There is a handsome powder bath off of the front foyer with silk wallpaper, impressive textures and colors to impress all visitors. Once theyve taken their seats under the soaring living room ceilings accented by exposed iron beams, theyll feel warm and comfortable by the fireplace. Those who want to chat quietly or sit close can find a spot in the adjoining family room, which is near enough to stay in the mix of things but separate enough to not be disturbed. A built-in dry bar and wine fridge is close at hand, as well. When hunger strikes, head to the beautiful-yet-functional kitchen energized by a fiery tile backsplash and sleek European-style bulthaup cabinets. Its lined with drawers and nooks so you can enjoy a sleek, minimal aesthetic every day and still have everything you need to cook a full-course meal within easy reach. With two sinks, a professional six-burner Wolf range and a separate prep and laundry area, your guests will take the ample space as an invitation to roll up their sleeves and help. Once everyone has had his or her fill in the casual dining area next to a toasty fire, take the party outside to the fire pit or relax on the recently updated and beautifully maintained deck while the grown-ups talk and the kids enjoy the playhouse. Need a sec to respond to an email? Duck inside, head past the second powder bath with eye-catching terrazzo tile and pop into the home office to type your reply. Youll be back outside and enjoying the party before anyone even knows you were gone. When the evening winds down, invite your guests to spend the night by offering them either the two-bedroom suite with an adjoining living area and two en suite baths, or set up their accommodations in the separate quarters behind the main house.
