Housing We Should Build For The Homeless

I read a news report about a mother with two children in the USA living in a storage unit.
In India whole families live in garages and open the door during the day and sit on the pavement in front. it seems to me that in addition to building three bedroom family homes with gardens, Uk councils and the equivalents worldwide should build cheap bedsit dwellings with a bed, a windows, a washbasin and a microwave for the homeless or temporarily homeless who need and address to get a job and claim benefits. A larger unit with a bunkbed and cot or two bunkbeds could temporarily house families. It could be built on cheap land out of town on a bus route or with a shuttle bus into town driven by volunteers or by the residents on a rota.
