There is no market for any unsubsidized new construction in Detroit. If you want taller buildings [[and I'm not sure why this should be a priority), then you need even deeper subsidies, simple as that.

You can build the tallest building on earth in Highland Park if it suits your fancy. Just come to the plate with massive subsidies.

As to the Hudson site, Gilbert has never built anything in his life. He isn't a developer. If something is eventually built there, it will be deeply subsidized regardless of building type.
