Three buildings on the beach in the Black Sea city of Bourgas were demolished by the city hall on May 25 2009 for failing to conform to legal requirements, private national bTV channel said.Construction on the three buildings was underway when the city hall despatched demolition machines, bTV said. According to the Black Sea Act, buildings built for commercial purposes that have lifeguards, medical assistance posts or public toilets within their confines cannot cover more than one per cent of the beach, a stipulation the three buildings failed to abide by.The three buildings were also demolished because they failed to meet the requirements of the so-called "removable places". This stipulates that the only sections of newly-built structures along the Bourgas Black Sea beach that can have roofs are kitchen areas. These requirements aim to replace the solid concrete buildings currently existing on the beach by light constructions that are easily removeable at the end of the season.The demolition did not go down well with the beach concessionaire who, according to bTV, said that the plans for the buildings had been approved by the Regional Development and Public Works Ministry. He said that he would file a claim against the city hall, bTV said.
