Working class housing spread rapidly and without control throughout the Victorian era, particularly in the Hawkhill, Blackness Road, Dens Road and Hilltown areas. Despite the comparative wealth of Victorian Dundee as a whole, living standards for the working classes were very poor. A general lack of town planning coupled with the influx of labour during the expansion of the jute industry resulted in insanitary, squalid and cramped housing for much of the population. While gradual improvements and slum clearance began in the late 19th century, the building of the groundbreaking Logie housing estate marked the beginning of Dundee's expansion through the building of planned housing estates, under the vision of city architect James Thomson, whose legacy also includes the housing estate of Craigiebank and the beginnings of an improved transport infrastructure by planning the Kingsway bypass.
