The Holy Trinity campus contains a church, a chapel, administrative and pastoral offices, as well as an upper and lower school. In 2009, the church commissioned cox graae + spack architects to complete a concept study to address entrance inaccessibility and space issues, which led to the 2014 renovation of the Lower School, with renovations at the Upper School scheduled to take place the following year. The cox graae + spack plan included the reconfiguration of both school’s entrances, additions to each building, system upgrades and increased accessibility in each facility. The Lower School’s 3-floor addition included a new elevator and accessible restrooms at the east side of the existing structure. The new addition required partial removal of the existing building. The new addition’s exterior walls were constructed of brick with double hung windows to match the existing adjacent walls. The Upper School’s addition on the east side of the existing building included four classrooms and new rooftop mounted mechanical units to support the space.
