This April edition is Blueprint's Materials issue, and it's packed full of them — from the aluminium fins of Rand Elliott Architects' Oklahoma Contemporary (our cover star) to the world's first timber stadium by Zaha Hadid Architects. We report from Copenhagen where practices such as Lendager Group are championing upcycled building materials, visit a house made of hempcrete from Practice Architecture and Material Cultures, and explore the rise of biomaterials like mycelium and seaweed plastic. In Listen, Peter Clegg urges architects to prioritise consideration of embodied carbon in material usage. Meanwhile, editor Johnny Tucker sits down for an exclusive interview with master of materials Tom Dixon.

Elsewhere in the issue, we meet the co-curators of this year's British Pavilion at the Venice Architecture Biennale, Madeleine Kessler and Manijeh Verghese of Unscene Architecture, and take a look at thre rise of the global industry — and culture — of sneakers, including an exclusive interview with adidas creative director Paul Gaudio. Plus: Ben Adams Architects, imm cologne, Maison&Objet, Page\Park Architects, Proctor & Matthew Architects, Rem Koolhaas and much more.
