Yesterday demo crews began tearing down 2 buildings at Westbury Square, the once-quaint pedestrian shopping district at West Bellfort and Chimney Rock that in recent decades has been overtaken by a combination of bigger-box retailing (see the Home Depot lurking in the background of the photo at left) and neglect. Long-dilapidated Buildings 1 and 5 at 635 Westbury Sq. are being removed under an agreement with the city after a longstanding battle over a “repair or demolish” order, according to the Westbury Area Improvement Corporation. But owner Alfred Antonini still has 9 other 1962-vintage buildings standing on the property, according to appraisal district records.
