The Origin of “门当户对”
The term first appeared in the Yuan Dynasty drama The Romance of the Western Chamber by Wang Shifu. In one famous line, it states: "Although we are not equal, it is better than being trapped among thieves." Over time, this idea evolved to symbolize matching social statuses, particularly in the context of marriage.
Interestingly, some believe that “门当” and “户对” originally referred to decorative architectural features on traditional Chinese doors. While not official architectural terms, they became associated with the symbolic objects used to adorn gates and represent social rank.

The Role of "门当" in Architecture
“门当” refers to door knockers, which were integral to the design of traditional Chinese gates. These structures served both functional and decorative purposes. Placed at the base of door frames, door knockers were shaped either like drums or square blocks, often adorned with intricate reliefs depicting auspicious motifs such as:

Over time, drum stones came to symbolize status and achievement. Initially reserved for officials, their use expanded during the Qing Dynasty as the sale of official titles allowed wealthy merchants to incorporate them into their homes.
Understanding "户对"
“户对” refers to door hairpins—wooden or brick carvings placed on door lintels or sides of gates. Beyond their structural role in reinforcing beams, these carvings were highly decorative, featuring auspicious patterns like “Wealth and Peace” or “Good Fortune.”

Architectural Classes of Gates: Dividing Social Status
Gates in traditional Chinese architecture were more than functional—they were symbols of social hierarchy. Doors were broadly categorized into two styles: building-type (independent structures) and wall-type (embedded in walls). Each type reflected the owner’s social rank.
Palace Gates: Reserved for Royals
The highest-ranking gates, such as those in the Prince Gong Mansion, were magnificent structures featuring five-room designs, door nails, and decorative stone lions. A screen wall often faced the gate, adding to its grandeur.

Common Gate Types by Rank
1. Guangliang Gate

2. Jinzhu Gate

3. Manzi Gate
4. Ruyi Gate
The Deeper Connection to "Well-Matched Status"
While “门当户对” is now a metaphor for marital compatibility, its architectural roots emphasize the importance of balance and harmony in design and status. The pairing of decorative elements, such as symmetrical door knockers and hairpins, symbolized equality in status—an idea that carried over into societal expectations.
Today, the physical gates are a testament to history, artistry, and the enduring importance of tradition. Whether in architecture or relationships, being "well-matched" remains a valued principle in culture

Amid rapid urbanization and global climate change, architecture is not only construction but also the art of harmonizing people, the environment, and technology. The Bahrain World Trade Center (BWTC)—the iconic twin towers in Manama, Bahrain—is a vivid testament to this fusion. Completed in 2008, BWTC is not only the tallest building in Bahrain (240 meters) but also the first building in the world to integrate wind turbines into its primary structure, supplying renewable energy to itself [1]. This article explores the BWTC’s structural system and design principles, examining how it overcomes the challenges of a desert environment to become a convincing sustainable model for future cities. Through an academic lens, we will see that BWTC is not merely a building but a declaration of architectural creativity.

As buildings move toward net zero architecture and glare free daylighting, traditional glass façades reveal limitations: high thermal conductivity (~0.9–1.0 W/m·K), susceptibility to glare, and shattering on impact. In this context, transparent wood (TW) is emerging as a multifunctional bio based material: it offers high light transmission yet strong diffusion (high haze) to prevent glare, lower thermal conductivity than glass, and tough, non shattering failure. Recent reviews in Energy & Buildings (2025) and Cellulose (2023) regard TW as a candidate for next generation windows and skylights in energy efficient buildings. [1]

Urban flooding is one of the greatest challenges of the modern era, when sudden and unpredictable rainstorms can paralyze entire cities. Few would imagine that over a thousand years ago, people had already discovered a sustainable solution: the Fushougou drainage system in the ancient city of Ganzhou, Jiangxi. Built during the Northern Song dynasty, this project remains effective to this day, protecting the city from floods—even during historic deluges. The story of Fushougou is not only a testament to ancient engineering but also a valuable reference for today’s cities seeking answers to water and flooding problems.

The construction industry is currently facing immense pressure to reduce carbon emissions, as concrete is not only one of the most widely used materials but also a major source of CO₂ due to its reliance on Portland cement. In response, Shimizu Corporation has conducted extensive research to develop sustainable material solutions aimed at achieving carbon neutrality. One of the most remarkable outcomes is carbon-negative concrete, which partially replaces cement and aggregates with biochar. This biochar is produced from sawdust through a carbonization process and has the unique ability to retain a significant amount of carbon that would otherwise be released into the atmosphere through natural decomposition or combustion. Thanks to this property, carbon-negative concrete not only maintains the necessary mechanical strength for construction but also directly contributes to reducing greenhouse gas emissions. This innovation is considered a promising step that opens new directions for the advancement of green construction in Japan and worldwide.
