Worcester is home to the three buildings in Central Massachusetts with more than 20 stories, including the 24-story Glass Tower offices, the 21-story office complex Mercantile Center, and the 24-story residential tower The 6Hundred. However, no new skyscrapers have been built in Central Massachusetts in the last 35 years. In Boston, Mayor Michelle Wu has proposed building more residential high rises as a way to create more housing and address the affordability crisis in Eastern Massachusetts.
