This 600 sq ft one-bedroom ADU provides a dedicated sleeping area within a compact detached living space. The separate bedroom offers more privacy than a studio arrangement, while the full bathroom and in-unit washer and dryer make everyday routines more convenient. With its straightforward layout and practical amenities, this design provides the essentials for independent living without requiring a large building footprint.
At 24' × 25', this plan has a nearly square footprint that can be easier to accommodate on some properties than a longer, narrower design. The gable roof gives the exterior a familiar residential appearance, while the simple roofline complements the compact structure.
