About This Plan

This 500 sq ft studio is designed to provide comfortable, self-contained living within a compact footprint. Its studio layout creates a flexible space that can accommodate everyday living, sleeping, and dining, while the full bathroom and in-unit washer and dryer provide practical conveniences. The covered front porch adds an outdoor area for relaxing and enjoying additional living space beyond the interior.

At 25' × 20', this plan offers a simple rectangular footprint with a little more space than a smaller studio design. The shed roof gives the exterior a clean, contemporary appearance and creates a distinctive roofline for this detached ADU.
