In 2015, Southtree Commercial completed a 24,500 sq ft, two-story building for the Southside Church Newnan Campus. In 2018, the Southtree team assisted with a 20,000 sq ft expansion to the Newnan Campus that included a new entry under a tower and a new state-of-the-art worship center. In addition to the expansion, 12 acres of the property were improved with two new detention ponds with one pond having 16 foot tall poured concrete walls, and the interior of the existing facility was renovated. The building was designed by Jefferson Browne Architecture, Inc.
