Residents of the Southwest Corridor Annex cherish their “border guard” status which affords them equally convenient access to the big city feel of the Back Bay and the neighborhood charm of the South End. This micro neighborhood is tucked in subtley alongside the origin of its namesake public park, the Southwest Corridor Park – a 4.1 mile greenway, stretching from Back Bay Station all the way out to Jamaica Plain’s Forest Hills station. This linear park features many different activities and facilities along the way and is a terrific commuting corridor for many bicyclists.

The Southwest Corridor Annex has experienced steady appreciation over recent years. To close out 2025, the sub‑neighborhood recorded 8 sales above $2 million, totaling $22,153,000 in volume at an average of $1,356 per square foot. This represented a healthy uptick from 2024, when 7 sales generated $18,431,000, further underscoring the steady demand for premium housing in the area.

Inventory in the Southwest Corridor Annex remains exceptionally tight, with very little opportunity for larger new developments due to the built‑out character of the neighborhood. Instead, turnover tends to occur in older brownstones, which are reimagined through comprehensive gut renovations that elevate historic fabric with contemporary finishes and spatial planning.
