Ten years later Buffalo voted to become an independent school district.

The school district hired Davenport architect Gustav Hanssen to design a new building.

The T-shaped building had a prominent gable-front entry vestibule and a belfry at the center.

Restrooms flanked the main entrance and a small office for the superintendent was located where the staircase is now situated.

That same year Davenport architect Arthur Ebeling presented plans for the addition of a second story to the school building.

There was no graduating class in 1948 as the three students attended Davenport High School.

A law was passed in Iowa in 1958 that required minimum high school standards.

Another state law was passed in 1966 requiring contingent districts to accept students, so Buffalo became part of the Davenport school district and their students attended Central High School.

They used it as a community center to house various offices and organizations, including the town's library.

Developers Jesse Hammes and Tom Swanwick bought the building in 2010 with plans to convert the structure into a four condo complex.

Eventually, Winsor Consulting of Davenport acquired the building and extensively renovated it for their offices.
