About this home
The Golden Lion Estate is a bold, masterfully reimagined residence in Boca Raton, conceived and executed by the award-winning Errez Design. This ultra-luxury designer home is distinguished by architectural originality and an uncompromising commitment to the world's finest materials and craftsmanship. The interiors reveal a sophisticated fusion of contemporary refinement and Asian-inspired artistry, thoughtfully curated to reflect visual harmony. Rich textures, layered materials, and disciplined yet expressive color compositions create a gallery-level environment; an offering rarely encountered in Boca Raton. Overlooking the rolling fairways of The Boca Raton golf course, The Golden Lion Estate occupies a coveted corner lot and offers privacy, security, and refined living. Set within the prestigious, double-gated enclave of Addison Estates, the residence stands as the community's crown jewel. Layers of controlled access, a generous side yard, lush landscaping, and a resort-style pool establish a private sanctuary within one of Boca Raton's most exclusive addresses. Spanning a total of 6,516 SF, the home delivers architectural presence, sophistication, and tranquility throughout. The residence offers five bedrooms, six full baths, and a powder room, anchored by a grand first-floor primary suite designed as a private, serene retreat. Every element of the home has been comprehensively reimagined, including the installation of all new doors and windows in 2025. At the heart of the home, the reimagined kitchen and lounge function as an elegant living environment rather than a traditional culinary space. Modern cabinetry, an antique mirror backsplash above the range, a concealed pantry, and a custom bar integrated into the dining area allow for seamless entertaining while maintaining visual serenity. The space flows effortlessly into a connected den, ideal for intimate gatherings or refined hosting. The dining room reveals a true artistic centerpiece, a bespoke hand painted gold leaf mirror mural by renowned English muralist Grahame Ménage. First unveiled at a Palm Beach show, this Asian inspired installation transforms the room into a museum quality experience where fine art and architecture converge. The second floor is designed as an elevated private retreat, anchored by a spacious living lounge with custom millwork built ins, ideal for media, gaming, or relaxed family living. In addition to the dramatic oversized guest suite featuring custom bunk beds and two separate, beautifully appointed bathrooms, the second level offers three additional private bedroom suites. Each is thoughtfully designed to provide comfort, privacy, and refined accommodations for family and guests. Throughout the home, refined flooring selections create a layered visual narrative, including travertine on the main level, Casa Venetia European oak on both floors, elegant parquet detailing, and a dramatic herringbone pattern in the primary suite. The primary bath rivals a luxury spa, showcasing luminous onyx behind the soaking tub and Bianco Montcarte marble throughout the floors and shower walls. Outdoors, sweeping golf course vistas frame the resort style pool and tranquil entertaining areas, reinforcing the estate's sense of privacy and seamless indoor outdoor living. The property also includes a laundry room and a two car garage. Opportunities of this caliber - where architecture, art, security, and lifestyle converge - are exceedingly rare in South Florida. The Golden Lion Estate is not merely a residence; it is a definitive expression of refined living at the highest level.
