For nearly 100 years, the JL Hudson's Department Store in downtown Detroit stood as a mecca of shopping – the 25-story structure at one point holding the record for world's tallest retail building. Then in 1983, following a downturn of the Detroit economy, the department store was closed. Its implosion followed in 1998. nnounced by Detroit-based development group Bedrock, the site is set to receive a brand new 1.2 million-square-foot development designed by SHoP Architects and consisting of a nine-story retail podium and a 52-story, 734-foot tower that would claim the title of Detroit's tallest building.
