The installation of blue-tinted curtain wall cladding is finalizing the look of the Millennium Tower, a 60-storey residential development taking shape in Boston's Downtown Crossing district. Since topping off at a height of 209 metres (685 feet) in October, the building now stands as the third tallest building on Boston's skyline. New images from our Forum reveal that cladding installation is approaching the final levels of this Handel Architects-designed tower.

Developed by Millennium Partners MDA Associates, the tower is being constructed on the site of a previous stalled construction project, replacing the earlier flagship location of Filene's Department Store. Located steps from the Downtown Crossing MBTA rapid transit station, the completed development will include 442 residences, a grocery store, and new office space.

While the main volume of the tower and the set-back penthouse levels above were constructed using poured concrete, the mechanical penthouse level's pitched roofline was built using structural steel. A closer look at the large mechanical level reveals the heavy HVAC equipment that will provide heating and cooling for the building. These set-back penthouse and mechanical levels will soon be fully enclosed by blue curtain wall glazing as well, seamlessly blending the upper levels with the main volume below.
