557 Knoll Court Why settle for ordinary when you can own something truly exceptional? Built by AB Development, this stunning ultra-modern 5-bedroom, 4-bathroom new construction is a showcase of striking architecture, luxury finishes, and thoughtful design at every turn. From the moment you enter, you're greeted by sun-drenched open living spaces, soaring ceilings, oversized windows, and a seamless blend of modern elegance and everyday functionality. The designer chef's kitchen with natural gas cooking serves as the centerpiece of the home, while spa-inspired bathrooms, spacious bedrooms, and carefully curated finishes create a living experience that feels both sophisticated and inviting. Natural gas heating provides efficient year-round comfort, and the partial unfinished basement with outside entrance offers additional storage and future possibilities. Crafted with the quality, attention to detail, and innovative vision that AB Development is known for, this is more than just a new home-it's a statement of modern luxury and a rare opportunity to own a residence that stands apart from everything else on the market.
