Having spent years crafting this remarkable estate, Tavangarian spared no expense in its creation. The property initially came together through an $11 million land purchase in 2018, with Tavangarian expanding the estate over time. Although the construction faced minor delays during the pandemic, it was finally completed in 2023. In his quest for perfection, Tavangarian decided to wait until every detail, including the custom furnishings, was finalized before listing Villa Siena on the market.

Over the past decade, Tavangarian has developed some of the most sought-after properties in Los Angeles, earning a reputation for pushing the boundaries of residential design. His recent project, Villa Siena, is a testament to his vision, incorporating advanced technology and luxurious materials, making it one of the most ambitious estates in Bel-Air. With an eye for perfection, Tavangarian continues to shape the luxury real estate landscape, setting new benchmarks for architectural excellence.
