Locating the restroom in the existing small office space minimizes disruption to testing center programming and circulation.

This space is adjacent to the testing area, providing convenient access for testing candidates while maintaining privacy.

Repurposing an existing small room avoids reducing seating capacity or requiring major reconfiguration of the larger testing or hallway areas.

The location is near existing plumbing walls (bathrooms and mechanical rooms in the lower part of the plan), which reduces construction complexity and cost.

This approach aligns with NCARB ARE 5.0 Project Planning & Design content emphasizing efficient space utilization, minimal disruption, and adjacency for functional support spaces in program layouts.
