Wethersfield High School originally opened in 1952, with several small renovations taking place in 1957, 1970, and 1993.

The current school building standing on the property is a multi-story brick modern-style structure.

By the 2010s the school did not meet current educational curriculum requirements, did not address current safety standards, and was not code compliant for individuals with disabilities.

[6] The aging building was evaluated and a referendum was passed for a "Renovate As New" construction plan.

The renovation started in October 2013 with a planned completion date of April 2017.
