Christopher and Dominic Leong, brothers and founding partners in the New York–based architectural office Leong Leong, have since 2009 developed a practice shaped by an understanding of architecture as a discipline in constant dialogue with other disciplines, such as art, film, and music. Their installation for this year’s edition of Sight Unseen OFFSITE is no exception: TOPO is an immersive and experiential landscape — created in partnership with ARUP and inspired by the design thinking behind the Ford Edge — that turns a flowing field of more than a thousand foam rollers into a kind of musical instrument, using acoustic actuators to pick up ambient sounds and translate them into a sonic soundscape.
