FOX DEN is a rare opportunity to own a work of legacy modernism in the mountains. One of Jim Fox's most celebrated designs, it has been meticulously re-envisioned through a $1.5M+ renovation. This is a sculptural residence perched at 4,100 feet on Satulah Mountain, inside the town limits of Highlands. Fox's dramatic structural concept of four intersecting planes creates a dynamic interplay of geometry, light, and shadow. Walls of glass capture long range vistas of Whiteside, Chimneytop, and Terrapin Mountains, transforming the home into a living observatory of the Blue Ridge landscape. Every system, surface, and finish has been renewed with reverence for the original architecture and an eye toward elevated mountain luxury. The main level is a flowing modernist plan uniting the living, dining, kitchen, and terrace. It includes an organic stacked stone fireplace; custom kitchen with Bosch and Fisher & Paykel paneled appliances; Caesarstone surfaces & Rohl fixtures and sleek cabinetry illuminated by skylights. This level embodies the essence of modern design: sculptural lines, natural materials, and an effortless connection to the outdoors. The upper level is a private retreat framed by triangular windows overlooking the forest canopy. In addition to the bedroom there is a dedicated office/studio space, walk-in closet, loft area and heated marble floors in the bath. It's a serene, architectural escape designed for reflection, creativity, and quiet luxury. The lower-level centers around a lounge anchored by a mid century Brutalist fireplace and dry bar. Three generous guest suites each offer newly renovated en suite baths and private decks with forest and mountain views. The expansive lower deck reveals the home's cantilevered diamond form structure, a breathtaking example of Fox's engineering artistry. It serves as a dramatic outdoor venue for cooking, dining, and fireside evenings. FOX DEN has been featured in multiple books and Fine Homebuilding Magazine, recognized for its bold geometry and modernist innovation. Highlands, NC was named America's Best Small Mountain Town by Travel & Leisure (2023) providing an exceptional setting for a home of this caliber. This is more than a residence. It is a collectable architectural treasure, a luxury mountain retreat with pedigree, provenance, and soul-ready for its next steward.
