181 Fremont is bringing luxury living in San Francisco to a new height with its collection of 55 luxury SOMA condos atop the city's tallest MIXED-USE tower. The building, which has been carefully designed to withstand even the strongest earthquakes, is as beautiful as it is tough. The crown jewel will be its 7,000-square-foot penthouse, a home that is difficult to describe without using superlatives: when it is move-in ready in early 2018, it will be San Francisco's highest and most expensive residence, providing its lucky owner with unbeatable views of the city and the bay from above the clouds.
