4 Kingsbury Avenue, designed by SGA and developed by Alexandria Real Estate, serves as a prominent addition to its campus, anchoring the edge of the new arrival court on Kingsbury Avenue. This 4-story office and research laboratory facility combines modern transparency with historical context, featuring a glass-front façade that fosters visual connections to its surroundings and distinguishes it from the campus's red-brick architecture. The first three floors incorporate intricate brick detailing as a nod to the site's historical structures, while the design aspires to achieve LEED Gold and Fitwel certifications, showcasing its commitment to sustainability and wellness.

Spanning a 29.43-acre site, the building includes approximately 130,000 square feet of total floor area, with a 32,000-square-foot footprint. The construction is classified as Type-IB and accommodates a mix of occupancies, including business, laboratory, GMP manufacturing on Level 1, and amenities such as a café and rooftop deck. The building also features A-2, A-3, B, F-1, S-1, and S-2 occupancies, ensuring a versatile and functional space for its diverse users. By blending cutting-edge design with functional innovation, 4 Kingsbury Avenue sets a new standard for adaptable, sustainable campus structures.
