2000 Massachusetts Ave NW, Washington, DC 20036

The James G. Blaine Mansion stands today as one of the most extraordinary offerings in all of Washington. A rare convergence of historical grandeur, residential elegance, and commercial versatility, it occupies a commanding position at the gateway to Embassy Row. This last-of-its-kind Gilded Age mansion comprises a 7,000-square-foot private residence atop more than 8,000 square feet of income-generating commercial office space — all within a storied structure steeped in provenance. Showcasing a seamless blend of timeless charm and modern functionality, the Mansion was meticulously renovated from 2006 to 2009. Two floors are configured for commercial or office use, two are dedicated to luxurious residential living, and the private rooftop spans the entire fifth level. Beneath it all lies a masterfully integrated, three-story underground garage accommodating 12 parking spaces — a rare amenity in this iconic location. Approaching via the grand porte-cochère over the original cobblestone drive offers a glimpse into the world of James G. Blaine and Washington’s high society of the 19th century. Ascending the stairs and entering through the double doors, one steps directly into history. The first and second floors currently serve as commercial office space, featuring more than 15 private offices, two full commercial kitchens, multiple conference rooms, and two private terraces — offering an unmatched level of flexibility. The residence, occupying the third and fourth floors, is accessed via a private elevator that opens into a double-height reception area. A paneled archway frames a dramatic rotunda, bathed in natural light from the overhead skylight. One of six fireplaces anchors the space, complemented by exquisite millwork — each detail a testament to the vision of noted Washington architect Benjamin A. Van Dusen. Throughout the home, scale and proportion are masterfully executed. A richly appointed library with extensive built-ins, two sunlit dens overlooking Dupont Circle, and embassy-sized formal living and dining rooms create an environment that is both grand and intimate. The chef’s kitchen is warm and functional, centered by a wood-burning fireplace and built-in breakfast nook. Premium appliances from Miele, Sub-Zero, and Wolf are integrated into custom wood cabinetry, set against elegant marble countertops. Whether hosting a 40-person seated dinner or a reception for 150, the residence is designed to accommodate. A secluded private terrace extends from the main level — partially covered for year-round use and featuring an integrated grilling station and tranquil water feature. A temperature-controlled wine cellar adds yet another layer of luxury. The upper residential floor, framed by the original mansard roof, serves as a private sanctuary. The primary suite features vaulted ceilings, dual dressing rooms, and two spa-inspired bathrooms. Additional bedrooms with en-suite baths are complemented by a sunlit office and a fitness room complete with sauna. Above it all, the rooftop level features a private 46-foot lap pool and outdoor kitchen, with sweeping panoramic views over Dupont Circle — a true urban oasis. Yet beneath the refinement lies a core of advanced infrastructure: seven HVAC zones, a comprehensive security system, Sonos sound throughout, and double-pane windows — with triple-pane in the primary suite. The historic Blaine Mansion is more than a home — it is a living monument to Washington’s past and a canvas for its future. Offering unmatched elegance, modern utility, and historical significance, this is a truly once-in-a-lifetime opportunity.
