With a major renovation/expansion completed in 2003 by Lorcan O'Herlihy, FAIA and extensive remodeling by Robert Steloff Design in the last decade, this warm rectilinear Architectural masterpiece evokes the spirit of historic modernist architect Mies van der Rohe and is the trophy property of the road. Stunningly secluded from the street and approached by a lush garden pathway, this home will envelop you in its casual elegance featuring light hardwood floors, an abundance of natural light, walls of glass, skylights, and extensive built-ins. Upon entering the home, a Great Room welcomes you to relax along with being an incredibly flexible entertaining space which opens to a custom Boffi kitchen with top appliances and stainless-steel clad counters. The large dining area opens through a huge distinctive glass pivot-door to the substantial walled entertainment courtyard with Ipe wood decking, built-in seating, fireplace, BBQ center, and direct access to the 2 car garage. From the Great Room, one descends a gentle 7-step glass-walled bridge with a central succulent garden atrium view leading to two glass-walled bedroom suites and an open lounge/office area which then ascends via a striking floating metal staircase to the independently-set superlative 2nd story "treehouse style" primary suite highlighted by a kitchenette, sitting area, glass walls, spa-style garden-view bath, and mammoth dressing room/walk-in closet space. Below the bedroom structure and accessed via the central outdoor atrium is a private rear destination "secret garden". Generous off-street parking in addition to the 2 car garage is a welcome front-facing feature. This is a true treasure in the heart of Brentwood and moments to the finest amenities of the Westside.
