Architecture, Building and Structure Design RO54 Single-Family House by Arshia Mahmoodi Perched on a hilltop in the Bel Air neighborhood of Los Angeles, the project gently lands a dynamic building on top of a buried podium that replicates the original natural topography. The design utilizes an unconventional split-level configuration to follow this topography with staggered floor plates over a central void space. The project was informed by automotive performance design with concealed technologies that amplify the sensory performance of the architecture.
