90 Johnson Street 

This limestone building at the southwest corner of Johnson and Wellington Streets was constructed in 1851 as a home for James A. Henderson, a barrister and later a judge. The property, designed by William Coverdale, contains what was a large stone residence in the Neoclassical architectural style. It was designated because of its massing and proportions. The character-defining elements of this building include the stone construction, the limestone exterior faced with ashlar and hammer-dressed side walls, the main entrance with semi-elliptical transom, double doors, and flanking pilasters, the wood trim, the flanking bays in wide shallow projections, the second-storey tripartite window above the main entrance, the five segmented arched windows on the front facade with louvered shutters, the two flanking windows on the second storey with small iron balconies, the bracketed cornice, the hip roof and the pair of stone chimneys with small string courses around a moulded lip and decorative chimney pots. The building is also located near St George’s Cathedral.
