This is Parcel P, which is "described in a notice that was distributed around the neighborhood as: one wood-framed, 5-story building with 182 units and 127 parking spaces" per the
Hayes Valley Farm website.
Parcel P will be market rate housing. O is supposed to be 100% affordable housing.
The Market and Octavia Neighborhood Plan states: "the physical fabric of the surrounding residential district is extremely fine-grained, with small individual residential buildings on narrow lots. This pattern should be extended onto Parcels O and P, by subdividing it into narrow lots that reflect the prevailing 25-foot rhythm of parcels in the area, and encouraging the development of individual buildings on these lots."
A single wood-framed, 5-story building doesn't seem to match that requirement. Nor does it match Developer Build Inc's original plan to break the design up among various architects. Maybe they'll just use a facade to make it look like many smaller buildings. Can't wait to see some renderings.
