Surfside’s luxury real estate market just gained its most significant offering. Ocean House introduces a $70 million penthouse that occupies the building’s entire top floor plus a private rooftop sanctuary above the Atlantic.
Multiplan Real Estate Asset Management developed this boutique 25-residence oceanfront property at 9317 Collins Avenue. The timing follows Surfside’s record-breaking $86 million condominium sale in November 2025, which established a new Miami-Dade benchmark and confirmed the area’s status among the world’s most exclusive residential addresses.
Between Miami Beach and Bal Harbour
The location works. Surfside sits between Miami Beach’s energy and Bal Harbour’s refined calm. Ocean House captures this balance through intimate scale and oceanfront positioning. The penthouse spans the building’s entire top floor while commanding a private rooftop, creating a vertical estate above the water.
“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.”
The numbers tell part of the story. Approximately 9,476 square feet of interior living space. Another 5,051 square feet of private outdoor terraces. Total living area: roughly 14,527 square feet. But these dimensions matter less than what they contain. This residence captures the serenity that draws the world’s most discerning buyers to Surfside, much like other exceptional penthouses around the world.
Arquitectonica’s Transparent Vision
The penthouse design centers on harmony between interior space and natural environment. Arquitectonica conceived a transparent façade punctuated by wraparound floating balconies that hover above the Atlantic’s endless expanse.
“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.”
The architectural approach embraces transparency and flow. The horizon becomes an integral element of interior design. Every room benefits from unobstructed ocean views. Natural light and shadow create an ever-changing canvas throughout the day.
Carla Guilhem’s Interior Philosophy
The interior spaces come from internationally acclaimed Carla Guilhem Design. Her inspiration draws from sophisticated yacht living while incorporating natural materiality that speaks to the coastal environment. Guilhem‘s practice spans opulent residences and luxury yachts, bringing cross-pollinated ideas between these two realms of ultra-luxury living.
“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 Brazilian designer, educated in Italy and Spain, infuses the residence with international sophistication while maintaining the relaxed elegance that defines Miami’s luxury lifestyle. Her approach ensures luxury feels deeply personal rather than ostentatious. Spaces enhance rather than compete with surrounding natural beauty.
Culinary Spaces and Entertainment
The penthouse’s culinary spaces reach the pinnacle of contemporary kitchen design. Waterfall gourmet islands crafted from premium natural stone combine sculptural beauty with practical excellence. Sculpted cabinetry provides storage and visual interest. Top-of-the-line Gaggenau appliances ensure every culinary endeavor meets professional standards.
The kitchen’s design extends beyond functionality. Cooking becomes a meditative art form. Ocean views integrate into meal preparation, connecting culinary activities with surrounding natural beauty.
Wellness and Private Retreats
True luxury lies in the quality of private moments. The penthouse dedicates significant space to wellness and retreat. Spa-like bathrooms feature natural-stone soaking tubs that transform daily rituals into moments of restoration. These spaces incorporate elevated finishes that bring calm and ceremony to everyday experiences.
Dedicated wellness areas include a state-of-the-art fitness center with private training room. Residents maintain physical wellbeing without leaving their oceanfront sanctuary. A dedicated spa area provides professional-grade facilities for relaxation and rejuvenation.
Entertainment Excellence
The penthouse’s entertainment spaces reflect sophisticated understanding of how luxury buyers wish to share their homes. An exquisite game room featuring professional billiards equipment and fully equipped bar creates intimate settings for casual entertaining and friendly competition.
The private cinema represents ultimate at-home entertainment luxury. Professional-grade audio-visual equipment sits within a setting designed for comfort and immersion. This space allows residents to enjoy the latest films or sporting events in an environment that rivals the world’s finest private screening rooms.
The Private Rooftop Paradise
The penthouse’s most extraordinary feature: its private rooftop sanctuary. This expansive terrace functions as a private resort suspended above the Atlantic, featuring multiple zones designed for different aspects of leisure and entertainment.
The rooftop pool provides refreshing escape while maintaining panoramic ocean views. The adjacent spa offers warm-water relaxation under South Florida sun. A sophisticated summer kitchen enables al fresco dining and entertaining, complete with professional-grade appliances and elegant outdoor furnishings.
This space hosts intimate gatherings or large celebrations while maintaining privacy and exclusivity. Whether greeting sunrise with morning yoga or hosting sunset cocktails with friends, the rooftop provides an unparalleled setting for life’s memorable moments.
Surfside’s Luxury Renaissance
The penthouse debut reflects Surfside’s broader transformation into one of South Florida’s most prestigious residential addresses. The community’s appeal lies not merely in oceanfront location, but in its commitment to maintaining intimate, village-like atmosphere while providing access to world-class amenities and cultural attractions.
“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.”
Recent sales data supports this assessment. Surfside’s November 2025 record-breaking $86 million transaction demonstrated the market’s appetite for ultra-luxury oceanfront properties. The Ocean House penthouse represents the next evolution in this trend, offering buyers an opportunity to acquire not merely a residence, but a lifestyle defined by exclusivity and sophistication, similar to other luxury real estate markets like Sunny Isles Beach’s high-end developments.
Construction and Timeline
Ocean House benefits from Moss Construction’s expertise, whose reputation for delivering luxury projects to the highest standards ensures every aspect meets the exacting requirements of ultra-high-net-worth buyers. The construction timeline anticipates completion in 2027, allowing sufficient time for meticulous attention to detail.
The development process emphasizes sustainability and environmental responsibility, reflecting Multiplan REAM’s commitment to projects that enhance rather than detract from their natural surroundings. Ocean House contributes positively to Surfside’s long-term environmental health while providing residents with guilt-free luxury.
Market Position
At $70 million, the Ocean House penthouse positions itself within the upper echelons of South Florida’s luxury market, competing with the finest oceanfront properties from Fisher Island to Palm Beach. The pricing reflects the residence’s exceptional amenities and location, plus its rarity within a market where full-floor penthouses with private rooftops remain extraordinarily scarce.
The investment thesis extends beyond immediate luxury to encompass long-term value appreciation driven by Surfside’s limited development opportunities and growing reputation as a luxury destination. With only 25 residences in the entire Ocean House development, the penthouse represents one of the few opportunities for buyers to secure a position within this exclusive community.
Sales and Marketing
Sales and marketing efforts are spearheaded by Gutman Development Marketing, whose expertise in ultra-luxury real estate ensures the penthouse reaches the appropriate global audience of qualified buyers. Their approach emphasizes the residence’s unique qualities while respecting the discretion that defines the luxury market’s upper reaches.
The marketing strategy recognizes that buyers at this level seek more than impressive statistics. They desire properties that enhance their lives while reflecting personal taste and lifestyle preferences. The Ocean House penthouse’s appeal lies in its ability to provide both sanctuary and statement, privacy and prestige, much like the thoughtful curation found in luxury lifestyle offerings.
A New Standard
The Ocean House penthouse represents more than a single exceptional residence. It establishes a new benchmark for what coastal luxury can achieve when architectural excellence meets environmental sensitivity and design sophistication. As Surfside continues its evolution into one of the world’s premier oceanfront destinations, this penthouse stands as evidence of the possibilities that emerge when vision meets execution at the highest level.
For those fortunate enough to call this remarkable residence home, the Ocean House penthouse offers something increasingly rare: the opportunity to live suspended between sea and sky, surrounded by beauty while maintaining the privacy and tranquillity that true luxury provides.
