Tucked in one of the most discreet pockets of Preston Hollow, this residence is an architectural tour de force of monumental scale, volume, and craftsmanship. Conceived through the exclusive collaboration of builder Mark L. Rose, Curtis Burlbaw of Blue C Designs, and Richard Drummond Davis Architects, 1 Dorset stands as a one-of-one custom build. Spanning 18,614 SF in total, including a 15,749 SF main residence and a 2,865 SF private quarters, the fully gated estate is anchored by a dramatic three-sided negative edge pool and intentional serenity. The Lueders limestone exterior and Ludowici roof are a testament to the home's museum-quality materials. A Level 5 wall finish, soundproof walls, and concrete crawl space speak to the engineering integrity rarely seen in residential construction. The interiors are quietly opulent, defined by soaring volumes and exacting detail: Farrow & Ball paint, Ann Sacks tile, floating staircases with solid brass accents, and slab marble sourced and installed by Il Granito. Steel doors by Metro, curated lighting by Lutron, and home automation via Savant complete a flawless technological backbone. The home includes appliance packages by Miele, Wolf, and Sub-Zero--not just in the main kitchen, but replicated in the catering kitchen, bar, gym, game room, media suite, and guest house. Outside, the estate is equally fortified for entertaining with an expansive outdoor kitchen and covered living spaces seamlessly blending inside and out. This is a statement property--unapologetically grand, impossibly private, and beyond comparison in Dallas' luxury landscape.
