UNDER CONTRACT OPEN HOUSE CANCELLED Don't blink. Tucked at the end of a quiet cul-de-sac in one of Pasadena's most desirable neighborhoods, 1405 Saybrooke Court delivers the kind of space, setting, and flexibility that is nearly impossible to find. Surrounded by tree-lined streets and beautiful Colonial homes on expansive lots, this property sits on over an acre of level, usable land designed for the way people actually live-inside and out. From the moment you arrive, the full front wrap around porch and manicured landscaping set the tone, welcoming you into a grand two-story foyer with hardwood floors and classic trim details including crown molding, chair rail, and shadowboxing that carry throughout the main level. Formal living and dining rooms offer timeless elegance, while the heart of the home-a massive, fully upgraded kitchen with new granite countertops, top-tier appliances including dual ovens, a high-end induction cooktop, oversized island, walk-in pantry, and sunny breakfast nook-opens seamlessly to the family room, where walls of windows, a propane fireplace, and warm finishes create an inviting everyday space. A main-level office provides the perfect work-from-home setup or quiet retreat. Step outside and the lifestyle only gets better-an expansive deck overlooks a private backyard transformed into a true resort setting, featuring a beautifully refinished heated pool with new plaster, glass tile, coping, and updated systems including a high-efficiency variable-speed pump and brand-new heater, along with a fire pit and a dedicated party pagoda-creating an outdoor experience designed for entertaining, relaxing, and making memories all season long. Upstairs, four spacious bedrooms include an extraordinary primary suite with tray ceilings, its own fireplace, a full sitting room, spa-style bath with soaking tub and walk-in shower, and dual walk-in closets that truly deliver. Bedrooms two and three are generously sized and connected by a Jack and Jill bath, while bedroom four enjoys its own private en suite bath. The fully finished lower level offers exceptional versatility with a complete second kitchen, large recreation space, bedroom, full bath, half bath, and private entrance-perfect for an in-law suite, au pair quarters, or independent living opportunity, supported by County R1 zoning. What truly sets this home apart is the level of investment and infrastructure rarely seen-anchored by a state-of-the-art geothermal system that does far more than just heat and cool the home. This advanced system efficiently provides heating, air conditioning, and domestic hot water, supported by multiple deep wells and whole-home zoning that allows individual temperature control in nearly every room. It's a powerful, energy-efficient solution designed to dramatically reduce utility costs while delivering consistent, customized comfort year-round. Paired with a fully owned solar panel system-meaning no lease to assume-the result is a home built for long-term efficiency and sustainability without compromise. Additional major upgrades include enhanced water treatment and filtration, constant pressure well system, upgraded electrical service, irrigation, central vacuum, smart wiring, and a comprehensive alarm system-delivering a home that is not only beautiful, but intelligently built for performance and peace of mind. This is a home that adapts to your life-whether you're hosting, working, growing, or simply enjoying the peace and privacy of an incredible setting-all within a community known for its charm, space, and top-tier schools.
