What it is
A 30-storey hotel was assembled in 15 days from steel modules built in a factory and 93% finished, with insulation and clean-air systems built in. It showed that modular prefabrication can reach skyscraper height.
The 15-day speed refers to structure and envelope, not site works or finishes; Broad's marketing exaggerated it, and taller modular buildings have since been built.
What it led to
- high-rise modular construction
- buildings with industrialised insulation and ventilation
- less time and waste on site
