Go Hasegawa earned a Master of Engineering degree from the Tokyo Institute of Technology in 2002 and worked at Taira Nishizawa Architects before establishing Go Hasegawa & Associates in 2005. He quickly completed a series of notable projects, paying great attention to detail and proportion. His approach is both contemporary and deeply rooted in Japanese tradition. Each project is an intensive inquiry on our perception of space, gravity, and time. Hasegawa challenges pre-existing ideas on largeness/smallness, heaviness/lightness, and newness/oldness, seeking values not previously recognized.
 
Go Hasegawa is the recipient of numerous awards, including the 2008 Shinkenchiku Prize and selection as one of the ten 2014 AR Design Vanguard architects. He designed a long list of residential projects in Japan, including: House in a Forest (2006), Pilotis in a Forest (2010), House in Kyodo (2011), Yoshino Cedar House (2016), Roof on a Ridge and Villa beside a Lake (both 2020). Non-residential architecture includes the Nippon Design Center in Ginza (2012) and the Chapel in Guastalla (Italy, 2017) a circular marble structure, the inner side of which is a continuous ring of benches set in niches carved so thin that the stone lets in light. In 2019 Hasegawa completed flying carpet, a ribbon-like elevated walkway made of steel water pipes in the garden of Luis Barragán’s house-studio in Mexico City.
 
Several monographs about Go Hasegawa’s work have been published by TOTO, a+u and El Croquis.
