The offices of J.P. Morgan were originally designed by Gensler Associates. From the building's opening, J.P. Morgan's computer systems were served by of cable, a large portion of which was fiber-optic cable. On each story, the corners contained private offices, while the rest of the perimeter was unobstructed, allowing the interiors of each story to be illuminated by sunlight. Most workspaces were designed as cubicles of similar size. Though departmental heads were given offices, their furniture was standardized and their office sizes were similar. The executive offices for J.P. Morgan's senior managers, chairman, and CEO were on the 20th story of the 55 story building; this was an intentional choice as their executives who wanted their employees to be "spread equally around them". Mancini Duffy designed the furniture for J.P. Morgan at 60 Wall Street.
