Round Valley performs a neat little magic trick: the house gets bigger when you open the doors. The four-bedroom modern residence isn’t trying to compete with LA’s mega-mansions on interior size. Instead, nearly every room opens toward the surrounding hills and roughly 1,500 square feet of designed outdoor living effectively becomes another wing of the house. That’s where we think the month happens. Breakfast outside. Laptop at the table for an hour. Pool in the afternoon. Dinner under the open sky. The architecture understands Southern California well enough to know that the line between inside and outside is mostly optional. Round Valley doesn’t need another 5,000 square feet of interior because it figured out how to borrow the weather.
