Nebula

Plan Details

The Nebula is a versatile 400 sq ft studio ADU with 1 full bathroom, an open-concept living and sleeping area, full kitchen, and dual covered porches on the front and back. The open studio layout maximizes every square foot — the sleeping area, living space, and kitchen flow together seamlessly in a single bright, airy room. The compact 20' × 20' footprint (plus porches) makes it one of the easiest ADUs to site on any lot.

Key Features

• Open Studio Layout (20' × 20'): The main living space combines sleeping, living, and dining areas into one cohesive room. A king-size bed fits comfortably alongside a TV stand, open closet, and living area.
• Full Kitchen: Galley-style kitchen with full-size refrigerator, cooktop with range hood, and a breakfast bar with seating for 4. Open to the main living area for a connected feel.
• Full Bathroom: Complete bathroom with bathtub/shower, toilet, and vanity. Located in the upper-left corner for privacy from the main living space.
• Open Closet: Built-in open closet along the right wall provides wardrobe storage without taking up floor space with doors or walls.
• Washer/Dryer: Dedicated washer/dryer hookup tucked into the upper-right corner, accessible but out of sight.
• Front Porch (20' × 5'): Full-width covered front porch with double swing glass doors — perfect for outdoor seating and a welcoming entry.
• Back Porch (14'-9" × 4'-11"): Covered back porch off the kitchen area provides a second outdoor living space.

Why Choose the Nebula?

The Nebula is designed for homeowners who want maximum flexibility in the smallest footprint. At 400 sq ft, it keeps construction costs low while the dual-porch design makes the unit feel much larger than its square footage. The studio layout is ideal for a rental unit (studios are the most in-demand rental type in California), a guest suite, home office, or aging-in-place unit. The compact 20' × 20' footprint fits on nearly any lot with standard setbacks.

Customization and Modifications

The Nebula plan can be customized to fit your property. Options include mirroring the layout, adding a partition wall for a separate bedroom, modifying the kitchen configuration, or enclosing one of the porches. Full architectural plans include elevations, axonometric views, door and window schedules, and 3D entrance/back porch renderings. Our team will tailor the plan to your lot and local codes.
