Approval of federal tax credits will enable a Boston developer to break ground this fall on the latest phase of a housing conversion at a former musical instrument factory in Meriden.

The Connecticut Housing Finance Authority awarded $1.3 million in low-income housing tax credits to Trinity Financial for the adaptive reuse project at the former Aeolian Co. building at 85 Tremont St.

The funding will enable developer Trinity Financial to build 55 apartments, while constructing another 27 mixed-income units simultaneously through a separate financing package.

“By repurposing an historic asset, this development will breathe new life into an underutilized building, remediate a contaminated brownfields site, create more affordable housing for individuals and families at several income levels, and provide easy access to public transit,” Dan Drazen, vice president of development, said in a statement.

The complex was constructed between 1887 and 1920 for the Aeolian Company for manufacturing of organs and player pianos.

The project will include units reserved for households earning from 25 to 80 percent of area median income, along with 11 market-rate apartments.
