A leading union will today call for 250,000 new houses to be built every year and for 30,000 empty homes to be brought into use to tackle the UK's housing "crisis".
The GMB believes workers are being priced out of buying or renting a house because of rising costs.
Housing is the biggest issue on the agenda of the union's annual conference in Nottingham, where delegates will today demand action.
A special report by the union's executive will call on an incoming Labour government to make affordable housing a central part of its economic and social strategy.
The conference will debate calls for the compulsory acquisition of empty homes and regulation of the private renting sector.
Millions of people find their rent or mortgage a constant struggle or are falling behind with their payments, the union believes.
The report by the GMB executive said for the last 30 years the number of new households needing accommodation has been growing at nearly twice the rate of new dwellings becoming available.
