A truly one-of-a-kind offering. An incredibly rare and unique opportunity to own a masterfully curated and fully custom-designed home in Baltimore County's newest and most coveted enclave, Castanea Estates. A collective collaboration between architectural firm GBL Custom Homes and Battaglia Builders, alongside interior design by Bobbi Nock Interiors, this breathtaking residence offers six bedrooms and seven and a half bathrooms throughout its 12,000 square feet of living space. Upon approach, natural stone envelops the exterior and gives an organic, modern, castle-like aesthetic. Timeless elegance welcomes you through the double-door arched entryway into a grand foyer with a demanding sun-drenched view, flanked by classic checkerboard flooring, stunning archways, and a double wrought-iron wrapped staircase. This home has been exquisitely appointed from top to bottom with various marbles, real hardwoods, Restoration Hardware, and Visual Comfort lighting, along with a stunning Cristallo quartzite backlit island countertop at the center of the chef's kitchen. A full-sized professional gym, wine room, butler's pantry, wet bar, his and her separate luxury primary suite bathrooms, and separate walk-in closets, and a resort-style custom pool and spa are just some of the incredible luxury amenities this home offers. The vast exterior living space features a beautiful al fresco dining area, BBQ grill, and multi-level covered seating areas. The impressive resort-style saltwater pool features waterfall gas fire bowls, tanning shelf, built-in bar stools, and a separate spa that can operate year-round, even when the pool is winterized.
