for $1,150,000 with 5 bedrooms and 3 full baths, 1 half bath. This 3,526 square foot home was built in 2021 on a lot size of 3.09.
Welcome to 144 Lilly Lane, a masterfully executed custom estate in the exclusive gated community of Trinity Oaks Preserve. Completed in 2021, this residence embodies Hill Country elegance on over three private acres, secured by a 70-foot deed-protected greenbelt. The 3,526 sq ft single-story floor plan was brilliantly designed for modern living, featuring dual primary suites on opposite wings for ultimate privacy, five total bedrooms, a dedicated office with a fireplace, three full baths, and a convenient pool half-bath. Upon entry, the open-concept living area makes a grand statement with soaring vaulted ceilings, a dramatic floor-to-ceiling stone fireplace, and a wall of Pella Low-E windows that dissolve the boundary between indoors and the serene oak-studded landscape. The heart of this home is the chef's kitchen, a showcase of function and style. It features a magnificent ten-foot marble island, a premium induction dowdraft cooktop, and custom cabinetry locally milled to perfection. Behind this polished facade lies the home's secret weapon for entertaining: a truly hidden butler's pantry. This incredible space houses a wet bar, wine fridge, beverage cooler, deep freeze, and a stand-alone ice maker, allowing for effortless hosting while maintaining pristine main kitchen aesthetics. Additional custom details like a concealed coffee bar and a baker's hutch elevate the experience. The main primary suite forms a secluded owner's wing, a true sanctuary of restorative luxury. It features a tray ceiling and a programmable electric fireplace, while oversized windows offer tranquil views. Its spa-inspired bath is a work of art, with a freestanding double slipper tub positioned beneath a chandelier and a third fireplace. The oversized, LED-lit walk-in shower, dual vanities with a dedicated makeup station, a heated towel warmer, and two large custom closets complete this opulent retreat. This home is an engineering marvel, **built to uncompromising standards.** The entire structure is encased in a full spray foam envelope (R30+), ensuring remarkable energy savings. Peace of mind is guaranteed by a whole-house generator capable of running the entire property for extended durations. The infrastructure includes dual HVAC units (one with dual zones), two on-demand tankless propane water heaters, and a 30,000-gallon rainwater collection system. A proactive, custom-engineered drainage system with French drains and sump pumps ensures the grounds remain impeccable. The outdoor spaces are a private resort curated for an idyllic Hill Country lifestyle. A majestic oak tree forms a natural, welcoming archway on the path to the stunning custom in-ground pool, which features a vanishing infinity edge and a heated spa. Entertain on a grand scale across multiple covered patios, including a nearly 50-foot rear patio with a wood-burning stove and a 20x20 pool pavilion with a full outdoor kitchen. The property is secured by high-end, welded drill stem pipe ranch fencing, offering open views for **spectacular sunsets and brilliant, star-filled night skies.** Enjoy serene country living just minutes from Baylor Scott & White hospital, the future Flat Rock Creek retail center, Marble Falls, and Lake LBJ. With Austin's Bee Cave Galleria only 35 minutes away, **this property is not just a home, but a legacy Hill Country retreat.** With too many features to list, ask your Realtor for our property inclusions addendum.
