About this House

The wonderful, two-story Rio Grande home features an open-concept layout that is ideal for most any lifestyle. Upon entry, you are met with a private study room, a walk-in utility room, a closet, and access to your two-car garage. If you need extra storage space to store holiday decorations, tools, or even another car, opt to tack on an additional five feet for a two-and a half car garage or a full three-car garage! You are soon met with the soul of the home - the massive family room with two-story ceilings serving as the perfect place for entertaining, as well as the conjoined kitchen and breakfast area providing optimal convenience. The kitchen is fully equipped with sleek granite countertops, flat-panel birch cabinets, and industry-leading appliances. If you desire more counterspace, you have the option of including a kitchen island or extra cabinets! The high bar in the kitchen is ideal for the kids to eat breakfast in the mornings, and opens up to the family room, full embracing the open-concept feel. For the outdoor enthusiast, this home has the option of a spacious extended covered patio in the backyard. Head across the kitchen where you will discover the convenient downstairs powder room, and the secluded master suite. Your master bathroom is complete with cultured marble countertops, the option for dual vanities, and a large walk-in closet. Upgrade the master bathroom by opting for a luxury bathtub with stand alone shower or a master super shower instead! Follow...
