As the population declines and the aging society with a low birthrate progresses, family structures and lifestyles are changing significantly. Nikken Sekkei’s proposal for “Next-Generation Apartment Buildings” is based on the pillars of “diversity,” “sustainability,” and “community.” From units that prioritize privacy to community corridors where residents can interact naturally, and annex units where room size and function can be expanded to suit different life stages, the proposal offers configurations tailored to diverse lifestyles. Furthermore, by incorporating methods to reduce environmental impact—such as the use of renewable materials, natural ventilation, and greenery—the firm presents a prototype for sustainable apartment complexes fit for the next generation.

ZIZAIKU is a movable partition system that allows you to freely reconfigure your floor plan to accommodate changes in your lifestyle or family structure. By combining a wide variety of components—such as panels, sliding doors, curtains, and hanging shelves—that can be freely installed vertically, horizontally, or diagonally without being fixed to thresholds or rails, you can create new living spaces that break free from conventional ideas. A key feature is its high usability, allowing anyone to easily reconfigure the layout. It allows for easy remodeling and changes in usage without the need for large-scale construction, and can be utilized not only in homes but also in common areas, offices, retail spaces, hospitals, and more.

In response to the nationwide issue of “abandoned bamboo groves,” Nikken Sekkei is conducting research on reusing bamboo as a building material to simultaneously address local challenges and reduce environmental impact. Bamboo is a renewable material that excels in strength and elasticity, matures in 3 to 5 years, and—a key feature—can be sustainably utilized without the need for reforestation after harvesting. In 2021, the firm launched the “Bamboo Laminated Timber Structural Model Project” in collaboration with Kagoshima University and others, becoming the first in Japan to obtain a performance evaluation certificate for a bamboo laminated timber structure. The firm is also rolling out the “Let’s Build a House with Bamboo!” project to help the general public experience the potential of bamboo firsthand. At the event, we will showcase our research findings and project examples to date, allowing you to see our efforts to transform neglected bamboo groves into a valuable resource.
