Wow, a very unexpected but impressive proposal! The design looks very high-quality. I can't imagine this will make it past the NIMBYs unscathed, but it may be far enough down Market from the heart of the Castro to be able to actually get built (if the economic conditions improve in time).
There was also a 15-story affordable senior housing proposal for the triangle lot across Duboce:

If these two get built, this would create a great gateway to the upper market/ Castro area and a new node of density and height in an otherwise low-mid rise area. Very exciting!
