Building a Mystery: Nutria House

We’re curious if anyone has any memories of the Nutria House (perhaps officially known to some as the Animal Sciences Lab)  that appears to have existed as part of the Horticulture Center off College Farm Road (Avenue M). There’s mention of it in the Campus Master Plan that was published in 1982 and we’ve come across one photograph of a grayish metal structure labeled "Nutria"; the building looks to be on its last leg and probably was razed shortly thereafter.
