New Price! Situated on a tree-lined street in a prestigious estate neighborhood adjacent to Caltech and the renowned Huntington Library Gardens, this stately 1909 English Tudor revival was home to preeminent architect, John C Austin, for almost four decades. Originally sited at 85 S Madison, Austin moved the existing house to its present half-acre knoll on Arden Road in 1925 to make way for the expansion of Green Street. Best known for designing iconic landmarks like the Griffith Observatory, LA City Hall, the Shrine Auditorium & Hollywood Masonic Temple, Austin masterfully expanded this home and encased the old structure in a new outer concrete shell. Grand in scale and proportion, this well-crafted 6096sf residence features an outstanding floorplan with high ceilings, gracious public rooms, five fireplaces, 6BRs, a finished 1303sf attic, a 671sf basement, plus a 527sf chauffer's quarters adjacent to a garage and motorcourt. A major 2007 remodel modernized all major house systems, kitchen and bathrooms, and resulted in this magnificent family home that's perfect for today's lifestyle. The private backyard, with its covered patio and expansive lawn, lends itself for both intimate or grand-scale entertaining and outdoor enjoyment. Just a stone's throw from South Lake shops, markets & restaurants, Polytechnic School, the Langham Huntington Hotel, and with easy access to all major freeways, this exceptional home is an architectural treasure in a most coveted neighborhood.
