27 Union Square West is a 5-story early-modern building that was built in 1959 by the architect Max Siegel. The east side of the building, facing Union Square Park has a curtain wall of aluminum, glass, and blue-green panels. The north side of the building is clad in white brick with horizontal window bands. The ground floor was occupied by the iconic Coffee Shop for over 31 years, with office space on floors 2 to 5. Union Square provides an excellent transport hub with access to the L, N, Q, R, W, 4, 5, and 6 trains, its renowned farmers' market, restaurants, varied retail, including the sprawling Barnes & Noble on the north side of the square, and the always popular W Hotel with its buzzing bar scene.
