The designs also indicate plans to convert 69,845 square feet of basement space into parking at the 41-story Financial District tower known as the “pregnant building.”

“We are pleased to be working with the city to transform the plaza outside 100 Federal St. into an enclosed and vital gathering space for the downtown community,” said Bryan Koop, Boston Properties’ senior vice president and regional manager. “The weather-protected atrium … is planned to complement the outdoor space at Post Office Square Park and will be programmed with restaurants and events to bring a more active and lively streetscape to the base of the tower.”

Current designs include 8,500 square feet of retail, 500 square feet for kiosks and an 8,990-square-foot winter garden in an angled atrium with a glass facade.
