Prior to operating under the name Landmark Tower Corporation, this location at 100 Covelo Ave was Adelphon, Inc which was incorporated in 1971. According to wikipedia,
The prototypical Landmark tower, also known as an Adelphon tower, is a tripod in shape with three legs that rise to meet each other about a third of the way up. The legs taper down from larger footings to a thinner middle and then expand again to the point where they meet. The outer cords continue all the way up to the top of the tower in one swoop, but the inner three loop around into each other, creating a central ovoid and voided core. Aside from its unique appearance, the Landmark tower design has several advantages compared to the typical free standing lattice tower, with less wind resistance and a reduced amount of steel required for construction.
