Both the home designed by Neutra (right) and the contemporary main house (left) sit in stunningly green surroundings in Pacific Palisades, California.
Neutra's 2,000-square-foot 1948 home was one of 34 designed as part of the Case Study House Program. Today, only 21 of the original homes remain standing.
At the time, Neutra built the residence for Stuart and Lucia Bailey, creating a clean and crisp living room that includes floor-to-ceiling glass.
According to the New York Times, glass became the focus of his design, as he used the largest sheets he could find to create a 1,200-pound sliding-glass door leading to the terrace.
Mahogany features were used in the dining room to create a warm and inviting space for meals.
Floor-to-ceiling glass offering spectacular views of the garden were also put into the bedrooms.
The residence's original design included two bedrooms, but as the Bailey family grew, Neutra designed additional bedrooms that were connected to the main house through a walkway.
Simon's primary home is adjacent to the property.
Inside is a large glass sculpture by American glass sculptor Dale Chihuly. It hangs elegantly in the entrance.
Built in 2010, the contemporary home includes ceilings that reach as high as 25 feet in certain areas.
In total, there are five bedrooms, complete with beautiful glass windows that let in sunshine and surround the space with nature.
There are also nine sleek bathrooms, some of which are designed with stone and wooden features.
The backyard includes a beautiful cascading infinity pool. It sits between the two homes.
There is also a stone Jacuzzi nestled in the garden.
Over the years, Simon engaged master architects and restoration artists to preserve Neutra's design. Today, the estate is set on magnificent private grounds that offer full privacy for its residents.
