Thick Concrete Exteriors of This Library on a Reservoir Pond Make It Earthquake-Resistant | Maru Architecture | Matsubara| Japan

Japanese design firm- Maru Architecture has restored the central library of Matsubara in Osaka Pefecture, by incorporating a monolithic extension hovering on a peaceful pond. Situated within the reservoir, the library extension contains large openings to allow enough daylight and air to enter so that the readers enjoy quiet moments of privacy, reading, and learning. Surrounding by large burial mounds and moats, the building which is named the ‘forest of reading’ looks like a burial mound itself. Designed on a historical Japanese tumulus, the library uses a structural system with a 600mm reinforced concrete outer wall, which is 3 times thicker than what is normally used and an inner steel floor framing. The project also gained 2020 Good Design Award along with 2020 Osaka Environmentally Friendly Architecture Award. Read more details below at SURFACES REPORTER (SR):

Proper Ventilation

The library extension has large openings that allow air to circulate freely in the structure. Apart from this, the surrounding water body also contributes to natural ventilation through an evaporative cooling effect.

Major Challenge

The biggest concern for the MARU Architecture on the water was cracking of the exterior wall due to the drying shrinkage.

Japanese design firmTo overcome this challenge, the practice adopted a crack control steel bar technique, inducing fissures at the crack-inducing hings to stop wall-surface rifts from being further generated in other sections.
