Exactly 100 years later, 620 S Allen Ave proves that exquisite design always stands the test of time. This 1925 Spanish Colonial Revival by architect Everett Phillips Babcock has been meticulously renovated over the past three years into something truly spectacular. Blending historic charm with luxurious modern updates, the home invites you to live exceptionally--without compromise. Set in the exclusive Huntington Library District, this stately residence stands proudly among San Marino's finest estates. Inside, graceful archways, exposed beams, and wide plank oak floors frame light-filled, elegant interiors. The sweeping formal living room impresses with a soaring cathedral ceiling, perfect for lively gatherings and evening champagne toasts. Just beyond, the cozy family room and its Gothic arch windows offer the perfect place to unwind. The kitchen is a true showpiece: Italian marble counters, Wolf and Sub-Zero appliances, and custom Italian cabinetry create a space as stylish as it is functional. Enjoy meals in the sunlit dining room overlooking the lush backyard. Five bedrooms include a guest room downstairs and a luxurious upstairs primary suite with spa-like bath and massive walk-in closet. Each additional bedroom has its own en suite for added privacy. Sited on an expansive 3/4 acre lot, the grounds offer wonderful amenities in a private and picturesque setting that feels like your own luxury resort. Invite friends over for a tennis tournament on your pristine, regulation size court, then heat up the built-in grill for a care-free barbecue on the massive wood deck before cooling off with a dip in the saltwater pool/spa. Whether hosting a black tie charity gala or a jubilant summer pool party, you have the perfect venue right in your backyard. The grounds also include a versatile studio, easily used as an exercise space or game room. More than just a legacy home that surrounds you with beauty, 620 S Allen Ave is your invitation to an entirely new world of daily joys for you and those you love most.
