A look at the Mass projects that are now lived-in and enjoyed

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.

This residential renovation involved the full transformation of two main bathrooms in a Foxborough home, aiming to modernize the spaces and enhance their everyday functionality.

Revere

A complete transformation, inside and out.
