The proposed exterior pairs crisp white siding with stone accents, contrasting black windows, and a covered front entry for striking curb appeal.

Upstairs, the generous primary suite features a walk-in closet and private bathroom with double vanity, soaking tub, and separate shower. Three additional bedrooms and a full hall bathroom complete the second floor. A beautifully planned home combining timeless style, spacious gathering areas, and a versatile layout.
