Developer AvalonBay Communities Inc. wants to start construction next year on a 38-story apartment tower next to the TD Garden that would include a two-story retail arcade connecting to the Garden and North Station.
The development would bring 503 apartments to the city’s West End, where several developers are seeking to move forward with large housing and retail projects. AvalonBay outlined new details of its plan in a filing released Tuesday by the Boston Redevelopment Authority, which must approve the project before construction can begin.
A rendering in the filing shows a multi-tiered glass and stone tower that would rise on air rights above an MBTA parking garage off Nashua Street. Eventually, the apartments — ranging in size from studios to three-bedroom units — could be sold as condominiums. The building is being designed by CBT Architects of Boston.
AvalonBay’s proposal significantly increases the number of residences from a prior proposal that called for 363 apartments. That plan, by the Boston Garden Development Corp., was approved in 2006, but failed to move forward in the declining economy.
AvalonBay’s plan does not increase the height of the tower, which was previously approved at a height of 460 feet. But it does significantly redesign the project, incorporating new elements such as the two-story retail arcade.
If approved, the arcade will run between the Garden and the Tip O’Neill Federal Building, providing pedestrian connections to North Station and Causeway Street. It will also connect to Nashua Street, where the developer is proposing to build a small park on an empty lot owned by the MBTA.
“The arcade will be able to accommodate large-scale pedestrian traffic and is lined with retail and amenity spaces creating a lively and vibrant atmosphere both at game time as well as at commuting times,’’ AvalonBay wrote in its filing. “During TD Garden events, the arcade and associated retail operable storefronts will function not only as a prime circulation route, but also as a gathering space for pre-event activities.’’
Tenants for the retail spaces will not be announced for several months. AvalonBay said it wants to start construction by the fall of next year.
