Exceptional elegance on over 3 acres of private paradise! This home is simply majestic! Words don’t do it justice. From the Travertine floors to the 4 fireplaces… this home invites you in & makes you want to stay! The kitchen is a “cooks” kitchen with a Subzero fridge & a Wolf gas range! Lots of cabinets & countertop space to spread out, cook & entertain! The LL is simply awesome with a magnificent wet bar, custom wine cellar, and a home theater that will make you think you are “at the movies”!! Outside you will find fantastic stone retaining walls that look like “giants” built them! The attention to detail in the stamped concrete accents to the thoughtful landscaping & the stunning front door… it is evident in all aspects of this home! Once you come in, you don’t want to leave! The office/den is full of beautiful woodwork and trim… old school elegance! Something to be proud of for sure! The main floor primary bedroom is everything you could want! oh yeah… a 5-car garage! Additional Rooms: Wine Cellar
