Renovating and expanding large-scale buildings requires expert architectural vision combined with practical construction expertise. In this project, FLWB led the full design-build effort to revitalize an outdated office structure: reimagining the facade for better energy efficiency and aesthetic presence, upgrading mechanical/electrical/plumbing systems throughout, optimizing floor plates for flexible workspaces, and adding new levels while preserving structural integrity. From early programming and 3D modeling to material selection, contractor coordination, and phased on-site execution, our unified team ensured minimal disruption to occupants and maximum value. The transformed building now offers enhanced daylighting, improved indoor environmental quality, and LEED-aligned features—illustrating FLWB's capability to architecturally redesign entire commercial properties for long-term performance and appeal.
