Custom built in 2012, the 18.99 acre property was lovingly conceptualized with multi-generational living in mind. The single story main residence is 3840 SF,3 bedrooms,3 bathrooms, and dedicated office space. Throughout the home, quality was never spared. High end finishes and appliances are appointed in every room of this beautiful home. Indoor living is both cozy and luxurious with travertine floors, solid wood trim, uniquely finished 10-12ft ceilings, hand plastered walls, chef's kitchen, and so much more! The professional landscaping is bursting with colorful foliage, a beautiful waterfall feature and sunken swim spa with deck surround. Entertaining is a blast with the built-in A/V smart system, bonus room with bar, gas fire pit and built-in outdoor kitchen with BBQ grill. Find peace of mind knowing that you have a GENERAC home generator back up power source (installed 2023) water softener system and gated entry on your private road. Positioned on the middle portion of the property you will find a detached fully finished, 2-bedroom in-law unit with full kitchen, laundry, double-vanity bathroom perfect for grandparents, college kids, or as income property. The ADU is conjoined with an extra large garage/workshop w/ 40-ft+ RV garage! Got an RV or boat? Got both? No problem
