It would seem to me that a temporary structure like the East Coast Varsity Dome could be erected more quickly and provide more shelter in the short term until a more permanent solution is found. This would provide shelter for high quality tents. There could be an area for meals and meds etc. Perhaps on the selected site a permanent building could be constructed of adequate size for affordable units. 10 storey+. Maybe two buildings?
