Nestled on a picturesque tree-lined street in one of San Marino's most sought-after neighborhoods, this beautifully maintained home is just a short walk from San Marino High School. Thoughtfully updated over the years with guidance from Pasadena Showcase House 2025 interior design advisors Jennifer Bevan and Samantha Williams, the residence showcases hardwood floors, elegant crown molding, and refined designer touches. The concrete/clay roof was installed in 2018. The front door opens to a grand living room with soaring open-beam ceilings and a majestic fireplace. The recently renovated formal dining room is an entertainer's dream, featuring hand-crafted millwork and large paned windows. The spacious kitchen features a large center island, golden oak granite countertops, travertine flooring, coffered ceilings, and a charming breakfast nook. An inviting den opens to the scenic backyard surrounded by mature trees. The first floor also includes a private guest bedroom with an en suite bathroom. Upstairs are three additional bedrooms, including a spacious primary suite with an en suite bathroom that has a double vanity, soaking tub, and separate shower. A second bedroom features a built-in bookshelf and balcony, while the oversized third bedroom offers two generous closets. An additional bathroom is conveniently situated between the secondary bedrooms. The backyard is a private retreat highlighted by lush foliage, a stunning black-bottom pool, and patio spaces ideal for barbecuing and outdoor entertaining. Recent upgrades include lighting and electrical improvements, plumbing upgrades, window treatments, enhanced security and fire alarm systems, and earthquake bolting. A refinished approximately 146 sq. ft. bonus room adjacent to the garage, not included in the home's official square footage, provides flexible use as a gym or workspace.
