LU Houses
LU HOUSES
LU Houses is an urban densification residential project developed under a Townhouse or Type A Condominium typology. Located on a 400 m² site in Providencia, the project comprises two single-family homes of 140 m² each, offering an alternative approach to living in established neighborhoods through the use of industrialized mass timber construction systems.
The project was conceived around a structural strategy that integrates glued laminated timber (GLT) beams and columns with 90 mm cross-laminated timber (CLT) floor panels, optimizing the balance between structural performance, construction efficiency, and indoor comfort.
Structural System
The structural solution consists of a hybrid system combining GLT elements and CLT panels, leveraging the structural capabilities of both technologies to meet the project’s architectural and functional requirements.
GLT beams and columns form the primary structural framework, while the 90 mm CLT floor panels act as industrialized load-bearing elements, providing stiffness, dimensional stability, and rapid installation. This configuration reduces the overall self-weight of the structure compared to traditional construction systems while optimizing building processes within a consolidated urban environment.

Manufacturing and Assembly
The use of prefabricated mass timber components enabled a significant portion of the production process to be carried out off-site, ensuring high levels of dimensional accuracy and quality control during manufacturing.
The industrialized system significantly reduced on-site assembly times and minimized the disruptions typically associated with conventional construction methods. In addition, the reduction of wet trades contributed to a more efficient and controlled construction process, particularly relevant within a densely developed residential setting.
Performance and Sustainability
One of the project’s primary objectives was to incorporate a construction solution capable of improving the thermal performance of the homes, enhancing indoor comfort and energy efficiency throughout their service life.
The use of mass timber also helped reduce impacts associated with the construction process by minimizing waste generation, airborne dust, and noise pollution during installation. These characteristics make GLT and CLT systems particularly well suited for urban densification projects in established city environments.
LU Houses demonstrates the potential of mass timber to address contemporary urban housing challenges by combining industrialization, construction efficiency, technical performance, and reduced environmental impact.
