Texas character meets refined modern design on 1.16 acres in sought-after Rayner Ranch community of Spring Branch. This thoughtfully designed single-story custom home offers 4 bedrooms, 3.5 baths + private home office with upscale finishes throughout. Built with accessibility and long-term comfort in mind, the home features 42 wide hallways, ADA-compliant doors, and dual primary suites with recessed roll-in showers, grab bars, and abundant storage. The open-concept kitchen is a chef's dream with quartz counters, an oversized island with seating and built-in outlets, Rev-A-Shelf organizers, undercabinet lighting, custom cabinetry, and motion-sensor lighting in the pantry and back hall. A French-door study, formal dining with butler's pantry and dry bar, and cathedral-ceiling living room with wood beams and fireplace complete the heart of the home. Outside, a covered patio with wood ceiling overlooks a fenced yard shaded by 36 mature oak trees and accented by a greenhouse, fig trees, and solar-lit fencing. The property is casita-ready with water, sewer, and electric hookups already in place, offering room for future guest quarters, pool, or workshop. Additional highlights include 4-side masonry construction with gutters, a 500-gallon propane tank, Ring security system, water softener, RO system, tankless water heater, and an oversized side-entry garage with attic storage and insulation. Conveniently located near Canyon Lake, Guadalupe River, Bulverde, and New Braunfels, this home provides a rare opportunity to enjoy privacy, functionality, and refined Hill Country living in a gated community with Serenity Oaks amenities.
