About This Home
European-Inspired Estate with ICF Construction on 2.75 acres in the Texas Hill Country. Inspired by the countryside villas of Tuscany and Provence, this Hill Country estate blends modern construction with old-world European architecture. Built with Insulated Concrete Form (ICF), the residence offers exceptional strength, security, energy efficiency, and quiet comfort. The limestone compound features a courtyard layout with guest quarters surrounded by private grounds. The limestone masonry frames steel-and-glass entry doors and black casement windows, while quality materials and craftsmanship define every detail. The residence opens to a grand foyer where a dramatic custom staircase, soaring ceilings, large-format porcelain tile, large chandeliers, and two marble fireplaces create an immediate wow moment. The kitchen features Thermador appliances, an Italian ILVE 48" dual-fuel range, two dishwashers, oversized island, butler’s pantry, soapstone countertops, brass fixtures, and marble backsplash. A screened porch, kennel area, outdoor shower, and full bath are on the main level. Take the elevator up to two guest bedrooms, bath, laundry, and an owner’s suite with marble finishes, claw-foot soaking tub, walk-in shower, coffee bar, and dual closets. The carriage-house apartment offers vaulted ceilings, reclaimed historic wood flooring, full Thermador kitchen, bedroom, marble bath, and two walk-in closets. Air-conditioned garage with three bays. Located in Marble Falls near Horseshoe Bay and Lake LBJ.
At $746 per square foot, 3401 Mormon Mill Rd delivers 4,017 square feet of insulated concrete form construction on 2.75 acres in Marble Falls, a private stretch of Marble Falls, TX 78654 in Burnet County. This is a 2019 residential single family residence priced at $3.00M, and the setting stands out for both scale and build quality.
The layout reads like a true estate instead of a standard Hill Country house. You have 4 bedrooms, 4 baths, a 3-car garage, 2 fireplaces, and a courtyard-style compound that creates separation between the main residence and guest space. The use of ICF construction matters here. It points to better energy performance, stronger storm resistance, and quieter interiors than many custom homes in this part of the market. Inside, the finish level is consistent with the price point. Steel-and-glass entry doors, black casement windows, large-format porcelain tile, marble fireplace surrounds, and a dramatic staircase give the home structure and presence without relying on excess.
The kitchen is built for real daily use and large-scale hosting. Thermador appliances, an ILVE 48-inch dual-fuel range, two dishwashers, a large island, butler’s pantry, soapstone counters, brass fixtures, and a marble backsplash put it firmly in the luxury category. The main level also adds practical features that buyers in this segment notice, including a screened porch, kennel area, outdoor shower, and full bath. Upstairs, the elevator changes how the home lives over time. The owner’s suite adds marble finishes, a claw-foot soaking tub, walk-in shower, coffee bar, and dual closets, while the carriage-house apartment gives guests or extended family a fully independent setup with its own kitchen and bath.
For location, Marble Falls gives you a Marble Falls address with straightforward access along Mormon Mill Road, while Lake LBJ and Horseshoe Bay remain close enough to shape the lifestyle. That matters for buyers who want acreage and privacy without disconnecting from the water, golf, and club amenities that define this part of the Hill Country. From a school standpoint, the home is served by Marble Falls ISD, with Marble Falls Elementary, Marble Falls Middle, and Marble Falls High School. After 34 days on market, the property presents a clear value case for buyers who want modern construction, land, and a long-term hold in one of the strongest lifestyle corridors west of Austin.
