This led to the building of the first council housing estate in Gateshead. Alderman Hodkin laid the foundation stone on 27 October 1920; as work commenced the Alderman demonstrated the authority's concerns, telling the local newspaper that: "we can build houses, but we cannot build homes. Only the people themselves can do that and I hope that the spirit of ‘esprit de corps’ will prevail and this will be a model estate" Demand was highthere were 427 applicants for the first twenty eight houses builtand the council built further tracts of housing in a broad triangle between Sodhouse Bank, Ermine Crescent and The Avenue, although central government withdrew its promised funding. By 1936, most of the social housing available as of 2012 was in existence and provides accommodation to over half of the population of the suburb.

A main consideration regarding timber piles is that they should be protected from rotting above groundwater level. Timber will last for a long time below the groundwater level. For timber to rot, two elements are needed: water and oxygen. Below the groundwater level, dissolved oxygen is lacking even though there is ample water. Hence, timber tends to last for a long time below groundwater level. In 1648, the Royal Palace of Amsterdam was constructed on 13659 timber piles that still survive today since they were below groundwater level. Timber that is to be used above the water table can be protected from decay and insects by numerous forms of wood preservation using pressure treatment (alkaline copper quaternary (ACQ), chromated copper arsenate (CCA), creosote, etc.).
