Nursery School Under Elevated Railway in Machiya

Transforming Urban Infrastructure into Educational Space

The Nursery School Under Elevated Railway in Machiya is an innovative project that repurposes underutilized urban space into a vibrant daycare facility. Addressing the shortage of nursery schools in dense Japanese cities, this project showcases how thoughtful architecture can reconnect communities while providing safe, engaging environments for children.

Historical Context and Site Reuse

Originally built in 1931, the elevated railway supported shops and residences, creating a lively streetscape. After seismic reinforcement, the site remained vacant for years. By introducing the nursery school, the architects revitalized this urban space, reconnecting the neighborhood with its community life.

Design Concept: Open, Protective, and Community-Centric

The nursery school is designed to be open to the town yet protective for children. A 67-meter-long horizontal roof harmonizes the scale of the low (3.9 m) elevated structure with the human scale of the nursery. This roof frames the street-facing facade and shelters interior spaces from the hustle of the station area. It also acts as a light shelf, reflecting natural sunlight into the semi-outdoor playground and activity areas.

Spatial Layout and Features

• Nursery rooms are arranged in three clusters across a central playground and sandpit.
• Semi-outdoor spaces under deep eaves connect rooms and create a visible, engaging street presence.
• Functional areas include washing stations, play equipment, bicycle parking, and entrance porches.
• The 39-meter-long axis under the eaves encourages natural interaction between children and the town.

The design transforms the urban playground into a semi-outdoor environment that is protected from harsh sunlight and rain, while still encouraging community engagement.

Integration with Nature and Community

Deep eaves and seasonal greenery create a sense of security and openness, allowing townspeople to enjoy glimpses of the nursery’s daily life. The street-facing design turns the sidewalk into a living picture scroll, fostering interaction between the nursery and the community.

Sustainability and Urban Reuse

This project exemplifies sustainable urban architecture, turning unused city infrastructure into a functional, child-centric public space. By combining playful design, community engagement, and environmental consideration, it sets a benchmark for future urban daycare projects.
