Crosslam Completes Brazil's Tallest Mass-Timber Tower
The Aurora 275 project demonstrates the viability of industrial timber construction in Brazil.
1Record-Breaking Hybrid Structure
Engineering firm Crosslam has completed Aurora 275 in the Suzano area of São Paulo, Brazil. Standing 22 meters tall, the structure is officially recognized as the country's tallest hybrid mass-timber building. It utilizes a reinforced concrete core combined with metal and engineered timber elements to achieve its unique architectural height and form.
2Strategic Market Demonstration
Founder José Alberto Corrêa initiated the project to prove the feasibility of timber construction to the skeptical Brazilian market. By acting as both designer and builder, the company aimed to build trust among local developers. This internal project serves as a tangible proof-of-concept for the potential of mass-timber in industrial housing.
3Rapid Assembly Process
The construction of Aurora 275 was completed in just four weeks by a specialized team of five people. This rapid timeline highlights the efficiency of industrializing construction through engineered timber components. The materials were sourced locally and produced in Crosslam's own factory, ensuring precise control over the building's structural assembly.
4Structural Design Details
The building features a concrete core with timber elements extending in two directions, supporting 10 individual apartments. While the exterior is primarily metal-clad with yellow accents, the interior exposes cross-laminated timber floorplates and glulam beams. This design choice provides a warm aesthetic while showcasing the structural integrity of the wood.
5Environmental and Performance Benefits
Crosslam claims the building is carbon neutral, aligning with global trends toward sustainable construction practices. The use of engineered timber offers significant advantages, including reduced waste on-site, dimensional precision, and a lighter overall structure. These factors contribute to improved building performance compared to traditional concrete-heavy methods used in the region.
6Industrial Housing Potential
The project serves as a model for industrial-style housing production across Brazil. By demonstrating that timber can be used effectively for taller structures, Crosslam hopes to shift local construction norms. The company emphasizes that the assembly process is not only faster but also more efficient than conventional methods currently dominating the market.
7Global Context of Timber
Mass-timber construction is currently gaining significant momentum in North America and Europe as a sustainable alternative to steel and concrete. While Brazil has been slower to adopt these methods, the completion of Aurora 275 mirrors international efforts to scale timber usage. Australia recently topped out the world's tallest timber structure.
8Future Industry Implications
The success of Aurora 275 suggests a potential shift in Brazilian construction practices toward more sustainable, industrialized solutions. As Crosslam continues to advocate for timber, the industry will monitor whether this project leads to wider adoption. The focus remains on balancing structural performance with the environmental benefits of using renewable materials.
