Creativity, functionality, sustainability and client-driven design. That’s the foundation upon which Boston architect Matthew Arnold recently unveiled ArnoldAnd, a boutique architectural practice serving residential, commercial and hospitality client in Boston and beyond. Prior to launching ArnoldAnd, Arnold has worked as an architect in the city of Boston and surrounding areas for the past two decades, most notably at Hacin of Boston’s South End. In that time, he earned a reputation for work that masterfully blended modern design and sustainability features within historic homes and buildings—both throughout the city and greater Boston. So much so that when he launched ArnoldAnd at the end of 2024, Modern Luxury Interiors Magazine named Arnold as part of its “Ones to Watch” class of 2025.
