Former Drill Hall front buildings

The former drill hall front building is constructed from grey limestone and features a slate roof. It consists of two buildings that are separated by an archway. Above the archway, there is corbelling at the eaves level and a prominent rock-faced stone top with a square stone plaque that bears the Prince of Wales feathers and the inscription 'Pembrokeshire Territorial Force Drill Hall'. The arch itself is a high round shape, made with cut stone voussoirs and a large keystone. There are double iron gates adorned with some scrollwork on the top rails.

The two flanking buildings are two storeys high and have two bays each. They feature large windows with cambered heads, cut stone voussoirs, and stone sills. Each inner bay has a single window above an arched doorway, while each outer bay has paired windows under broad cambered heads on both floors. The windows have small panes in the upper sashes only. The doorways include recessed blind tympana and late 20th-century doors, with stone voussoirs and keystones.

The inner end walls and rear walls are painted roughcast, and there are brick square chimneys on the rear roofs just behind the ridges. The rear windows also have cambered heads and small panes in the upper sashes only. The rear of the arch is stuccoed.
