Located at 730 N Mashta Drive, the recently listed home was sold in just 4 months by agent Joan Bruggink with ONE Sotheby’s International Realty in as a result of a connection made on Instagram. Her innovative marketing strategies, strong work ethic, and extensive international network acquired through extensive travel played a pivotal role in the rapid and successful closing of the sale.

Grand living is enhanced by telescopic sliding doors, creating a seamless flow with the outdoor area. A formal dining room is separated by a 288-bottle glass wine vault. Gourmet kitchen with gas stove, Miele and Bosch appliances, wine cellar, porcelain and quartz countertops, and kitchen bar. The home also features additional office, laundry room, storage and a 2-car carport garage. Outdoors, the residence features breathtaking sunsets from the rare 3rd floor rooftop terrace. The backyard features a lush garden, with heated pool, jacuzzi, and a charming BBQ gazebo.

Joan Bruggink of ONE Sotheby’s International Realty has her finger on the pulse of the South Florida real estate market from Key Biscayne to Southwest Ranches. A native of the Netherlands, where she first began her real estate career, Joan split her time working for a Dutch developer in South America and her home country. Eventually, she moved to Miami in 2012 to elevate her career and fully immersed in the dynamic South Florida luxury real estate market, focusing on a diverse range of properties, including off-market listings, new construction projects, investment condos, and single-family homes. Joan has already closed over $10 million in sales this year and is determined to make this her best year yet! In addition to being an agent, she provides full white glove service to her clients and is an advocate for sustainable luxury home and living.
