NEIGHBORHOODS
Golden Triangle
Overview
The Golden Triangle represents another premier Boston sub neighborhood. Other than forming a perfect geometric shape (it does not!), the Golden Triangle rarely disappoints its residents.
Location
This sub-neighborhood runs from Columbus Avenue, the South End/Back Bay borderline, to Tremont Street, the spine of the South End. In between are a handful of fantastic streets that support no shortage of high end homes. While picturesque Appleton Street arguably holds the most prestige, Chandler, Montgomery, Clarendon and Warren Avenue are not far behind. Plus, the smallest streets, Lawrence and Gray, add some intrigue to this sub- neighborhood.

Landmark Sales Set the Tone
The top sale of 2025 was a single-family residence at 155 Warren Avenue, which closed at $6,100,000 after originally being offered at $6,999,000. This was followed by 505 Tremont Street, Unit 905, which traded for $5,250,000, further cementing The Atelier at 505 Tremont as a cornerstone of the sub-neighborhood. One of the South End’s few full-service residential buildings—offering a doorman, concierge, and elevator service outside of Ink Block—Atelier 505 has consistently attracted top-tier buyers since its construction in 2005. In 2025 alone, the building closed three sales above $2M, continuing its dominance after also securing the neighborhood’s top sale in 2024 at $4,900,000, or $2,114.80 per square foot.
$2M+ LUXURY MARKET DATA
In 2025, the Golden Triangle emerged as one of the South End’s strongest performing sub-markets. The neighborhood recorded 19 sales totaling $65,679,000, with an average price of $1,457.94 per square foot, accounting for 18.16% of all South End sales volume for the year. While transaction count moderated from 24 sales in 2024, total dollar volume remained resilient, down modestly from $76,957,400, and pricing continued to trend upward from $1,421 per square foot in 2024. Historical context reinforces the neighborhood’s durability, with $48.9M in sales in 2023 and $70.7M in 2022, underscoring consistent long-term demand even amid shifting market conditions.
