A tower in five days<\/h2>\n\n\n\n
The building, developed by Broad Group Holon, covers about 150,700 square feet and contains 26 floors of housing. China Daily reported that the apartments were built for people hired through a local talent introduction program, with residents getting the first two years rent-free.<\/p>\n\n\n\n
Each floor includes eight apartments of about 732 square feet, along with four elevators. This means the tower is not a display shell or a stunt structure. It is housing, and it was designed to be occupied.<\/p>\n\n\n\n
The most surprising part is how little of the work happened outdoors. The building site became less like a traditional construction zone and more like a final assembly line, with modules lifted into place by cranes and bolted together.<\/p>\n\n\n\n Each apartment module was prefabricated in a factory before being transported to the site. The units measured roughly 39 feet long, 9.8 feet high, and 7.9 feet wide, with wiring and ductwork already installed before they arrived.<\/p>\n\n\n\n That changes the rhythm of construction. Instead of waiting for concrete to cure, trades to rotate, and weather to interrupt every stage, much of the job moves indoors where production can be more controlled.<\/p>\n\n\n\n Jeremy Zimman<\/a>, Director of Marketing for Holon Modular Building Systems at BROAD USA, described the installation method as \u201cpick and place, stack, bolt, connect utilities.\u201d He also told the Modular Building Institute that BROAD has streamlined production so one module can be completed every 21 minutes.<\/p>\n\n\n\n The core of the system is BROAD\u2019s B-CORE technology<\/a>, a stainless-steel sandwich structure used instead of conventional reinforced concrete. The Modular Building Institute describes B-CORE as two stainless-steel plates with stainless-steel tubes fused between them.<\/p>\n\n\n\n The company says it chose stainless steel not only because it resists corrosion, but because it has ductility. In simple terms, it can bend under stress rather than cracking suddenly, an important feature in earthquake-prone regions.<\/p>\n\n\n\n Broad Group Holon has also claimed the tower could last more than 1,000 years. That number should be treated as a company projection, not an independently proven fact, but the idea behind it is clear enough. A longer-lasting structure could reduce the need for repeated demolition and rebuilding.<\/p>\n\n\n\n The environmental stakes are not small. The latest Global Status Report for Buildings and Construction<\/em><\/a> says the sector accounts for around 37% of global CO\u2082 emissions and nearly 50% of global material extraction. That is why any construction method promising less waste and better efficiency deserves a closer look.<\/p>\n\n\n\n Broad\u2019s system also focuses on the way residents live inside the building. China Daily<\/em> reported that the apartments have insulated exterior walls, four-pane windows designed to block solar heat, and features that could reduce air-conditioning costs by as much as 90%. For anyone who has watched the electric bill climb during sticky summer heat, that part matters.<\/p>\n\n\n\n Still, there is nuance here. Stainless steel can be durable and recyclable, but steel production itself can be carbon-intensive, and the building sector remains heavily dependent on materials such as cement and steel. The sustainability case depends on full life-cycle data, not just a fast construction video.<\/p>\n\n\n\n These modules were not empty metal boxes. BROAD USA says it completed the Jingdu tower turnkey, with water, electricity, air conditioning, and energy-recovery ventilation<\/a> already included.<\/p>\n\n\n\n Zimman said the only missing items were movable appliances such as refrigerators, washers, dryers, dishwashers, and microwaves. That is a very different image from the usual months of interior finishing after a structure is topped out.<\/p>\n\n\n\n A New Zealand modular-building specialist, Tony Frost, stayed in an 11-story Holon building in Changsha and told China Dail<\/em>y that it felt \u201csturdy, almost like a concrete structure.\u201d He also praised the water filtration system, while noting that interior colors and textures could still be improved.<\/p>\n\n\n\n One of the strangest claims is also one of the most interesting. Because the tower is bolted together, the company says it can be dismantled, transported, and rebuilt somewhere else if needed.<\/p>\n\n\n\n That could matter for cities facing floods, land-use changes, or fast-shifting housing demand. A building that can move is not just a building anymore. It becomes something closer to long-term infrastructure with a second life.<\/p>\n\n\n\n Since the Jingdu project, BROAD has continued pushing the Holon system abroad. In 2026, BROAD USA said a 16-story modular residential tower in Abu Dhabi<\/a> used the same volumetric modular approach, with modules manufactured in 30 days and installed on site in 96 hours.<\/p>\n\n\n\n The Jingdu Holon Building does not mean every city can suddenly build high-rises in less than a week. Local codes, fire safety rules, inspections, financing, factory capacity, labor training, and transportation limits all shape what is possible.<\/p>\n\n\n\n However, it does show that construction can look very different from the noisy, dusty, traffic-snarling projects most people know. At the end of the day, the real lesson is not just speed. It is that more of the building process may move from the street to the factory floor.<\/p>\n\n\n\n That shift could help cities build faster and waste less, but only if independent testing, transparent carbon accounting, and strong safety rules keep pace. The tower is a glimpse of the future, not the whole future.<\/p>\n\n\n\n The official statement was published on BROAD USA<\/a>\u2019s<\/em> website.<\/p>\n","protected":false},"excerpt":{"rendered":" No concrete was poured.
