That excavator first rolled out here on La Branch and Binz last summer — and 11 months later this is how the site looks: Catty-corner from the Children’s Museum, the Museum Point Professional Building appears to be all but complete. The 4-story building at 1401 Binz was originally planned to be 30,000-sq.-ft., with retail on the first floor, a clinic and offices on the middle floors, and some kind of residence (“with a garden terrace”) up top. A 160-car parking garage was also planned.
