<![CDATA[General Background: Digital visualization of architectural designs has become an essential requirement in the modern real estate and housing development industry to communicate spatial concepts effectively. Specific Background: Creating three-dimensional models of residential cluster units requires a systematic technical approach based on two-dimensional architectural drawings and specific building materials. Knowledge Gap: Prior studies predominantly focus on final rendering or single-building modeling without addressing the specific methodological workflows required for repetitive cluster housing units utilizing affordable software. Aims: This study aims to describe the technical implementation of SketchUp software in compiling three-dimensional layouts for residential cluster housing units based on two-dimensional design data. Results: The application successfully produced detailed three-dimensional models of two housing variants, achieving accurate spatial conversion from 2D floor plans while overcoming geometric and detailing challenges through phased modeling techniques. Novelty: This research establishes a practical workflow for converting 2D architectural data into structured 3D models tailored for uniform and repetitive residential cluster developments. Implications: The implemented modeling approach provides a reliable reference for engineering students and practitioners to generate informative visual representations for design analysis and presentation. Key Findings Highlights SketchUp effectively converts two-dimensional architectural floor plans into detailed three-dimensional residential models with minimal dimensional deviation. Modular modeling strategies and component reuse reduce modeling time for repetitive cluster housing units by up to forty percent. Establishing custom material libraries according to technical specifications significantly enhances the visual realism and informational value of the model.
