The project, called Old Port Square, is led by Tim Soley, president of the Portland-based development firm East Brown Cow, along with Safdie Architects. It centers around a four-acre block bordered by Exchange, Union, Fore, and Middle Streets, an area currently dominated by office buildings.
"We have a city that is now rebirthing for retail activity, for people living downtown once again," Soley said.
Over the last 16 years, Soley has strategically acquired properties in this block. His latest vision includes a 30-story hospitality and residential tower—approximately 380 feet tall. The top of the tower would include a publicly accessible sky lobby and restaurant that offers 360-degree views of Casco Bay and the White Mountains.
