About this home

Set behind the gates of Spanish Oaks overlooking the 7th hole, The Monolith is a rare architectural statement where bold design, extraordinary craftsmanship, and effortless livability converge. Situated on 0.87 acres, the estate offers approximately 9,883 square feet of living space, plus a detached 1,420 square foot casita and separate flex space, creating a true private resort experience.

Striking architecture, soaring 28 foot ceilings, expansive LuxView glass systems, and disappearing walls of glass blur the line between indoors and out. At the heart of the home is the first fully custom Lamborghini kitchen installed in North America, featuring bespoke walnut cabinetry, sculptural stone surfaces, integrated luxury appliances, and exceptional craftsmanship. A fully equipped chef’s kitchen is discreetly tucked behind, offering professional grade functionality for effortless entertaining.

The private primary suite includes a dedicated office, fitness room, spa inspired bath with heated floors, imported Italian soaking tub, outdoor shower, custom Italian dressing rooms, and integrated laundry. Additional living spaces include a secondary main level suite, media room, built in office areas, four air conditioned garage bays, and a detached guest house ideal for extended stays.

Designed for year round entertaining, the outdoor living spaces feature retractable shades, a gourmet outdoor kitchen, oversized gathering areas, fireplace, and a dramatic two level pool with a true lap pool overlooking the golf course.

Modern conveniences including Savant home automation, integrated audio, built in shades, and thoughtfully concealed technology complement the home’s clean architectural aesthetic.

The Monolith is more than a luxury residence. It is a true one of one.
