About
Hayashi–Grossschmidt Arhitektuur (HGA) is a Tallinn-based architectural office that designs spatial experiences on various scales – from exhibition designs to urban planning – reflecting the historical, cultural, and social context of the location. The partners are Estonian Hanno Grossschmidt and Japanese Tomomi Hayashi, whose successful collaboration was recognized with the Young Architect Award in 2010.
Currently, they are also working on significant urban development projects: the reconstruction of the Patarei sea fortress, the Hippodrome business quarter development, and the development of the former Luther furniture factory quarter.
