About this home

In an established neighborhood is this large contemporary home with gorgeous colorful landscaping. Inside, brand-new gleaming wood floors flow across the floorplan. The living room is centered around the fireplace and the media family room features bay windows. Centered in the home is the extra-large dining room and an adjacent eat-in kitchen, with long stone counters, wood cabinetry, high-end stainless-steel appliances. The island with bar seating is the social spot, and glass doors to the huge back offer indoor-outdoor flow. The lower level includes three bedrooms—one with full ensuite bath—and an additional second full bath. Upstairs is the coveted primary suite, with a full bath and space for an office and large walk-in closet. Out back, colorful trees and flora over a trickling creek join like a natural mosaic. Magical! Attached to the garage is a studio—great guest space or a home office. 18636 Sandy is a wonderful home in a desirable location.
