Terrain Architects

What Terrain Architects does

Terrain Architects is a privately held architecture studio founded in Tokyo in 2011 by Ikko Kobayashi and Fumi Kashimura. The firm provides architectural design and supervision services across residential houses (renovations and new construction), educational facilities (nurseries, primary schools, dormitories), and commercial projects (restaurants, cafes, shops), operating from a Tokyo headquarters at 1-16-14-4F Shinjuku, Shinjuku-ku and a secondary office in Kampala, Uganda. The studio's core philosophy treats site constraints as positive design elements — viewing terrain, climate, culture, and local materials as integral characteristics to amplify rather than overcome. Notable completed projects include the AU dormitory (1,316 sqm, Uganda, 2015), Yamasen Japanese Restaurant (785 sqm, Uganda, 2018), TERAKOYA primary school (269 sqm, Uganda, 2020), Kashimada Nursery (1,219 sqm, Kawasaki, 2022), and the Endang Bunko library (64 sqm, Indonesia, 2011).

The business operates as a traditional professional services firm with project-based, quote-based fees; pricing is not publicly disclosed. Revenue is generated through direct client engagement and referrals, with award-driven PR and academic partnerships substituting for paid marketing. The firm maintains deep ties to Tokyo University of the Arts (both founders are alumni; Kashimura is Associate Professor) and has expanded its East African academic network to Makerere University, Uganda Martyrs University, and Kyambogo University, supporting ongoing workshop programs sponsored by the Kenjiro Otsuka Foundation and The North Green School. The practice is registered as a first-class architect office in Tokyo (Registration No. 60744) and as a corporate member of the Uganda Society of Architects (CORP/390), with structural engineering supported by long-term partner TECTONICA.

The firm has accumulated 12 documented awards between 2012 and 2024, anchored by the 2020 Good Design Gold Award (with METI Minister's Award) for Yamasen, the 2019 Aga Khan Award for Architecture shortlist for AU dormitory, the 2023 Good Design Best 100 and JIA Award for Kashimada Nursery, and the 2024 Golden Pin Design Award Best Design. Staffing is 1-10 employees as of the most recent disclosure, with active recruitment for Tokyo-based design staff in 2024. There is no external institutional investment, parent company, or public listing.
