Construction activity is underway at One Madison Avenue in the Flatiron District, where the 13-story full-block structure is being renovated and expanded with a new 18-story addition. Designed by Kohn Pedersen Fox and developed by SL Green, the project will stand 27 stories and yield 1.4 million square feet of Class A office space. Helping to develop and finance One Madison Avenue’s future are the National Pension Service of Korea and Hines, contributing a grand total of $1.25 billion in construction financing. The property is bound by East 23rd Street to the south, Madison Avenue and Madison Square Park to the west, East 24th Street to the north, and Park Avenue South to the east.

Earlier this year, Porcelanosa Group revealed its plans to renovate and expand its existing flagship location at 202-204 Fifth Avenue in Manhattan’s historic Flatiron District. Following an expanded visibility study, the ceramics manufacturer has returned to the Landmarks Preservation Commission (LPC) with revised proposals that reduce street-surface views of the building’s rooftop mechanicals.
Porcelanosa’s prominent flagship location in the Flatiron District of Midtown, Manhattan could receive a major vertical expansion and interior renovation if approved by the Landmarks Preservation Commission. New proposals, dated April 16, 2019, are arranged by CetraRuddy Architecture in collaboration with preservation consultants Higgins Quasebarth and engineering consultants Walter P. Moore.
