Introducing the Dexter plan, a thoughtfully designed 2-story layout that adapts to your lifestyle. With 3-4 bedrooms, 2.5-3 bathrooms, den, and game room this  2,187—2,251 square feet home has plenty of space for everyone!

As you step onto the charming front porch, you'll enter a spacious foyer that offers a view all the way to the back of the home. You’ll pass a den and a half bath and the laundry room before arriving in the main living area. Looking for a secondary bedroom on your first floor, convert this space into your 4th bedroom and 3rd bathroom.

Whether you're hosting a laid-back weekend game night or a sophisticated holiday dinner party, the open-concept kitchen, dining area, and family room combine to provide the ideal ambiance for entertaining.

The kitchen includes granite countertops, stainless steel appliances, a working island ready for food prepping or entertaining, 42” cabinets that come in a variety of wood species, colors, and stains.

With a large sectional, comfortable chairs, a coffee table, and an area rug, arrange a functional family room you’ll love relaxing in each evening! Upgrade with the optional fireplace to enjoy those cold winter nights.

The covered patio is accessible from the family room for when you want to enjoy a nigh out enjoying the evening breeze. In this space you can also upgrade to add a 3-panel glass door slider an merge your outdoor and indoor living space seamlessly.

The luxurious owner's suite boasts abundant natural light, with the option to upgrade with a bay window, a walk-in closet, and an en-suite bath. To elevate your experience, consider selecting our deluxe bathroom option, which includes a tub and a walk-in shower.
