The gourmet chef's kitchen is beautifully appointed with custom wood cabinetry, granite countertops, Wolf energy-efficient appliances, Sub-Zero refrigeration, an oversized center island with prep sink and seating, a walk-in pantry, and a dedicated bar area. A stunning crescent-shaped bar with seating for ten and built-in beverage coolers further enhances the home's entertaining appeal. The main level also features a private guest suite and an office/bedroom.  Throughout the home,  20 built in indoor speakers controlled by a Sonos system creates the perfect atmosphere for gatherings both large and small. A sweeping staircase leads to the second level, where five spacious bedrooms await. The main primary bedroom includes an exceptional waterfront primary suite with a private balcony overlooking the bay, spa-inspired bath, and generous walk-in closets. Additional guest accommodations include a Jack-and-Jill suite, a bedroom with private bath, and a second primary waterfront suite with private bath access, creating ideal accommodations for family and guests. The third level offers a spectacular recreation room complete with television lounge, pool table, shuffleboard, half bath, and breathtaking panoramic water views, with access to elevated observation decks that capture both sunrise over the Atlantic and sunset over the bay. It is legitimately one of the best views in Bethany Beach with exceptional vantage points.  The lower level is equally impressive, featuring a fully equipped fitness room, multiple utility areas, tankless water heaters, extensive garage space, and more than 1,500 square feet of temperature-controlled storage. Dual laundry areas provide added convenience for large households with a laundry room on the lower and bedroom level floors.
