MILWAUKEE – A new building proposal could change Milwaukee’s skyline and set a world record. The city announced plans for multiple mixed-use buildings that would replace the Marcus Performing Arts Center parking structure at Water and State. While one building would become the state’s tallest, another would be the world’s tallest mass timber building. The proposed mass timber building would be the third of its kind in Milwaukee. The Ascent on Van Buren was the most recent build. “These are more popular in Europe and other countries,” said North Shore Fire Rescue Chief Robert Whitaker. Whitaker said don’t let the wood fool you; with building code requirements and updated technology, mass timber buildings are fire safe. …The project would potentially the tallest building in the state. Currently, the tallest building in Wisconsin is the US Bank Center, which stands 601 feet tall. The proposed building would stand 613 feet.
