In less than 29 hours, a Chinese company built a multi-story skyscraper – presumably faster than getting a handyman appointment. The high-speed construction is based on a modular building method. Just like you know from LEGO.
How does skyscraper construction work in under 30 hours? In the Chinese city of Changsha, the BROAD Group has made headlines with a spectacular construction project more than seven years ago: A complete residential building with several floors was erected in less than 30 hours.
Meanwhile, entire building complexes of up to 10 floors can even be completed in the same time (BROAD on YouTube).
The key to this speed lies in a modular building method, where building parts are prefabricated and only assembled on site (Source: Xataka). The principle works like a construction kit: The modules are manufactured in the factory and assembled on the construction site using large cranes (BROAD).
This approach not only minimizes the time required but also typical sources of error in the collaboration of various companies. The individual modules fit precisely together, significantly speeding up the entire process.

Like individual LEGO bricks
What is behind BROAD’s technology? The basis for this process is the so-called Holon system from BROAD. This is an industrially manufactured building system that is delivered completely prefabricated. According to the company, the heart is the so-called B-CORE structure – an extremely robust yet lightweight stainless steel that is corrosion-resistant and ensures a particularly long lifespan (Source: Xataka).
The modules used for Holon Housing already include all essential elements such as electrical systems, air conditioning, and even interior furnishings. In fact, only the modules need to be assembled on-site and connected to utility lines.
China is not only a pioneer in the construction of modular skyscrapers, which offer a potential solution to the growing demand for affordable housing. The country also regularly shows its great ambitions in research: China will introduce the world’s strongest centrifuge with the CHIEF1900 by the end of 2025
