Another residential tower proposed for Allston's GAP

Two developers this week filed plans to further the transformation of Allston's GAP from a warren of student-filled apartments and industrial buildings into a collection of taller residential buildings and towers, with plans for a 322-unit apartment building with a 16-floor wing off Pratt Street, next to the former Conrail train yard.

Houston-based Hines and Framingham-based Calare Properties filed their plans for the 2.2-acre site with the BPDA on Monday. The next day, the Zoning Board of Appeal approved plans by City Realty for a 17-story apartment building a few blocks away on Ashford Street.

The GAP is named for Gardner, Ashford and Pratt streets, the main streets in the now tightly packed area between the train yard - where Harvard plans to build life-sciences labs, offices and residences - Boston University, Packards Corner and Linden Street.

The Hines/Calare project would be next to the 172-unit Allston Green apartment complex planned to replace six current houses on Pratt Street and the hulking building formerly home to the infamous Garage nightclub - which itself would be across the street from a series of new and renovated buildings being developed by City Realty.

The Hines/Calare building would have three wings; the other two wings would be eight and seven stories. Plans call for 48, or 15%, of the units to be rented as affordable.

The plans also call for a garage with 92 parking spaces.

The front of the complex would consist of a driveway off Pratt Street and lawns and a "rain garden" as a buffer to the back of the Allston Green complex.

22-24 Pratt St. filings and meeting schedule.
