Here are the top 10 architectural firms of the past year in Chicago

Chicago’s top architects are helping reshape the city skyline, and over the course of the past year have worked on projects with an estimated cost of some $2 billion.

The 10 firms were involved in some of the biggest projects underway right now along with smaller projects in all corners of the city.

Among them are the 94-story Vista Tower, which is going up along Wacker Drive on the riverfront and will be one of the city’s tallest when it’s done, and the second tower on Wolf Point, the mixed-use development that is helping to transform the area around the confluence of the Chicago River’s three branches.

Also making the list are firms helping to remake the neighborhood around the south end of Grant Park, with projects including the 792-unit NEMA Chicago apartment tower, the 479-unit Essex on the Park apartment tower and the Homewood Hilton tower on 11th Street.
