A 7m wall has gone up on a Sydney beach: are we destroying public space to save private property? – The Guardian
“We really didn’t want to build a wall,” says Bob Orth.
But Orth is one of 10 residents of Collaroy, on Sydney’s northern beaches, who have each paid $300,000 to do just that.
And not just any wall. Construction began in December on a seven-metre-high sheer concrete structure below the residents’ properties, which overlook a beach that has become notorious for dramatic erosion every time there is a big storm.
