The project has already passed the Planning Commission with conditions, one of which is to re-design the building and submit the new design to Planning Department staff to ensure it complies with the design regulations in the Zoning Overlay. They had to agree to that condition or the Planning Department would have recommended denial of the PUD. Yet, they still brought their design with them to the Planning Commission hearing as if that design is still going forward. I expect they will still bring it to the LUZ meeting also.
As far as I'm concerned, it's not the modern design so much (although not my personal favorite style and needing high quality materials so it doesn't look cheap) as the building's mass and scale. An architect I know described it as "5 pounds of stuff shoved into a 1 pound bag." I think that's right.
I wouldn't count on LUZ requiring more parking. The Planning Commission did not make that a requirement, even though community members other than RAP spoke about their concerns. If it's a concern, you should contact the LUZ members or Councilman Corrigan.
