18 COMMONWEALTH AVENUE
MEET THE TEAM
THE DEVELOPER
18 Commonwealth Avenue is the product of a long-standing partnership between Eagle Hill Capital and Lourenco Carminati, a collaboration rooted in craftsmanship, discretion, and an uncompromising standard of quality. Together, they have delivered a select portfolio of luxury residences across Greater Boston, focusing on properties of architectural significance and lasting value.
Eagle Hill Capital approaches development with a long-term perspective, favoring irreplaceable locations and thoughtful execution over scale. Their work reflects a disciplined philosophy—one defined by restraint, precision, and respect for the historical and cultural context of each asset.
Central to this partnership is Lourenco Carminati, a master builder originally from Brazil whose background in fine construction and artisanal building traditions informs every detail of his work. For almost two decades, he has been responsible for the construction and restoration of high-end homes throughout Greater Boston, known for his meticulous standards, hands-on involvement, and reverence for historic architecture.
At 18 Commonwealth, the partnership’s approach is intentionally understated. The result is a residence where craftsmanship is evident without announcement, modern luxury is delivered without excess, and every detail reflects a commitment to enduring quality.
