171 Tremont is a 20-story luxury residential tower located in Boston, Massachusetts. Facing the historic Boston Common, the tower occupies a deeply meaningful part of the city. GRADE partnered with Elkus Manfredi Architects to design a structure that would take advantage of the physical and contextual conditions and present a fiercely modern architecture and residential experience. The front facade is clad with expansive glass panels set within large, multi-story bronze frames, beveled to catch the sunlight, which offer residents a unique glimpse of their homes when viewed from across the street and park; and from the interior, frames act as portals to the world outside.
