BRAn Exceptional Country Estate in the Heart of the City!!! Rarely does a property of this caliber present itself at a valuation so compelling — a newly completed 1.5-story residence set upon 1.25 pristine acres, offered meaningfully below its independently appraised value. This is not simply a home; it is a considered way of life, where the serenity of estate living meets the convenience of one of the region’s most coveted addresses. Behind a quiet, HOA-free setting lies a residence of remarkable intention. Five generously proportioned bedrooms, five designer bathrooms, a dedicated home office, and a private media room speak to both the scale and the thoughtfulness of the floor plan. The chef’s kitchen — open, luminous, and artfully appointed — flows naturally into the living spaces, inviting both intimate evenings and effortless entertaining. The primary suite transcends expectation, offering a spa-inspired retreat of genuine repose. Beyond the residence itself, the 1.25-acre grounds afford a canvas of extraordinary potential: room for a resort-style pool, guest quarters, lush gardens, or simply the rare luxury of unencumbered space within city limits. Positioned with exceptional access to Highway 75 and the George Bush Turnpike, the estate places Plano within a fifteen-minute reach and downtown Dallas, DFW International Airport, and Love Field within thirty — while top-tier dining, retail, and the shimmering shores of Lake Ray Hubbard remain mere moments away. For the discerning buyer who has long sought the harmony of acreage, new construction, and metropolitan proximity — without compromise and without an association — this offering represents a singular and time-sensitive opportunity.
