Description

No. 21 Dalton Square is a house that has been converted into offices. It was built in the early 19th century and underwent alterations in the late 19th and 20th centuries. The building features sandstone ashlar on the Dalton Square side, while the Gage Street side is made of coursed dressed sandstone with ashlar dressings. It has hipped slate roofs and a narrow rectangular plan located at the corner of Gage Street, which is where the original entrance seems to have been.

The building has three storeys above a cellar, topped with an eaves cornice. Recently, the ground floor on both frontages has been modified by the addition of a shop front, with the entrance located at the corner and a doorway on the left side of the Dalton Square elevation leading to stairs for the upper floors. All windows have plain reveals; the windows facing the Square have altered joinery, while those on Gage Street feature raised surrounds and altered joinery. The central windows on each floor of the Gage Street elevation are formed from a partly-blocked stair-window. The building is included for its group value.
