Tsukuigaoka Kindergarten: A Community-Centric Design by Naf Architect & Design

Located in the Tsukui district of Sagamihara City, Tsukuigaoka Kindergarten has been an integral part of the community since its establishment in 1979. Designed by Naf Architect & Design, the newly built kindergarten addresses modern educational needs while preserving its historical and social significance.

A Landmark in Sagamihara’s Educational Landscape

Set atop a scenic hill, Tsukuigaoka Kindergarten has nurtured generations of children, fostering strong community ties. The previous structure, having undergone multiple renovations over the decades, faced aging-related issues, prompting the decision to construct a future-oriented facility that enhances accessibility, sustainability, and spatial efficiency.

With Sagamihara’s declining birthrate and changing demographics, the new design strategically accommodates evolving societal needs. A long driveway, inspired by a rest stop, improves transportation access, allowing shuttle buses to pick up and drop off children efficiently. This multi-purpose front yard also serves as an adaptable space for outdoor events, social gatherings, and even mobile kitchens.

Architectural Vision: Honoring the Past, Embracing the Future

The symbolic roofline, inspired by the original triangular roofs of the previous building, is a defining architectural feature. Designed to be a recognizable landmark, the upward-curving roof enhances visibility from major roads leading to Lake Miyagase, a popular recreational area. This thoughtful integration ensures that the kindergarten remains a visible and memorable part of the landscape.

The new structure consists of two primary buildings:

• The Hall Building, designated for music and cultural activities such as drumming and flute practice, fosters creativity while serving as a rentable community space for external events.
• The Classroom Building, featuring four nursery rooms, maintains continuity with the original kindergarten layout. An expansion space—a wide corridor adjacent to the classrooms—enables flexibility for larger gatherings, aligning with certified childcare center standards.

Natural Materials and Child-Centric Design

Emphasizing sustainability and durability, the design incorporates locally sourced cedar paneling for the exterior walls. The facade treatment varies—horizontal siding below waist height allows for easy repainting, while vertical siding above minimizes maintenance.

Interior elements prioritize child-friendly design:

• Textured flooring and distinct wall finishes for different age groups create a visually stimulating environment.
• Loft spaces offer playful, engaging nooks for children.
• Strategic glazing balances openness with privacy, using frosted glass at child height to reduce distractions while maintaining clear sightlines above.

Fostering Community Engagement Through Architecture

With over 8,000 graduates and a connected network exceeding 20,000 individuals, Tsukuigaoka Kindergarten is more than an educational facility—it is a cultural cornerstone. Events such as flea markets and sports festivals draw participants from across the region, reinforcing lifelong connections to the institution. Many alumni return as parents or even as educators, continuing the cycle of community engagement.

A Model for the Future of Educational Architecture

By blending historical continuity with modern adaptability, Tsukuigaoka Kindergarten sets a precedent for educational architecture in Japan. Its flexible spatial planning, sustainable material choices, and deep-rooted community integration ensure that it remains a dynamic, engaging environment for future generations.
