Full demolition and construction of a modern penthouse

Located in the heart of East Boston, Princeton St stands as one of MASS’s flagship projects – defined by its bold transformation, architectural quality, and attention to detail.

The project involved the structural demolition of the original third floor and the creation of an entirely new level: a contemporary penthouse designed from the ground up.

Key highlights include:

• Complete third-floor teardown, enabling a fresh and creative architectural approach
• Construction of a light-filled, minimalist penthouse with open spaces, high ceilings, and expansive windows
• High-end interior finishes, smart spatial planning, and a clean, functional design language
• Integration of a private terrace with open views, connecting indoor living with the outdoors
• Warm-toned woodwork, a neutral color palette, and refined lines that reinforce a sense of urban elegance

Princeton St is more than a renovation, it’s a statement of what we do best: crafting spaces where design, function, and precision come together.
