XX-LAM explores the spatial and structural possibilities of curved, cross-laminated timber construction. It adopts the “cross lamination” bonding pattern of CLT as a conceptual strategy for exploring the language of mass-timber architecture. XX-Lam applies (crosses) the technical capabilities of CLT with the architectural principles of the John Hejduk’s Nine Square Grid exercise in an installation of curved, linear components set within at 3X3 architectural grid at Omaha by Design.
