Located at the heart of Old Town Fairfax, 4235 Chain Bridge Road is a distinguished circa-1900 two-story colonial-style office building offering approximately 3520 square feet of total finished space on a 0.36-acre lot. Originally a private residence, the property has been thoughtfully adapted into a fully operational professional headquarters — most recently serving as the command center for a mid-sized IT firm — while retaining the warmth, character, and intimacy that make it truly one of a kind in the Fairfax City market. The building presents across three functional levels. The main floor features a large open conference room anchored by an original brick fireplace and ceiling-mounted projector, a formal dining area repurposed as a team gathering space, a full kitchen with island and rear exterior access, a reception area, lounge, private office, and two half baths. The second floor is configured as a multi-office suite with six private offices of varying sizes, a full bath, two half baths, and a generous primary suite with walk-in closet — offering an exceptional live-work or executive residency option. The finished basement rounds out the property with a large open workspace, a dedicated server room, a technical room, and access to a rear patio. Throughout, refinished hardwood floors, abundant natural light from oversized double-hung windows, and independently zoned mini-split HVAC systems create a polished, comfortable working environment. On-site parking is available at the rear of the property. This property is ideally suited for the professional user or investor who values location, character, and functional versatility over commodity office space. The intimate, multi-room layout combined with meaningful built-in infrastructure makes it a natural fit across a wide range of users — professional services firms seeking a prestigious Old Town address with private partner-level offices; government contractors and IT firms who will recognize the value of an existing server room and proven technical infrastructure; nonprofits and associations drawn to the civic character and proximity to Fairfax City Hall and the Courthouse; and creative agencies or boutique practices looking for an inspired setting that simply cannot be replicated in new construction.
