The two office towers share an entrance plaza that was in need of updating. The plaza presented several challenges: it is shaded by the towers for most of the day and the two towers create a wind tunnel through the plaza. The area is on bay fill and the soil is unstable and stays wet and saturated. The existing plaza had a grid pattern with no clear entrances to the main doors.
