About this home

Welcome to “The Ponderolo,” a one-of-a-kind architectural treasure located just minutes from Old Town Monrovia, nestled within the city’s beloved historic residential corridor. A true head-turner, this iconic residence has been cultivated over many years, resulting in a home rich in character, craftsmanship, and global inspiration. This distinctive property features 3 well-appointed bedrooms and 2 bathrooms, with the original 4th bedroom thoughtfully converted into a game room ideal for entertainment. The home sits behind a circular driveway framed by solid metal electric gates that provide both privacy and presence. The exterior is artfully curated with stone accents and sculptural cacti, setting the tone for the unique experience inside. Step through the front door into a living room anchored by a striking stone fireplace, where a custom ceiling—expertly designed with copper and rope detailing—creates a warm, inviting ambience. Just off the living room, an expansive entertainment lounge offers an ideal setting for gatherings, complete with a built-in bar and guest bath. The kitchen blends charm and functionality with newer appliances, a central island, and a dedicated wash sink. Adjacent to the dining area, an extended flex space with its own fireplace provides additional room for relaxation, creativity, or hosting. The home’s three bedrooms are thoughtfully positioned, with the primary suite offering its own fireplace and sliding doors that open directly to an outdoor patio—an ideal retreat for morning coffee or evening unwinding. Outdoors, the property transforms into an entertainer’s paradise with three beautifully positioned patios, each offering its own unique setting for gatherings, dining, or quiet reflection. The impressive 4-car garage is a standout feature—equipped with a built-in sound system, temperature control, and ample space for motorcycles, collectibles, or a personal workshop. No expense was spared in creating this exceptional space. Additional upgrades include a solar system, EV charger, and RV washout. The generous lot also provides an excellent opportunity to add an ADU and/or a pool, offering even more potential for customization. The owner’s world travels are reflected throughout the home, where curated pieces are displayed with museum-like intention. Every corner tells a story, and the experience feels like stepping into a private gallery of craftsmanship and culture. The Ponderolo welcomes you home!
