17, 19, 21 and 23, Gideon Walk

17, 19, 21, and 23 Gideon Walk are cottage homes for children, built in 1903 by Leeson for the Newcastle Board of Guardians. They later served as Police Headquarters and a college. The buildings feature cavity walls constructed in stretcher-bond brick, with some areas pebbledashed and painted, and they have Welsh slate roofs. Designed in the Domestic Revival style, the two pairs of semi-detached houses are deliberately asymmetrical.

The former Block 9-10 consists of two storeys and six bays. The doorway to No. 9 has a cornice above it, while No. 10 features a semicircular hood. No. 9 includes a canted bay window, and No. 10 has a standard bay window. The windows are two- and three-light designs set in moulded wood surrounds. There are cross gables over the first and third bays, with a gabled half-dormer over the fourth bay, and the fifth and sixth bays are under one large cross gable. The roof is hipped and has three brick-corniced stacks.

The former Block 11-12 has nine bays. The doorways have semicircular hoods supported by brackets; No. 11 features a large bay window above its entrance, while No. 12 has a round-headed window. The central two bays contain tripartite windows in moulded wood surrounds, with semicircular pediments above the first-floor windows. To the left, there are three bays with 12-pane sash windows and a dentilled string at the first floor. To the right, there is a canted bay window. Above the central bays, there are two Flemish gables. The roof is hipped on the left with an octagonal lateral shaft and gabled on the right with an end stack.

These buildings are a notable example of the progressive approach to child care in the early 20th century.
