Whitley Rooms (Building Number 1/138) and Bollard at North East Corner

The Whitley Rooms, also known as Ivy Lane Cottage, is a dockyard gatehouse that has been converted into an office. It was built in 1857 at HM Naval Base on Victoria Road. The building is constructed of red brick in English bond, featuring ashlar and replacement concrete dressings, with gauged red-brick arches above the openings. It has a concealed hipped slate roof with a rendered stack.

The exterior of the building is two storeys high, with two bays on the west elevation and four on the east elevation. It has a plinth, round-arched openings with an impost band on the ground floor, and flat-arched windows with replacement 12-pane sashes and a sill band on the first floor. The eaves are stepped and dentilled below a cornice with a blocking course. The north elevation contains blind windows and a door on the left, while the south elevation has a blocked original flat-arched doorway on the left with a blind window above it. The west elevation features a door on the left and an inserted door between the right-hand windows. At the north-east corner, there is a cannon barrel, likely from the early to mid-19th century, which has been reused as a bollard, probably set in place in the mid to late 19th century.

Inside, there are two blocked tall round archways in the spine wall, along with a closed-string staircase that has stick balusters and bulbous columnar newels. Originally, there were cells along the west side of the building. It is adjacent to the dockyard wall and served as a gatehouse to Marlborough Gate until the gateway was relocated to the south.
