Barrack Masters House (Building 3) Hounslow Barracks

The Barrack Master's House, also known as Building 3 at Hounslow Barracks, was constructed around 1876 by Major C.B. Ewart of the Royal Engineers. This two-storey building is made of yellow stock brick with lighter brick detailing, featuring brick external stacks and a slate hipped roof. The house has a double-depth plan and a five-window façade.

The right-hand section of the building is set back and includes multiple bands of lighter brick around the windows, along with bracketed eaves. The central entrance features a rubbed brick round-arched doorway with a radial fanlight and a 20th-century six-panel door. To the left, there is a canted bay with a central tripartite window that has turned mullions and 4/4-pane sashes, with triple 6/6-pane sashes above, including one over the doorway, and additional tripartite windows on the right. The roof extends lower at the rear, featuring a pair of gabled half dormers with paired windows and a doorway located to the right of center.

Historically, the Barrack Master was responsible for the organization of the barracks, and this house is a rare example of a surviving residence for this officer within a barracks. It was added as part of the Cardwell Localisation reorganization of Hounslow Barracks, serving as a significant functional component of the overall site.
