The original 7 World Trade Center was 47 stories tall, clad in red exterior masonry, and occupied a trapezoidal footprint. An elevated walkway connected the building to the World Trade Center plaza. The building was situated above a Consolidated Edison (Con Ed) power substation which imposed unique structural design constraints.
At the time of the September 11, 2001 attacks, Salomon Smith Barney was by far the largest tenant in 7 World Trade Center, occupying 1,202,900 sq ft (111,750 m²) (64 percent of the building) which included floors 28–45.[24][6] Other major tenants included ITT Hartford Insurance Group (122,590 sq ft/11,400 m²), American Express Bank International (106,117 sq ft/9,900 m²), Standard Chartered Bank (111,398 sq ft/10,350 m²), and the Securities and Exchange Commission (106,117 sq ft/9,850 m²).[24] Smaller tenants included the Internal Revenue Service Regional Council (90,430 sq ft/8,400 m²) and the United States Secret Service (85,343 sq ft/7,900 m²).[24] The smallest tenants included the New York City Office of Emergency Management, NAIC Securities, Federal Home Loan Bank, First State Management Group Inc., Provident Financial Management, and the Immigration and Naturalization Service.[24] The Department of Defense (DOD) and Central Intelligence Agency (CIA) shared the 25th floor with the IRS.[6] Floors 46–47 were mechanical floors, as were the bottom six floors and part of the seventh floor.[6][25]
WTC 7 was an office building, less well known than Towers 1 and 2, but like them, it had several different firms in it. And like the other towers, more of them were in the financial services industry, but not all.
There were a few governental offices there. For example, I'm fairly sure that the NYC emergency command center was there (it was somewhere in the WTC and I'm pretty sure it was in number 7. Wasn't Guiliani stupid to locate the emergency command center in the one building that had already been shown to be a major terrorist target! Sheesh!)
