A continental family moves to Los Angeles, leaving tradition behind and embracing a laid-back but luxurious aesthetic.

The pool's clean lines echo those of the house.

The sun-filled open living space is united by a mostly white palette, and the furnishings were chosen as an homage to the era in which the house was built.

In the living area, circular shapes, including a sofa by Modernica, Warren Platner stools, and a chandelier by Gaetano Scolari, play off the angular geometry.

A curtain of shells separates the living area from the dining quarters.

The patio offers a casual spot for alfresco meals.

The music room is decorated with mid-twentieth-century furnishings and toned down with textured materials, such as a Tibetan goatskin rug from Minassian's Paris shop; the 1930s Cubist painting is by Georges Valmier.

A capiz-shell curtain creates a shimmering backdrop in the dining area, which is mostly soft whites and cool grays, including custom-made chairs by Minassian, a circa-1950 cabinet by Edward Wormley, ceramics by local potters from the '50s, and a rice-paper light fixture by artist Stephen White.

The previous owners updated the kitchen, so all the Perrins did was add sleek Bertoia bar stools; family meals often take place at the expansive kitchen counter.

Mosaic tiles line a minimalist bathroom.

The master bedroom features a mix of whimsical elements, such as a metal wall sculpture and a curtain of glass disks; soothing touches, such as translucent silk drapes, provide privacy without obscuring light.

Paper light fixtures by George Nelson illuminate Emma's bedroom.
