St. Luke’s is building on its promise to improve the health of communities across Idaho through its Boise Campus Development project that began a year and a half ago. Since breaking ground in 2024, the organization is making headway and achieving significant milestones.
At a Glance:
- St. Luke’s Boise campus expansion broke ground in 2024 with completion expected by 2030.
- The project will add 80 patient beds, seven new operating rooms, and advanced neurological diagnostic equipment.
- Layton Construction manages the multi-phase project, coordinating construction on the active hospital campus.

The new tower and medical office plaza, located just north of the existing hospital along Jefferson Street between Avenue B and 1st Street, will have 860,000 square feet of patient-centered care which includes 80 additional patient beds, seven new operating rooms, and two neurointerventional biplanes for innovative diagnosis of neurological disorders. The project also allows for some growth, where areas will be shelled and left unfinished and then built out as further demand and funding allow…
