About 455 Sun Valley
Poised on a coveted 1.07-acre open-water expanse, this newly built transitional lake estate, crafted by premier Dallas builder Jennifer Duncan and Lloyd Lumpkin Architect, redefines waterfront living. Every detail is thoughtfully curated to dissolve the boundaries between indoors and out—sunlight spilling through walls of glass, warm natural wood accents softening the modern lines, and a palette of textures enriched by designer lighting, statement wallpapers, and bespoke cabinetry. The main level is anchored by a tranquil primary suite, a private sanctuary with lake views, while three additional guest suites offer uncompromising comfort. Upstairs, a spacious bunk room welcomes family gatherings, and a game room above the three-car garage seamlessly adapts to work, play, or retreat. Escape, explore, and enjoy a lifetime of memories at the 505 Ranch-all only 45 minutes from Downtown Dallas. Experience luxury lake living with amenities such as: the equestrian center and riding arena, ATV trail, skeet range, clubhouse and pool, guest cottages, fishing, sailing, and much more.
