Along a quietly prestigious stretch of sand between Bal Harbour and Miami Beach, Surfside has emerged as one of South Florida’s most tightly held oceanfront enclaves. Defined by architectural restraint, privacy, and an increasingly rare sense of scale, the town’s evolution is perhaps best embodied by the newly unveiled $70 million penthouse at Ocean House, a boutique, 25-residence development rising at 9317 Collins Avenue.

Positioned atop the building as a two-level, full-floor residence with a private rooftop, the penthouse represents a category of coastal living that has become nearly impossible to replicate. With approximately 9,476 square feet of interior living space and 5,051 square feet of outdoor terraces, the residence spans roughly 14,527 square feet in total, offering uninterrupted views of the Atlantic Ocean, the Miami skyline, and the surrounding coastline.

Developed by Multiplan Real Estate Asset Management, Ocean House is intentionally intimate in scale, a defining characteristic in a market increasingly dominated by high-density towers. Here, the emphasis is on discretion and livability rather than spectacle. According to Managing Partner Marcelo Kingston, the penthouse reflects a broader shift at the top of the market toward homes that feel serene and deeply connected to the water, while maintaining a sense of quiet elevation above it all.

Architecturally, the residence is framed by a transparent façade and wraparound floating balconies that dissolve the boundary between indoors and out. Interiors by Carla Guilhem Design lean into restraint and naturalism, favoring flowing lines, tactile materials, and a palette that allows light and horizon to take center stage throughout the day. The result is a home that feels less like a showpiece and more like a private retreat shaped by its coastal setting.

The kitchen is designed as both a functional and social anchor, featuring sculptural cabinetry, waterfall gourmet islands, and Gaggenau appliances. Throughout the private living quarters, spa-like bathrooms with natural-stone soaking tubs and elevated finishes reinforce a sense of ritual and calm, transforming everyday routines into moments of restoration.

Beyond the main living spaces, the penthouse offers a suite of dedicated amenities typically reserved for private estates. These include an intimate cinema, a spa, a state-of-the-art fitness area with a private training room, and a game room complete with billiards and a bar. Above it all, the private oceanfront rooftop is conceived as a destination in its own right, with a pool, spa, expansive lounge areas, and a summer kitchen designed for dining and entertaining high above the shoreline.

Within the broader context of Surfside, opportunities of this scale are exceedingly rare. Ocean House’s limited collection of residences, combined with a full-floor penthouse and private rooftop, places the offering firmly in trophy territory for buyers seeking privacy, architectural pedigree, and direct oceanfront access in a boutique setting.

Sales and marketing for Ocean House are led by Gutman Development Marketing. The project is currently under construction by Moss Construction and is slated for completion in 2027. For more information, visit oceanhouseresidences.com.
