A Back Bay development company this week filed plans to build 211 apartments and 38 condos at 1550 Soldiers Field Rd., near where other residential buildings are already going up.

Dinosaur Capital Partners' proposal, detailed in a filing with the BPDA, calls for 211 market-rate apartments in a six-story building directly on Soldiers Field Road, and 38 condos, all marketed as affordable, in a four-story building on what is now an adjoining lot closer to Birmingham Parkway. The company proposes 202 parking spaces.

The site, now occupied by a two-story office building, is near where the old Black & Decker repair center is now being replaced by an apartment building and the site of a proposed condo replacement for the Lincoln Bar.

And it's not far from the giant New Balance development and its new Boston Landing commuter-rail stop. Dinosaur Capital cites the station, about a 12-minute walk from its proposed buildings, as a reason its proposal is "transit oriented," along with several nearby bus lines.

Dinosaur discusses the basic outline of the proposal:

The Project is conceived as a pair of differently scaled, complimentary buildings, each with a character that respects the neighboring context and the changing nature of the neighborhood. The taller apartment building, overlooking the Charles River, meets the ground with gracious landscape courtyards, and marks the site entry with "rippled" decks at its corners. The affordable condominium building extends a gracious entry and lobby along the quiet cul-de-sac of Soldiers Field Place, and sits to the side of its site allowing generous landscaped gardens and a dog run for resident enjoyment.
