Christie's International Real Estate SoCal's Cindy Ambuehl and Luca Diamont have sold 371 20th Street, a 2018 five-bedroom designer home north of Montana Avenue with interiors by Natasha Baradaran, for $7.95 million in October 2026.
Cindy Ambuehl and Luca Diamont of Christie's International Real Estate SoCal have closed the sale of 371 20th Street in Santa Monica for $7,950,000. The sale closed in October 2026.
The house sits north of Montana Avenue, in one of Santa Monica's most sought-after neighborhoods, a few minutes from the Brentwood Country Mart, the shops and restaurants of Montana Avenue, and the beach. Built in 2018, it is a designer residence of more than 5,000 square feet with five bedrooms and six bathrooms, finished with interiors by Natasha Baradaran.
A gated entry opens to a lush front courtyard with mature trees and landscaping that recalls the English countryside. Inside, a dramatic two-story entry leads to a formal living room with a fireplace and an elegant dining room with a wine closet. The main floor also has a private office and an en suite bedroom.
The kitchen is the heart of the house, with Wolf and Miele appliances, a large eat-in island, a butler's pantry and a breakfast area whose accordion doors open to the yard. Next to it, a family room with a stone fireplace and disappearing glass doors runs straight out to a covered patio with a gas fireplace, a built-in barbecue, a generous lawn and tall, mature hedges.
Upstairs, the primary suite has a vaulted ceiling, a fireplace, a private balcony with treetop views, and a bath with a soaking tub and glass shower. The guest suites share the floor with a second living area and the laundry room, and custom built-ins, skylights and high beamed ceilings bring in character and natural light throughout.
Ambuehl is an Executive Director at Christie's International Real Estate SoCal, where she leads the Cindy Ambuehl Group from the firm's Brentwood office on San Vicente Boulevard. Diamont, a Los Angeles native and former Duke University quarterback, is a luxury estates agent on her team who works across Brentwood, Santa Monica, the Palisades and Malibu.
