The interior design of the William hotel from New York is the work resulted from the collaboration between In Situ Design, Lilian B Interiors and artist William Engel. By blurring the lines and harmony between the architecture, interiors and art, have created a three-dimensional habitable painting. Each floor of William hotel has a different color. The ceilings, walls, carpets and bed linen are in a monochromatic palette of blue, turquoise, pink, orange or yellow. The abstract paintings of large sizes are placed in colored niches decorating the corridors painted in bright white. The abstract shapes extend in rooms where guests can experience various colors.
