The 25th Avenue Professional Office Building at 161 W 25th Avenue offers a prime leasing opportunity in a fully renovated, 12,000-square-foot, midcentury low-rise in San Mateo, California. The turnkey suites cater to professional tenants such as law firms, consulting agencies, and tech companies, with tenant allowances available for customized build-outs. Combining the character of 1960s architecture with a modern update by LNAI Architecture, this sleek building has a steel monument frame sporting lightweight aluminum slats coated with a synthetic film to give the look of wood (used as screen shields and a twisting feature above the entryway). A Zen-inspired central courtyard, topped with a gabled skylight, provides a calming focal point for the building. Landscaped with greenery, concrete pavers, and wood benches, the courtyard creates a welcoming indoor-outdoor ambiance. Stairs on each side of the quad lead to second-floor suites overlooking this tranquil space, enhancing the building’s open and airy design. In addition to its aesthetic appeal, the 25th Avenue Professional Office Building offers practical upgrades, including a newly installed HVAC system with individual thermostat controls in each suite, soundproofing for privacy, and enhanced security that secures the building during and after hours. Ample parking is available to tenants and visitors, with two-hour visitor parking in front and 10-hour tenant parking in the rear. The building’s features cater to the needs of modern professionals, supporting productivity, comfort, and security.
