A 1924 Spanish Revival Estate in Historic Old Pasadena. Beyond the 19th Century wrought-iron gates of one of St. Petersburg’s most coveted historic neighborhoods lies Casa Ronda—a rare and enchanting estate inspired by the Spanish and Moorish timeless architecture of the town of Ronda, Spain. Set among brick streets and mature landscaping, this remarkable residence evokes old-world elegance, architectural artistry, and a sense of calm that feels worlds away from the everyday. Built in 1924 for William G. Marvin, a prominent and internationally recognized New York City attorney, Casa Ronda was designed to his exacting specifications during the early development of Pasadena Estates. The home has since been meticulously maintained and thoughtfully updated, preserving its historic soul while accommodating modern living. Occupying a coveted corner double lot, the property is enveloped by ivy-covered walls, majestic trees, and gated privacy. Alley access leads to a detached two-car garage, complemented by a side gate providing additional parking—an exceptional feature in this historic setting. Inside the main residence, 9’ ceilings, original wood floors, arched doorways and hand-painted murals immediately set the tone. An arched front entry opens to a gracious coat room and step-up foyer, flanked by wood-spindled doors leading to a series of elegant living spaces. The living room is anchored by a distinctive sloped mantel fireplace, while the dining room is bathed in natural light from expansive windows. From the diniing room and through the butler’s doorway, you’ll find that the updated kitchen is both refined and functional, offering modern conveniences such as a gas stove, stainless steel appliances, farm sink, wine coolers, and a drawer microwave, while remaining true to the home’s character. While the charming parlor situated in the center of the home with outdoor views is a cozy space to watch TV, the dramatic curved staircase crowned by a glass oculus complete this architectural masterpiece. The garden room beyond the living room, provides a versatile living space with seamless access to outdoor dining and seating beneath an arched rear porch. Here, a drop-down screen transforms the space into an open-air cinema for unforgettable evenings. Upstairs accommodations include two guest bedrooms connected by a Jack-and-Jill bathroom, a private balcony accessed by the east guest bedroom, as well as a serene primary suite featuring a private balcony, walk-in closet, and an updated en-suite bathroom with marble finishes, ample built-in storage and a separate water closet. The detached charming casita, “Casita Rondita”, is ideal for guests, extended family, or as a private retreat, features one bedroom, a bathroom with shower, cozy seating area, and kitchenette. Outdoor living is elevated with a heated salt water pool, outdoor shower, tranquil fountains found throughout the grounds, and an enclosed circular gazebo offering flexible use for relaxation, or creative pursuits. A generator provides power to the casita and select essential appliances in the main house. Not situated on flood zone and yet, with close proximity to Gulf beaches, downtown Gulfport, and downtown St. Petersburg, Casa Ronda offers an extraordinary blend of historic elegance, privacy, and vibrant coastal living. This is not merely a home—it is a legacy property, rich in story, beauty, and timeless appeal.
