A magnificent Greek Revival brownstone on Boston's prestigious Beacon Hill has returned to the luxury real estate market with a $15.5 million asking price after sitting vacant for more than two decades. The historic property at 94 Mount Vernon Street, which fronts the exclusive Louisburg Square and backs onto the iconic cobblestone Acorn Street, represents one of Boston's most coveted addresses where location alone serves as shorthand for elegant urban living.

The five-story residence was originally built in the 1830s by Boston's 19th-century upper class as part of the Greek Revival architectural movement that defined much of Beacon Hill's character. Like many single-family mansions in the area, the property was eventually converted into multi-family housing as the fortunes of Beacon Hill and the Back Bay fluctuated over the decades. By the turn of the 21st century, the building had fallen into severe disrepair, forcing tenants to abandon the once-magnificent structure.

"When we bought it in 2024, it was very decrepit," explained Gaetano Morello, principal of High Street Development, a real estate firm specializing in the restoration of historic brownstones throughout Back Bay, the South End, and Beacon Hill. The property's deteriorated condition required a complete interior overhaul while maintaining strict adherence to historic preservation standards required for buildings in Boston's protected historic districts.

The restoration project faced unique challenges due to the building's conversion history. "Because it had been converted to multi-family housing a long time ago, there were no original details left," Morello noted. "But we still had the ceiling heights, the brick walls, the original window openings and the front door surround. Inside, it is once again a single-family home, but everything is brand new." The development team made the strategic decision to strip the interior completely and rebuild it with modern amenities while preserving the building's historic 1830s architectural integrity on the exterior.

The renovated mansion now encompasses over 7,000 square feet of luxurious living space across its five stories, making it unusually spacious even by Beacon Hill standards. The property features six bedrooms, five full bathrooms, and three half bathrooms, providing ample accommodation for large families or frequent entertaining. Four gas fireplaces are strategically placed throughout the home, adding both warmth and traditional charm to the modern interior spaces.

The gourmet kitchen serves as a centerpiece of modern luxury, equipped with a premium Lacanche range and other top-of-the-line appliances that cater to serious home chefs. The floor-through primary suite offers unprecedented privacy and space, while the entire home benefits from the high ceilings and large windows characteristic of Greek Revival architecture. Perhaps most valuable of all Boston amenities, the property includes access to a nearby garage parking space, addressing one of the city's most persistent urban challenges.

Outdoor living space represents another major selling point for this urban oasis. The property features multiple outdoor areas designed to maximize the limited space available in dense Beacon Hill. A deck extends from the kitchen at the rear of the house, while a spacious walled garden opens directly onto historic Acorn Street, one of Boston's most photographed cobblestone lanes. The crown jewel of the outdoor spaces is a private rooftop deck that provides panoramic views of downtown Boston, the Charles River, Boston Common, and the Back Bay neighborhood.

The rooftop deck required special engineering to comply with historic district regulations. Because the house sits within a designated historic district, the roof deck was constructed to remain completely invisible from street level, ensuring that the building's historic streetscape appearance remains unchanged. The exterior restoration involved meticulous attention to period details, including repointed masonry work, installation of new granite lintels, and complete slate roof replacement, all designed to replicate the building's original 1830s appearance.

"Today, the house honors the historic tradition of Beacon Hill, but the interior is super modern," Morello emphasized, summarizing the project's dual commitment to preservation and contemporary luxury. The successful restoration represents a significant investment in one of Boston's most prestigious neighborhoods, where properties rarely come to market and command premium prices when they do. The $15.5 million listing reflects both the property's prime location and the extensive renovation work required to transform a derelict structure into a world-class urban residence.
