About This Home

Exceptional former model ranch paired home showcasing premium upgrades and designer finishes throughout. The thoughtfully crafted floor plan features 2 main-floor bedrooms. The primary bedroom features a spacious bathroom that includes a walk-in shower. Through the bathroom you will find the impressive walk-in closet. The second bedroom is also an ensuite providing privacy and comfort. The kitchen is beautifully finished with quartz countertops, tile backsplash, stainless steel appliances and a large island. The kitchen, eating area and living room provide an open feel with plenty of natural light and views out the windows. This area also gives way to a secluded deck that looks out to the east and to the open space that surrounds the back of the property. The well designed walkout basement adds 2 additional bedrooms, one of which has its own bathroom with a walk-in shower and walk-in closet. The large living area in the basement, which includes a small sink, counter space and a gas fireplace, is ideal for entertaining or extended living arrangements. The finished lower level expands the living space while maintaining comfort and functionality. A rare opportunity to own a beautifully appointed, move-in-ready home with the convenience of low-maintenance living.
