The Design Commission voted unanimously at the 04/24 meeting to not recommend the density bonus needed to build this project as it currently stands. So it's still a work in progress.
The amount of parking was the issue with the commissioners. Public parking garages are part of Brandywine's business, so incorporating more parking than normal for such a project was done on purpose to allow for significant public use of the parking garage.
The Downtown Alliance spoke in support of the project because of the amount of parking. They see a lack of downtown parking as a serious issue.
The sky lobby (and glass elevators) is planned as a public space.
Here are some fuzzy screen captures from the Design Commission presentation.
