A former library in Hackney may seem an unlikely venue for London&amp;#8217;s most talked-about new art school. The 1970s Rose Lipman building lacks the architectural wow factor of Central Saint Martins King&amp;#8217;s Cross campus, but demand for places on the postgraduate Open School East in De Beauvoir town is high. The year-long programme boasts visiting lecturers, including the curator of contemporary art and performance at Tate Modern, Catherine Wood, and artists such as Pablo Bronstein and Ed Atkins. The project, which opened in September, is the latest alternative art school to be established in the UK, &nbsp;the&nbsp;students&nbsp;pay no tuition fees.
