Milwaukee plans to build a new, unnamed project featuring up to 55 floors constructed largely from engineered mass timber materials. If completed, it would be the world's tallest timber skyscraper, surpassing the current record-holder, the 25-story Ascent tower. The project will include residential units, office space, retail space, hotel rooms, and parking spaces.
