Urban planning in Erith during the Age of the Railway

A developer's plan of the Lesney Estate, east of Erith Railway Station, with recognisable roads including Avenue Road, Park Crescent and Bexley Road (A220). Orientated with north to the bottom of the map, it shows the division of the estate into detached and semi-detached properties, and mark 'The Proposed Site for Lecture Hall, Public Library & Reading Rooms, Market Place, etc'. Along the Thames are Erith Gardens and a 'Proposed Esplanade'.
The map would have been published as part of the prospectus for selling suburban houses to London's middle-class workers who could take advantage of the railways. The map notes that the railway station is '? hour's journey from London'.
