Create a series of variations and iterations of an axonometric architectural massing model. The model should include three primary components: 1. Residential Building: In tradition Hong Kong ‘Old Slab’ Architectural style. Represented in white, this structure should be designed with varying heights and forms. Explore different configurations such as stepped, terraced, and linear arrangements. 2. Podium: A base structure that supports the residential building, shown in grey. Experiment with different sizes, shapes, and integration methods with the residential units. 3. Commercial Center: Depicted in brown, this area should be designed with various layouts, including open plazas, enclosed spaces, and mixed-use areas. Test different arrangements, such as street-front retail and internal atriums. Ensure that the variations maintain a consistent scale and style, focusing on modern architectural aesthetics. Use clean lines and minimalistic detailing in the models. Present the designs in an axonometric view to clearly showcase the spatial relationships and massing.
