SOUTH PORTLAND — Avesta Housing is just about to start building the 64-unit West End Apartments I on Westbrook Street and it’s already lining up funding to add 52 units right next door.

West End Apartments II has been awarded $800,000 in low-income federal housing tax credits, an allocation with an equity value of $7 million toward the estimated $12.5 million project, the Maine State Housing Authority announced Monday.

The rapidly expanding development of the mixed-use, mixed-income housing project validates the city’s decision to rezone the West End neighborhood to promote village-style, pedestrian-friendly development.
