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. Energy-efficient design features include foam insulation in roof and walls, two tankless water heaters, three high-performance HVAC units, a dehumidifier, and a Level 2 EV charging station in the garage.

The circular drive at 605 Casasanta Trail announces arrival the moment you enter the gated waterfront community of The Peninsula at Rough Hollow in West Lake Hills, where this newly completed 5,216 square foot residence commands a corner lot backing to protected greenbelt. The single-story home rises to meet dramatic architectural ambition with 20-foot vaulted ceilings in the study, 15-foot heights across the dining room and family room, and sightlines that stretch unbroken through an open floor plan anchored by a gourmet kitchen built for serious cooking.

The kitchen alone justifies the $4.25 million price. A 60-inch Sub-Zero refrigerator-freezer anchors the primary workspace. A 48-inch Wolf range with dual ovens and speed oven, flanked by Cove dishwashers and warming drawers, positions this kitchen as the genuine centerpiece of the home. The butler's pantry extends the functionality with a Scotsman ice machine, third refrigerator, and additional Wolf oven. This is construction that reflects genuine specification standards, not marketing language.

Four en suite bedrooms provide privacy within the layout, with the primary suite occupying the main level. Two primary closets offer storage architecture that anticipates actual living. The home includes a media room, private study, and dedicated game room, each with the ceiling heights and lighting design that define the property's overall impact. Smart home systems integrate thermostats, lighting, and security throughout. A four-car garage accommodates vehicles and lifestyles, with the fourth bay capable of conversion to home gym space.

The resort-style pool and outdoor kitchen extend the living space beyond walls. An automated sprinkler system waters the xeriscape and established trees on the 0.9658-acre lot. A Level 2 EV charging station sits ready in the garage. The building envelope itself performs at high specification: spray foam insulation, two tankless water heaters, three high-performance HVAC units, and a dehumidifier manage both comfort and efficiency.

The Peninsula at Rough Hollow feeds into Lake Travis ISD, with Rough Hollow Elementary serving younger residents and Lake Travis Middle and High Schools anchoring secondary education. The location positions daily commutes toward tech corridors and downtown Austin without the density that defines central neighborhoods.

This property delivers the thing that matters most in luxury real estate: nothing left undone and nothing left to imagine.
