When architect Antonio Monserrat transformed an old 800-square-foot Brooklyn loft into his new home, he imbued his love of colorful, multifunctional design into an eye-catching renovation. Once used as a bakery in the early 20th century, the postindustrial space came with great bones—original exposed timber beams, 12-foot ceilings and large windows—that Monserrat used as a backdrop for his playful color choices, small-scale studio prototypes, and contemporary furnishings. From the emerald-green entryway with a hot-pink ceiling to the sunshine-yellow Kartell storage pieces, the Spanish architect’s loft beautifully blends creative inspiration with functionality.
