You 'd see people dry heaving before they got on their buses . ' The four-acre site takes up a large part of the town centre , and the council has set up an exclusion zone - and is evacuating 414 nearby homes as a precaution . Northampton Borough Council is live-streaming the demolition of the building , and urged spectators to watch it online rather than in person . The council said the structure is costing taxpayers £500,000 in repairs every year , and it would take almost £30 million to renovate .
