A modern mid-century house in the Los Feliz neighborhood of the Hollywood Hills, this was an extensive renovation. The house was brought down to its studs, new foundations poured, and many walls and rooms relocated and resized. The aim was to improve the flow through the house, to make if feel more open and light, and connected to the outside, both literally through a new stair leading to exterior sliding doors, and through new windows along the back that open up to canyon views. photos by Undine Prohl
