Naldham House, located on the corner of Mary and Felix Street, is a three storeyed rendered brick building with
basement. The building forms a thin rectangle in plan form with the tower being located at the river end. Redevelopment of the adjacent site has now removed the visual link with the river. The principal
facade is to Mary Street and contains a
colonnade on the ground and first floors. The detailing on the facade is a free adaptation of classical detailing, with ascending orders on succeeding levels. On the first floor there are paired fluted
pilasters without
capitals. The
colonnade at this level has paired
columns with stylised
Ionic capitals. The window openings on the second floor are large and have semi-circular arched heads. Between these openings are paired pilasters with one large
Corinthian capital that extends across the top of both. Above the capitals is a plain
frieze, a
cornice and a
parapet composed of Italianate
balusters. The narrow northern facade has the date "1888" on the upper frieze. The most distinctive feature of the building is the octagonal tower with
cupola at the river end. The cupola, tower end and street facades of the building are intact. The eastern facade, which now contains the main entrance, incorporates classical detail. The date "1988" appears below the cornice. The building has been refurbished internally. The interior including a new staircase was constructed in the manner of a late nineteenth century colonial club. == Heritage listing ==
