Based in Tokyo and founded in 2001 by Seimei Takeda, the Takeda Seimei Architectural Design Office is renowned for blending traditional Japanese aesthetics with modern architecture. Rooted in the principles of "ma" (間)—the concept of space and interval—the firm's designs emphasize harmony between structures and their natural surroundings.

Notable projects include the Yama-no-oto House in Kyoto, which skillfully uses wood, stone, and glass, and the Sora Community Center in Osaka, known for its sustainable design and open-plan layout. The firm won the prestigious Good Design Award in 2018 for the Shizuku Pavilion, a temporary structure designed for a cultural festival.

Continuing to innovate, Takeda Seimei Architectural Design Office focuses on revitalizing urban spaces with green technologies and community-centered design, remaining a beacon of thoughtful and enduring architecture.
