Kaleidoscope in Tianshui: A Colorful Kindergarten by SAKO Architects

Located in Tianshui City, Gansu Province, China, the Kaleidoscope in Tianshui is a vibrant non-profit kindergarten designed by SAKO Architects. What makes this project truly unique is its playful and imaginative use of color—specifically, 438 panels of colored glass in ten different hues, which dominate the building’s aesthetic and spatial experience.

These colored glass pieces are carefully positioned above windows and doors, as well as along corridor and stairway railings. It’s believed to be the kindergarten with the most extensive use of colored glass in the world to date.

A Living Canvas of Light and Shadow

During daylight hours, sunlight passes through the multicolored glass panels, casting vivid patterns of light and shadow across classrooms and hallways. These ever-changing effects stimulate children’s creativity, providing a dynamic visual experience that evolves with the sun’s position. As night falls, the building transforms—glowing from within, it projects a luminous and magical presence into the surrounding neighborhood.

Architecture Inspired by Local Traditions

A defining feature of the kindergarten is the use of arched openings throughout the design. This architectural motif draws from the cave dwellings traditionally found in the Loess Plateau, a region that includes Tianshui. To reflect this heritage, the architects incorporated variously sized arched windows placed irregularly across the façades, giving the structure a whimsical and layered appearance—somewhat reminiscent of a celebratory cake.

An Adaptive and Engaging Atrium

At the heart of the building is a multi-purpose atrium encircled by classrooms and activity spaces. This three-story central area is climate-responsive, with underfloor heating and air conditioning ensuring comfort throughout the year. A large glass roof floods the space with daylight, while operable windows help regulate ventilation—open for breezes in summer, sealed tight for warmth in winter.

The atrium’s colored-glass railings wrap around each level, contributing to a stunning display of overlapping hues and shapes. As the sun shifts, the interplay of colored shadows continuously changes—spilling across floors and walls in dazzling arrays. This dynamic environment acts like a massive, slowly turning kaleidoscope, offering children a different experience every moment of the day.

A Space for Play, Learning, and Community

Beyond its visual charm, the kindergarten was designed to suit the region’s cold climate and to foster a sense of community among its young occupants. The atrium allows children of all ages to come together in one shared space, encouraging interaction, cooperation, and a sense of belonging.

The rooftop includes a secure playground area, offering panoramic views of Tianshui. It provides children with a physical and symbolic connection to their city—helping to plant seeds of memory and local pride that may last a lifetime.

An Architectural Symbol of Imagination

SAKO Architects envision this kindergarten not just as a place of education but as a landmark that inspires creativity in every child who walks through its doors. Designed to nurture imagination and togetherness, Kaleidoscope in Tianshui stands as a bright and joyful icon in the urban landscape—celebrated for its innovation, cultural references, and child-focused spirit.
