The Hong Lok House, a recently redeveloped low-income housing residence for Chinatown seniors, was recently completed.

The $37-million project features 74 new units, replacing the former 28-unit elder housing facility built in 1978.

The building was redeveloped through donor support and has incorporated a “green roof” and tai chi deck, along with other improvements to promote an active and healthy lifestyle.

The facility meets the U.S. green building council’s LEED Silver standard with many energy efficient features.

The project began in April 2006 when the Greater Boston Chinese Golden Age Center hired Rogerson Communities to redevelop the existing Hong Lok House, an outdated HUD-202 residence for low-income elders. Developers broke ground in August 2011 after some delay in gathering finances.

Rogerson Communities fundraised, secured the financing, designed and built the new eight-story facility.

“It was a privilege to have worked with Rogerson Communities to bring this project to fruition. The end product is something the entire community can be proud of and I am pleased to be welcoming each tenant into their new home,” Ruth Moy, executive director of Greater Boston Chinese Golden Age Center, said in a statement.
