The scope of this project included demolition of existing first-floor office and light manufacturing space to accommodate construction of three sanctuaries, gathering and fellowship areas, a serving kitchen, and a new accessible entrance ramp and deck located at the rear of the building. The Connolly team worked closely with the church’s building committee to expedite delivery of long lead items.

The project involved a change in use from office/light manufacturing to assembly space. This required the addition of two new side entrances and an accessible rear entrance ramp to meet building code provisions for occupancy, life safety, and accessibility.

“It’s been a pleasure working with Boston Onnuri Church,” said Connolly Brothers president and CEO, Jay Connolly. “From planning to completion, our team leveraged their skills to deliver this project successfully. We are honored to have played a role in such an important project and know it will serve the church’s mission for years to come.”
