The post-1896 house served as a children's hospital from 1923 until the 1960s; known first as the "North Staffordshire Cripples' Hospital" and later as the "Biddulph Grange Orthopaedic Hospital" (though it took patients with non-orthopaedic conditions as well. Under this latter title the hospital's role expanded to accommodate adults, continuing in operation into the mid-1980s.) The garden became badly run-down and neglected during this period, and the deeply dug-out terraced area near the house around Dahlia Walk was filled in level to make a big lawn for patients to be wheeled out on in summertime. The Bateman property was (and still is) divided: the hospital got the house and its gardens, and the uncultivated remainder of Biddulph Grange's land became the Biddulph Grange Country Park.
