Behind the gates of Saint Laurent - one of Newport Coast's most intimate enclaves at just 66 homes - 25 Lyon offers three bedrooms plus a flex bonus room that converts naturally into a fourth bedroom. A gated courtyard with a cascading waterfall announces your arrival, opening to a wraparound yard anchored by fruit trees, an in-ground spa with its own waterfall feature, and a Twin Eagles BBQ island built for the effortless entertaining that defines coastal California living. Inside, the architecture rewards the eye at every turn: custom millwork with wainscoting, cased windows, and crown molding throughout; solid walnut hardwood flooring that runs room to room; and a family room framed by custom built-in cabinetry that flows directly into a chef's kitchen finished with white cabinetry, Carrara marble countertops, warming drawer, a butcher block island, farmhouse sink, breakfast banquette, and a full Thermador suite - six-burner cooktop with griddle, double oven, and more. The second level offers a primary suite with vaulted ceilings, a walk-in closet, dual vanities, soaking tub, and separate shower. The over-sized bonus room can be perfect home office, teen room or bedroom number 4. More practical upgrades - PEX piping, an epoxy-floored finished garage with built-ins, and in-ceiling audio throughout. Take in the coastal breeze with walks to the community pool, Newport Coast Elementary, dining, shopping, parks, and hiking trails, with Crystal Cove State Beach just minutes away. 25 Lyon is an opportunity not to be missed.
