A non-profit Northern Idaho camp and retreat center that hosts up to 4,000 people annually is spending $1 million to expand with a new three-story building.

The Idaho Business Review reported Tuesday the Ross Point Camp & Conference Center in Post Falls says the facility is being paid for out of donations and savings.

Construction started in November and will likely be completed in April at the 62-acre site along the Spokane River between Coeur d'Alene and Spokane, Wash.

Ross Point is a nonprofit organization that hosts meetings, retreats, conferences, youth camps, and leadership training.

Though associated with the American Baptist Church, it serves religious and non-religious organizations.

It first opened in 1948 and includes 30 buildings in 53,000 square feet divided between cabins, lodges, homes and retreat buildings.
