THE COOL FACTOR

Hillside Square complex in downtown Montclair was originally built in 1926 as a Christian Science Church. But, by 2010, the once-flourishing church membership had declined so significantly that the cost of keeping up the property became unaffordable.

“When the church decided to sell the building, they looked for a developer who would care about the building and care about them,” said Paul Sionas, owner of the architectural firm responsible for designing the project. They sold to the Bravitas Group Inc., a Montclair-based developer that specializes in sustainable building practices.
