The Old Registry Building is a well preserved example of an original administrative building and Classical Vernacular Style.

This property was originally purchased by Edward Jessup. It was sold in 1858 to the Municipal Council of the United Counties of Leeds and Grenville.

The stone building is an interesting example of vernacular architecture. The walls are plastered and there is some rock-faced stone on the front façade used for decoration. This also highlights a large pediment, which tends to give the building a somewhat formal, classic look.

The front room has a false ceiling at about 9 foot height. Above this, near the front door, original plaster cornice moulding of ornamental outline is still intact. It likely continues in other portions of the room, which are not as visible. The small original stone building was enlarged, and later a two-storey brick addition was built at the rear. 

The exterior of the main building of the Old Registry Office (excluding the porch) as well as the decorative cornice moulding at the ceiling in the front or south room is designated.
