A 1,070-foot tower that will become the largest skyscraper on the West Coast received its final approvals from the Planning Commission on Thursday. — sfexaminer.com
Clarke also showed the Planning Commission the actual metal and glass that will be used on the exterior of the building. He explained that the skin of the building has been augmented to add metalwork that will grow deeper and denser at the bottom of the tower. Clarke said adding the metal to the glass exterior will give the building a light texture that will glow in an ambient way.
The metalwork also was used to make the building safer for birds and to help control the flow of water down the structure.
Some people speaking about the project decried the tower as being too large and criticized its design.
