Sheriff Hill
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.
Earth shelter
In some low budget earth shelters, insulation may not be applied to the walls. These methods rely on the U factor or thermal heat storage capacity of the earth itself below the frost layer. These designs are the exception however and risk frost heave damage in colder climates. The theory behind no insulation designs relies on using the thermal mass of the earth to store heat, rather than relying on a heavy masonry or cement inner structures that exist in a typical passive solar house. This is the exception to the rule and cold temperatures may extend down into the earth above the frost line making insulation necessary for higher efficiencies.
