They're working with Jon Hager of Hager Realty Services in the Eastlake area as the local contact for this project. He seems very nice and open to questions; his e-mail is jon at jhager.com, if you'd like to contact him directly. He's been discussing the project with passersby this week, so if you see people out there working, feel free to approach them.
As for the design of the project, he said this:
On the planning front, we have hired a local Seattle architect and the current concept for the property itself is to have retail on the street level, with condos above. There is also a landscaped atrium in the back for the residents, with a parking garage underneath the building.
I asked who the architect is and whether they plan to share conceptual drawings with the community soon. I've also asked about Jim Claeys, whom a longtime Beacon Hill resident named Dan Hagan has been discussing in comments on this post. According to different sources, Claeys is either the past or the present/future owner of this site. I have no idea; I just work here.
