Multiplan REAM Reveals $70 Million Penthouse at Ocean House in Surfside Designed by Carla Guilhem Design

Multiplan Real Estate Asset Management has revealed the $70 million Penthouse at Ocean House, a rare two-level, full-floor offering atop the 25-residence boutique oceanfront development under construction at 9317 Collins Avenue in Surfside.

Set between Bal Harbour and Miami Beach, Surfside has quietly ascended as one of South Florida’s most exclusive oceanfront enclaves, defined by architectural pedigree, timeless luxury, and a limited collection of world-class residences. Within this prestigious stretch of coastline, Ocean House stands as the crown jewel, offering a rarity of scale and design seldom found in the area.

“At the top of the market, buyers are gravitating toward homes that feel intimate and serene, with the ocean always present,” said Marcelo Kingston, Managing Partner at Multiplan REAM. “This penthouse is a statement of how people want to live now, quietly elevated, deeply private and anchored near the water.”

Spanning the building’s whole top floor plus a private oceanfront rooftop, the duplex penthouse is positioned for uninterrupted views of the sea, sky, and city. Across both levels, the total is approximately 9,476 square feet of interior living space and 5,051 square feet of outdoor terraces, for a combined total of roughly 14,527 square feet.

Ocean House captures the refined intimacy that has made Surfside a magnet for discerning buyers seeking privacy, proximity, and prestige. “This residence is a true coastal sanctuary, designed to feel like a retreat,” commented Kingston. “It’s refined coastal living at its most livable, with spaces that bring a sense of ease and balance you can feel the moment you arrive.”

Framed by a transparent façade and wraparound floating balconies, the residence is designed to create seamless harmony between design and nature, with interiors shaped by flowing lines, natural textures, and an effortless connection to the outdoors curated by Carla Guilhem Design.

“In a home like this, the most important gesture is restraint,” said Carla Guilhem, lead interior designer of Carla Guilhem Design. “The spaces are meant to feel intuitive and serene, so the horizon and the changing light become part of the experience from sunrise to sunset.”

The penthouse kitchen features waterfall gourmet islands, sculpted cabinetry and Gaggenau appliances. Private areas are envisioned as retreats, with spa-like bathrooms featuring natural-stone soaking tubs and elevated finishes that bring a sense of calm and ritual to everyday moments.

Dedicated entertaining and wellness spaces include an exquisite game room with billiards and a bar, an exclusive cinema, a spa, and a state-of-the-art fitness area with a private training room. The private rooftop is designed as a destination in itself, with an expansive terrace lounge, pool, spa, and a summer kitchen for dining and hosting above the ocean.

“Surfside remains one of South Florida’s most coveted enclaves, and opportunities at this scale are exceptionally rare,” said Kingston​​. “This penthouse delivers the rarity buyers are seeking right now, with a full-floor residence and private rooftop in a boutique oceanfront building defined by design and discretion, a true gem within the area’s most distinguished stretch of sand.”

Sales and marketing are led by Gutman Development Marketing. Ocean House is currently under construction by Moss Construction and is slated for completion in 2027.

Multiplan REAM Reveals Oceanfront Ultra-Luxury Boutique Condo 'Ocean House' in Surfside

Multiplan Real Estate Asset Management (REAM), the developer behind the luxurious 57 Ocean, has officially launched sales for Ocean House, an exclusive collection of 25 ultra-luxurious residences in the coveted Surfside enclave. The boutique development combines the best of both worlds, the seclusion and grandeur of a private high-end residence with the ease and convenience of modern condominium living. Residents will enjoy an exceptional oceanfront lifestyle in a truly exclusive setting. Multiplan REAM will conduct sales in-house by appointment only with prices starting at $5 million.

“Surfside’s unparalleled location and serene ambiance have solidified its status as the premier destination for discerning buyers in Miami’s ultra-high-end waterfront market,” said José Isaac Peres, Founding Partner of Multiplan REAM. “We are thrilled to introduce Ocean House, a project we believe will redefine luxury living in the city. We are confident this extraordinary project will thrive within this prosperous community.”

Located at 9317 Collins Avenue, the boutique condominium offers two- to five-bedroom designed to epitomize the Surfside lifestyle. Renowned architecture firm Arquitectonica and its faction ArquitectonicaGEO is spearheading Ocean House's architectural and landscape design. Their vision offers unsurpassed architecture, with Bernardo Fort-Brescia conducting it, and featuring expansive east, south, and west views. Designer Carla Guilhem, with her practice focusing on yachts and homes, cleverly cross-pollinates ideas between the two, bringing her signature style to the interiors of the residences, creating sophisticated spaces that complement the oceanfront setting.

Ocean House stands out with its distinctive emphasis on privacy and tranquility, offering a full suite of wellness-focused amenities spread across three meticulously designed floors. Each space is beautifully infused with beach-inspired hues, wooden accents, and natural stone flooring. From the rejuvenating spa with treatment room, salon, steam room, and expansive rooftop pool deck to a vitality pool and a state-of-the-art fitness center, every detail has been thoughtfully curated to enhance well-being. Additional components are integrated into the lush tropical landscape, reflecting ponds, floating cabanas, and intimate lounges.

"Unlike the impersonal high-rise developments prevalent in South Florida, Ocean House offers an intimate, exclusive experience” said Marcelo Kingston, Managing Partner at Multiplan REAM. “It is a harmonious blend of privacy, architectural brilliance, and unparalleled amenities, designed with the sophisticated buyer in mind. With breathtaking waterfront views, lavish interiors, and a limited collection of residences, Ocean House is a truly exceptional offering within Surfside's coveted coastline and Miami’s burgeoning luxury real estate market.”

Ranging in size from 2,093 SF to 6,279 SF, each residence will feature expansive floor-to-ceiling windows, a grand living room with natural stone flooring, and an open-concept kitchen that centerpieces a custom-designed Silestone island with a waterfall edge and private terraces offering breathtaking views of the Atlantic Ocean. Elegant finishes and fixtures include custom European cabinetry, Gaggenau kitchen appliances, and bathrooms with spa-like touches – a vanity with double sinks, a glass-enclosed rainfall shower, and a freestanding tub that evokes serenity.

"Surfside has become the most sought-after market to live in South Florida, the scarcity of either available land or new projects in this area makes Ocean House a true gem in the strong Miami condo luxury market. Our project stands out in this community as a true luxury, boutique development offering buyers a once-in-a-lifetime opportunity to own a villa in the sky on the ocean," said Phil Gutman.

Multiplan REAM has commenced the demolition of the two-story structure of the old Regent Palace Condominium to clear the site in anticipation of the groundbreaking, slated for the first quarter of 2025, and Ocean House is anticipated to be delivered in 2027.

"Our go-to-market strategy will be highly selective and focused. By self-financing projects, Multiplan gains the flexibility to initiate construction immediately while patiently pursuing high-caliber buyers who share our vision for Ocean House as Miami's most exclusive beachfront condo community," concluded Kingston.
