Modular School Addition
13,104 ft2 School Addition


When the Notre Dame Preparatory School and Marist Academy opened their elementary school five years ago, it was located five miles away from the Junior High and High School Campus.  With the goal to have all campuses in one location, they purchased an old church and three houses adjacent to their existing high school in hopes to recycle the buildings for their new elementary school location.  In an effort to expand the character of the main campus to the elementary school, they renovated the existing building to include a library, kitchen, cafeteria/gym and offices, demolished two of the houses, and remodeled the third for administrative space. However, despite these changes additional classroom space was still required.

IMS Solution

To create this necessary space, the IMS team built a single story, 13- module addition that was connected to the existing building with an enclosed connector.  The building consists of 12 standard classrooms and one plumbing module.  The interior features 8 ½’ ceilings and 10’ wide corridors.  The building is non-combustible, and is set on a permanent foundation with a crawl space.  The brick exterior and interior wood detailing help the modular elementary addition maintain the character of the high school campus and blend seamlessly with the renovated church building.

The finished building addition also houses an HVAC system that consists of a 95 percent high efficiency gas rooftop mounted condenser with an energy recovery ventilator for each classroom.  The ventilation is monitored by a CO2 sensor that is in every occupied space.  The building also features windows with vandal resistant, low E insulated glass, recessed lockers in the corridor, recyclable carpet tile, low maintenance ceramic tile floors and walls, and low energy electronic ballasts with T-8 bulbs that are controlled by occupancy sensors.  The restrooms include automated plumbing fixtures and hand dryers, as well as washable ceiling tiles.

The modular addition was completed in 139 days and the students were able to attend their new school on the first day of school.
