In the face of climate change threats, Japanese architect Takayuki Ushijima took on the challenge of designing a structure that could withstand the risks of flooding. Located in the city of Maibara, Shiga Prefecture, the "U-House" demonstrates Ushijima's professional insights into disaster prevention and response. Combining wood and concrete, this building is carefully crafted to address local flood concerns and prepare for the potential impacts of rising sea levels.
Design Inspired by Flood Prevention and Traditional Architecture
The "U-House" is situated in a region that was once part of Lake Biwa, and over the years, has transformed into a residential area due to post-war land reclamation and industrial changes. Given the risk of future flooding caused by rising sea levels, Ushijima focused on flood prevention in his design. The two-story home draws inspiration from traditional elevated "kuran" structures, incorporating a concrete foundation at the base to elevate the building, creating a distinct separation between the house and the ground.
Elevated Structure and Open Spaces
The ground floor features a recessed interior space with an open undercroft that serves as a wide, sheltered corridor. Large movable glass windows offer views of the intersection between the concrete floors and the wooden framework, providing transparency and bringing nature into the indoor courtyard. The design incorporates ample greenery, making the space not only a place to live but a sanctuary of natural beauty.
Functional Living Spaces Above
A wooden staircase leads to the second floor, which contains the main living areas, including the kitchen, dining room, living room, bedroom, and bathroom. Ushijima carefully consolidated all the essential living functions on the second floor to minimize the impact of potential flooding on the ground floor. The interior design transitions from the dark exterior tones to light, airy hues, with wooden floors complementing the wooden structure and metal accents creating a sleek, cozy atmosphere.
Sustainability and Environmental Considerations
Despite common misconceptions, wooden construction techniques are increasingly effective and well-suited for various climates and usage habits. European, American, and Japanese wooden building technologies have evolved significantly, offering solutions to many potential challenges. The construction of U-House also prioritizes environmental sustainability, using green materials and eco-friendly paints to minimize the impact on the environment. In addition to ensuring a healthy living environment, these choices contribute to the broader goal of sustainable development.
