NOTES: The factory is a hexagonal shape with a paraboloid roof, with each wall of the hexagon divided into nine bays of built-up precast concrete units.
NOTES: The Rockefeller Center is a complex of 19 commercial buildings covering 22 acres between 48th and 51st streets in Midtown Manhattan. The original complex of 14 Art Deco style buildings, commissioned by the Rockefeller family and named after John D. Rockefeller Jr., was designed by an association of architects under the leadership of Raymond Hood and was built in 1931-1940. The 70-storey GE Building (known as the RCA building until 1988) forms the centrepiece of the complex and opened in 1933.
NOTES: Hill prepared designs for a new house, studio, cottage and garden with fountain. When the house was built it was in Trafalgar Square, so named when it was laid out in 1812, but the square was renamed in 1937 to avoid confusion with Trafalgar Square in the centre of London.
