About this home
Welcome to 605 Casasanta, an exceptional custom residence in the highly coveted, gated waterfront community of The Peninsula at Rough Hollow. This newly completed home showcases amazing craftsmanship and thoughtful design, with every detail executed to the highest standard. From premium finishes to cutting-edge building specifications (see documents), no expense has been spared in creating a residence that exemplifies refined luxury and timeless sophistication. Builder Perks: extensive blind package, 1-year landscaping maintenance, 1 year pool maintenance, plus nearly 30 hours of moving/organizing/setup for new owners. This sprawling 5,216 sq. ft. single-story residence is gracefully positioned on a premier corner lot, complete with a circular drive and backing to lush green space. Designed with both luxury and function in mind, the home features four spacious bedrooms with en suite baths, half bath, a private study, media room and a unique four-car garage. 4th car garage perfect for home gym. The seamless indoor-outdoor experience is highlighted by a resort-style pool, outdoor kitchen, and curated landscaping. Inside, soaring ceilings set a dramatic tone, including 20’ ceilings in the study and 15’ ceilings in the dining room, family room, and game room. The gourmet kitchen is outfitted with professional-grade appliances, including a 60” built-in Sub-Zero refrigerator/freezer, a 48” Wolf range, and dual Cove dishwashers. A fully appointed Butler’s Pantry complements the space with a Wolf oven and speed oven, Scotsman ice machine, and an additional 36” refrigerator. Modern sophistication is showcased throughout with sleek LuxView exterior doors and windows, linear air conditioning vents, and trim less 2” square recessed lighting.
