The St. Mark’s School at 25 Marlboro Road in Southborough has completed its new T. Jefferson Coolidge Jr. ’50 Athletic Performance and Wellness Center. Erland Construction and S3 Design worked on the 4,000-square-foot project.

The project gives students double the athletic space with new equipment, recreational space, office space, laundry service for uniforms and even storage space for the school. There are two enclosed walkways, a sprinkler system and new MEP systems surrounding the building as well.

This is Erland Construction’s sixth project with the school.

“Our team felt great satisfaction in repurposing and revitalizing this underutilized space within the circa 1930s field house to create a popular destination for St. Mark’s athletes to train,” Scott Bates, vice present of academic, corporate and commercial group manager of Erland Construction, said in a statement.  “We’re proud to have partnered with S3 Design and St. Mark’s to support the school’s growing athletic and wellness needs and to finish the project on time in three months for the start of the school year.”
