Millennium Tower is the height of luxury in the SoMa District of SF. The development is comprised of a modern 60-story high-rise tower with condos and a 12-story tower with open loft-style homes.
Millennium Tower is more than just a high-rise condo building. It's actually a collection of three distinct residences that share a long list of amenities. There is a 60-story building that has two types of homes: The Residences are from floors 2 - 25, and the Grand Residences are from floors 26 - 60. There is also a 12-story tower that has 53 open loft-style condominiums called the City Residences. The City Residences are in more of a modern loft style, while the Grand Residences are more luxury condominiums.
