The nice old house and outbuildings at 208 Montauk Highway in Amagansett had been for sale for quite a while with no buyer emerging when the owner approached East Hampton Town Hall for help. The result is a hearing at East Hampton Town Hall tonight on a zone change that just might hasten a closing. But the request, to go from a residential designation with a limited-business overlay within the Amagansett Historic District to full-on commercial, should be rejected.
