3400 Sq Ft Craftsman House Plan with Optional Upper and Lower Levels

This thoughtfully designed one-story Craftsman plan spans about 3,377 sq ft on the main level and offers options to add upper and lower living spaces—boosting flexibility for growing families or future rental needs. The classic stone-accented facade and open lodge-style living area make it equal parts welcoming and functional.

Lodge Living & Smooth Flow

Step into the vaulted lodge room with a grand fireplace and wood-trimmed ceiling—it’s the kind of central space you want to gather in.

The seamless open-plan connects kitchen, dining, and living zones, helping family life move with ease. Sliding doors at the back open to a covered porch that transitions naturally to an open deck—perfect for indoor-outdoor living. 1

Master Retreat & Guest Flexibility

Downstairs, the optional lower level adds even more functional living space. 2
