Northeastern University is going ahead with the ?expansion of its south campus with plans for a mixed-used student dormitory on Burke Street, between Columbus Avenue and Tremont Street.

The university and Austin, Texas-based American Campus Communities plan to redevelop an approximately 23,424-square-foot parking lot into a 310,000-square-foot building with some 800 beds in apartment-style units on the upper floors, student amenities and services, and ground-floor commercial space.

Northeastern plans to ground-lease the site at 10 Burke St. to American Campus — the nation’s largest developer, owner and manager of student housing communities — which would build the dorm, the university said in a letter of intent filed with the Boston Redevelopment Authority.

Northeastern said it would file more detailed project plans and an amended master plan with the BRA in early January.

The project will contribute to the pattern of residential infill that Northeastern has undertaken in recent years on the Roxbury side of its campus, anchored by International Village at the end of Columbus Avenue, according to the university’s master plan, which had envisioned the Burke Street dorm apartments accommodating 300 to 350 beds. Future improvements include a potential new and/or improved MBTA crossing at Camden Street and the west end of the Massachusetts Avenue station platform.

Streets surrounding the Burke Street student housing proposal would benefit from landscaping tied to the project, including sidewalk improvements and tree-plantings, and increased ?pedestrian use, the university said. The dorm would have its principle entrances on Burke and Coventry streets, and Columbus Avenue.
