We are conscious of creating ever-flowing spaces with a story to tell regardless of project type or scale.

 We are an architectural studio founded by Yuichi Kodai (Japan) and Claudia Maggi (UK-Italy) in 2017 in Kyoto, Japan. The studio moved to Zurich, Switzerland, to establish kodai and associates GmbH in 2018.

 Yuichi worked with Herzog & de Meuron in Basel and London for several years before setting up an architectural department with Kohei Nawa in SANDWICH, Kyoto, also known as Creative Platform for Contemporary Art. He finished the award-winning project, Kohtei, in Hiroshima prefecture before establishing the studio with Claudia. He also works at HILDEBRAND Studios.

Claudia worked at Kohn Pederson Fox (KPF) in London for many years and has worked on several large and complex projects, including Herron Tower, once the tallest skyscraper in London. She then established the studio with Yuichi.



We perceive notional connections between spaces through site-specific environmental conditions. Our philosophy is to carefully calibrate requirements and desires to create a timeless and unique space. We propose spaces that one can experience through carefully composed proportions and chosen materials to translate indoor-outdoor relationships. We use our past experiences in architecture, art, and landscape to create a comprehensive experience. 

Our work encompasses a multitude of scales and scopes across Japan, Switzerland, Europe and the UK. The portfolio ranges from residential, commercial, landscape and cultural projects. We work with four key design mindsets:

   1・Working with "the presence of the site." 

   2・Integrating "nature and environment."

   3・Considering "human value and scale." 

   4・Embedding "the power of the material." 


Collaboration is our key Aspect of realizing a successful project.  We work very closely with the client to draw a scheme that can work spatially and functionally. We collaborate alongside craftsmen, masters with special skills, specialists, engineers, and local architects to translate the vision into a reality. We carry out our design services from Zürich to Europe and Asia; working in different countries influences how we approach our work and often results in a cross-cultural product.

The studio holds a broad understanding of the relationship between art and space. Yuichi worked with various creative sectors in Japan, and his experience with Herzog & de Meuron and Kohei Nawa exposed him to a culturally rich and creative environment. We now also work with galleries and private collectors who hold and display masterpiece arts and contemporary arts. We learn the mindset of an artist, their values, and their time as part of the process, which enables us to craft an environment that balances both art and architecture. 



The studio believes landscape and garden are the fascinating aspects to establish an interior and its environment. Yuichi's mind is rooted in Kyoto, where historic temples, shrines, and gardens surrounded him. We develop a landscape and garden scheme to establish an alternative living that becomes part of our way of life. Contemplation, tranquillity, peacefulness, and personal connection to the outside become part of ever-flowing spaces. 


We work with landscaping professionals to achieve inseparable relationships between inside and outside.
