A Fendi collaborator, Hasan, 38, has been working with the fashion house since 2009, when he exhibited at Craft Punk, a Design Miami/Fendi event held during the Salone Internazionale del Mobile in Milan, for which he created versions of his trademark vases alongside boiled leather furniture. This year he will be working on Fendi's Fatto a Mano series, making 20 vases for the label's Selfridges concession, using offcuts of Fendi leather from this season's accessories collection. But Hasan says that recycling isn't his main motivation. 'Sustainable design is important to me as a human being,' but drawing on time-honoured craftsmanship is his true focus. 'I love historical research... looking to the past to keep design alive but in new ways and with new techniques.' He credits designers including Ron Arad, Tom Dixon and Jurgen Bey as influences and admits to finding inspiration in the most unlikely places: 'I have a thing at the moment for construction sites. It's important to have a healthy mix of influence.'
