About this home

You will be impressed as you walk through the front door and enter the 18 foot high foyer with hanging chandelier, real wood flooring, oversized staircase, and open floor plan. To your left a combination living room / family room with many floor to ceiling windows, and a beautiful masonry fireplace. Continue your walk and enter the kitchen / breakfast room with two double glass doors facing the large and level private backyard, perfect for a swimming pool, playground equipment, or both. Upstairs around the open foyer are three large bedrooms with a loft that can easily be converted to a fourth bedroom (contractor bid $7,035). The enormous master bedroom features many windows, and two walk in closets. The master bathroom features a glass shower, and separate spa bathtub. The oversized garage can easily fit two cars, a golf cart, a Harley, and other toys. The rear entry garage design provides for additional driveway parking. All this on a quiet cul-de-sac. Welcome home!
