at the building’s facades and crown; that the proposed replacement of the terrazzo paving at the recessed West 52nd Street entry portal is warranted by its deteriorated condition; that the terrazzo material of the proposed paving will match that of the historic paving at this portal and at selected other locations throughout the landmark site; that the brass material and rectilinear design of the proposed paving divider-strips will match those of the historic divider strips; and that these features of the proposed paving will help maintain this historic paving type at the portal as well as the consistency of historic terrazzo paving at selected locations throughout the landmark site.

However, in voting to approve this approval, the Commission stipulated that the joint patterns formed by the divider strips at the terrazzo paving at the West 52nd Street entry portal and at the adjacent interior flooring be coordinated and consistent; and that two final signed and sealed Department of Buildings filing drawings showing the approved proposal be submitted to the Landmarks Preservation Commission for review and approval.

Subsequently, the Landmarks Preservation Commission received a drawing, dated August 8, 2016, incorporating a sightline study, and prepared by KPF; and final drawings A-138.00, A-139.00, A-204.00, A- 205.00, A-301.20, A-311.00, A-311.10, A-317.00 through A-322.00, A-334.00,A-335.00, A-335.10 and A- 410.00, all dated (revised/issued) May 16, 2016, and A-230.00 through A-233.00/Enlarged Tower Elevations/Bulkhead, all dated (revised/issued) September 25, 2015, all prepared by Michael D. Greene, R.A./KPF; and (revised) A-231.00 through A-233.00/Enlarged Tower Elevations/Windows-Louvers, all dated June 21, 2016, and received by the Commission on December 7, 2016, and A-369.00, A-374.00, A- 375.00 and A-376.00, all dated (revised/issued) June 21, 2016, and A-388.00, dated October 2, 2015, all prepared by David May, R.A./Superstructures.

Accordingly, the staff of the Commission reviewed the materials and drawings, and found that the proposal approved by the Commission has been maintained, and that the drawings additionally show the installation of paving at the West 52nd Street entry portal, to consist of greyish-white terrazzo (D. Magnan & Co., Inc. Page 2 Issued: 12/12/16 DOCKET #: LPC-18-4314 Matrix 3171-R) with 1/4-inch brass divider strips, and paving at the adjacent interior space, behind the recessed glass curtain-wall entry infill, to consist of the same greyish white terrazzo; as well as alterations at the main tower roof, consisting of the construction of a penthouse elevator-machine-room, to be set back at all facades from the tower-roof parapets, and to feature an exterior stair at the south facade and glass perimeter railings at the roof, and the installation of live 'green' roofing at both the new machine-room penthouse and main tower roofs, to consist of continguous trays containing planted vegetation. The Commission finds that the new terrazzo paving is in a color and scoring pattern that is coordinated and consistent with the color and pattern of the adjacent interior terrazzo flooring immediately beyond the glass curtain-wall entry-infill; and the Commission also finds, in accordance with the provisions set forth in the Rules of the City of New York, Title 63, Section 2-19, that the rooftop addition consists solely of mechanical equipment, as defined by the Commission's Rules; that the addition will not result in damage to, or demolition of, a significant architectural feature of the roof; and that the addition will not be visible from a public thoroughfare. Based on these and the above findings, the drawings have been marked approved with a perforated seal, and Certificate of Appropriateness 19-6364 is being issued.

PLEASE NOTE: This permit is being issued contingent upon the Commission's understanding that the new windows will match those approved in Certificate of No Effect 15-9264 in terms of design, dimension, detail and finish; and also upon the Commission's review and approval of shop drawings related to the approved spandrel replacement prior to the commencement of work. Promptly submit the requested materials to the Commission staff.
