After 1959 the building was adapted and converted into a residence for the senior RAEME Officer and by the late 1960s it had been adapted again as married quarters. This function was maintained until 1982, when the building was converted into a multi-denomination chapel and re-named All Saints Chapel. The former School of Musketry is designed in the Federation Free style of architecture. It is a single story red brick structure with a galvanised iron hipped gable roof with a pedimented entry and ventilated gable. The roof extends to cover a concrete paved verandah which surrounds two thirds of the front wing of the building, the former lecture room. The most striking external feature is a decorative ventilator fleche with a conical cap, placed at the apex of the roof, which is connected to ventilation grilles in each of the main rooms of the building. The building is laid out in a symmetrical plan, with a main central lecture hall, and two wings to the left and right, leaving a small built-in courtyard to the rear. The left hand wing was designed for offices, including a pay office, whilst the right wing was for the armoury and rifle racks. The architecture of the building presents a strong response to climatic considerations of the sub tropics. Each of the main rooms was designed with a door that would open to the outside, while the roof and verandah provides shade to most rooms. The building's function has changed several times during its life to date, necessitating some changes, but most of the permanent changes have been minor, while significant changes have been substantially reversed since the conversion from married quarters to chapel in 1982. The main changes occurred during the adaptation from stores building to residence. Internal studded partitions were installed, especially in the lecture hall area, to create a number of bedrooms. In addition, the rear courtyard became enclosed and a kitchen and laundry installed to the rear. The conversion to All Saints chapel, however, has reversed much of this, with the internal partitions removed. The kitchen remains and the laundry has been converted to toilets. Many of the original doors and door furniture, fanlights, double-hung sash windows and architraves are intact. The building is in very sound condition. Externally there have been some modifications to fenestration, and internally alterations were carried out in 1960s to convert to married quarters including new bathroom, kitchen, and toilet. However, the original fabric is substantially intact. The former School of Musketry, Gallipoli Barracks, Enoggera, is significant as one of the two oldest substantial buildings at the former Enoggera Army Base.
