The property comprises an imposing and substantial bank building with a sizeable two-storey extension and small, fully-enclosed yard to the rear. The property has been extensively refurbished in recent years and is laid out to provide banking hall and offices on the ground floor, ancillary office at first floor level and storage space in loft-style accommodation on the top floor. Access to the upper floors is through a common entrance lobby.

The property is located on the northern side of Dominick Street at the junction with Mary Street and fronting onto Bank Square. The building enjoys a prominent location in the main financial services area of Mullingar town, to the west of the main retail area of Pearse Street and Oliver Plunkett Street.

The property is a highly appealing and extensively detailed two-storey Italianate Palazzo-style Victorian bank building. The late nineteenth-century construction (c. 1874) retains its early form and character. This building was designed for the Bank of Ireland by the noted mid-to-late nineteenth century architect Sandham Symes (1807-1894), architect of choice of the Bank of Ireland from c.1845 until c.1880, and reflects the typical architectural style favoured by Symes.
