About Speaker

unknown works is an award winning design studio based in London and Hong Kong. The studio’s work spans the fields of architecture, urban design, immersive events, exhibition design, installation art, graphics and digital media. 

​They work at all scales; from the creation of cultural and commercial buildings, residential projects, urban design and infrastructure projects to multi-media performances and immersive interventions. We apply architectural thinking to fields beyond, exploring bold ideas through critical research using writing, exhibitions, film and illustration.

​Unknown Works are fascinated by the human condition, the development of cities, the interactions of social and urban environments and the mechanics of space distribution. From inception to completion, our goal is to uncover the hidden potentials of a projects brief and context in order to arrive at a solution that is architecturally refined, when required disruptive, and always progressive. We strive to benefit people and places through stimulating projects that have a positive lasting impact.
