Architecture Workshop is an ideas-driven practice based in Wellington with a variety of architecture, landscape and urban architecture projects around New Zealand. AW was established by Christopher Kelly on his return to New Zealand from Europe in 1991, following six years studying and then working with architects that included Denys Lasdun and Ian Ritchie. In particular Kelly has been influenced by his ongoing working relationship with one of the world's leading architects, Italian Renzo Piano, and established his own practice as a 'workshop' to reflect the focus on process and construction which he admires in Piano's approach. From 1998-2000 AW collaborated with Renzo Piano and Bovis Lend Lease on a A$500 million design build multi-storey office tower and apartments in Sydney, Australia.
