The Vaults Tower is a residential tower project located in central London, defined by a strong emphasis on modularity as a means to support and enhance off-site fabrication strategies. The design is based on a system of vaults conceived as standardized modular units, allowing them to be prefabricated in controlled factory conditions and later assembled on site. This approach significantly minimizes the need for on-site formwork, streamlines the construction process, and reduces construction time. By shifting a large portion of the building process off site, the project also contributes to lower CO₂ emissions, improved efficiency, and a higher and more consistent quality of finishes. Through the integration of modular design principles and sustainable construction methods, the Vaults Tower aims to advance overall building performance while responding to contemporary environmental and urban challenges.
