115 Winthrop Square includes Boston's next great public space: "The Great Hall" will be a year-round gathering place, programmed with events.

Situated in the Financial District of Boston, 115 Winthrop Square will give new definition and vitality to this part of the city. The massing of the tower is designed to be a beacon on the Boston skyline, while showing deference for the adjacent One Winthrop Square and other neighboring Art Deco-era buildings built in the 1920’s and 1940’s. Though technically one tower, the massing of the building splits into two as it rises, and each form is treated differently on the skyline.

115 Winthrop will seek to enhance and revamp the existing Winthrop Square, creating new open space to serve Boston, and linking together several other adjacent outdoor spaces. A grand new public space entitled the ‘Great Hall’ will anchor the building and traverse the site between Federal and Devonshire streets. This space is envisioned as a year-round gathering place with programmed activities such as art shows or farmer's markets, as well as more permanent retail establishments and restaurants.

The site’s through-block nature creates a T-shaped plan and allows the tower to relate to two different sets of context. To the west, from Winthrop Square, a much more formal, enclosed portal threshold is utilized, creating a dramatic emergence into the Great Hall space. The entry scales down the overall tower so as to complement and show deference to One Winthrop Square. On the busier Federal Street side, a large glass entry façade in an oversized stone frame will blur the boundaries between indoor and outdoor space. Above the Great Hall, the office portion of the building gently curves around Winthrop Square to the west, creating an inflection in the massing. Adjacent to Winthrop Square, the building shears back above the office to maintain a consistent scale to the Devonshire Street wall, and a comfortable, intimate feeling within the Square. The undulating nature of the curtainwall creates strong vertical impressions, and is intended to catch and reflect the light in a dynamic fashion. At the tower top, the undulation becomes more pronounced, creating a unique form and giving the building a skyline presence.
