Zero Marlborough, a highly coveted corner of Marlborough and Arlington Streets, is Back Bay's most exclusive and coveted luxury condominium address. The historic building, originally constructed in 1929-1930 and famously known as the former Katharine Gibbs School, was the beneficiary of a comprehensive, award-winning gut-renovation in 2008. The conversion preserved the building's pre-war architectural splendor while integrating the best in modern-day luxury standards, for which it won a Preservation Award in 2009.

This is a ultra-luxury building by intention, with only 13 opulent residences dispersed over its eleven floors. This small number ensures exclusivity and close-knit living situation, often more reminiscent of an individual Manhattan-style apartment than a multi-building entity. The residences are surprisingly generous, measuring up to more than 4,600 square feet in some cases, and many are set up as full-floor residences with direct elevator access, ensuring privacy and dramatic views from all sides of the building.

Residences at Zero Marlborough are defined by superior craftsmanship and top-of-the-line finishes. Residences boast high ceilings, hardwood floors, and walls of glass that frame stunning views beautifully. Most coveted overlooks look directly out over Boston's Public Garden and Back Bay skyline. Kitchens are a chef's delight, complete with professional stainless steel appliances (e.g., Sub-Zero and Wolf) and stone countertops. Primary suites feature lavish, multi-component marble bathrooms and large walk-in closets. In addition to that, most residences feature fireplaces and private outdoor rooms.

As a prime luxury building, Zero Marlborough offers full-service conveniences for easy city living. They include 24-hour doorman and concierge services, private fitness center, and, a critical amenity in the Back Bay, valet garage parking.

The address places residents in a tranquil park-side setting, yet mere steps from the vibrant energy of the city. High-end shopping, dining, and art galleries on Newbury and Boylston Streets, and Beacon Hill's classic heritage, are all within walking distance, making Zero Marlborough a trophy asset at the confluence of Boston's most desirable neighborhoods.
