Sunset Gordon's facade looks quite a bit different than the renderings, put perhaps other elements will be added on later. I believed they're required to recreate the Old Spaghetti Factory facade on the ground floor of the new building, since the original structure was too decayed to save.
The nondescript buildings/Arby's to the east of Emerson are probably toast in the near to mid term future. Hudson Pacific Properties also wants to build
an office building on the parking lot next to the Sunset Gordon tower, seen in first black and white pic.
