Smart ADU Design in 400 Square Feet: Luxury Living in Sherman Oaks

Accessory Dwelling Units (ADUs) have become a smart solution for homeowners looking to add functional living space without sacrificing quality or comfort. This 400-square-foot ADU in Sherman Oaks proves that thoughtful planning and intentional design can create a space that feels elevated, spacious, and fully livable.

Designed to complement the main residence, this ADU delivers the experience of a small luxury home while maintaining efficiency and simplicity.

A High-End ADU Built with Purpose

From the start, the goal of this ADU was to create a space that felt more refined than a typical secondary unit. Although it does not connect internally to the main house, the ADU was designed to carry the same design language and level of detail. The result is a self-contained living space that feels intentional, private, and well-integrated into the property.

Maximizing Space Through Smart Layout Design

Every square foot of this 400-square-foot ADU was carefully planned to ensure comfort and usability.

Functional Layout Features

  • One-bedroom configuration
  • One full bathroom
  • Fully functioning kitchen with all appliances
  • Living room designed for daily use
  • Washer and dryer area located inside the bathroom

This efficient layout allows the space to function as a complete home rather than a temporary or limited-use unit.

Natural Light That Expands the Space

A major factor in making this ADU feel open and elevated is the strategic use of natural light.

Window Placement Strategy

  • Large windows in the living room
  • A window in the kitchen
  • A window in the bedroom

These openings bring in abundant daylight, visually expanding the interior and creating a bright, welcoming environment throughout the day.

Design Consistency with the Main Residence

Although the ADU is a separate structure, it maintains strong visual continuity with the primary home.

Design elements include:

  • Soft natural wood finishes
  • Neutral color tones
  • Clean, modern lines
  • A Mediterranean-inspired aesthetic

This consistency ensures that the ADU feels like an intentional extension of the property rather than an add-on.

A Fully Equipped Kitchen in a Compact Space

The ADU kitchen was designed to be fully functional without overwhelming the space.

Key features include:

  • Full-size appliances
  • Efficient cabinetry layout
  • Practical counter space for everyday cooking

By prioritizing usability and clean design, the kitchen supports daily living while maintaining a streamlined appearance.

A Bathroom Designed for Efficiency

The bathroom remodel was planned to serve multiple purposes without compromising comfort.

Bathroom features include:

  • Full bath
  • Integrated washer and dryer area
  • Efficient layout that maximizes available space

This smart integration supports daily routines while preserving the overall flow of the ADU.

Private Outdoor Space for Added Comfort

Beyond the interior, the ADU includes a private outdoor seating area, enhancing the living experience.

Outdoor Features

  • Dedicated seating space
  • Surrounded by ficus plants for privacy
  • Separate, plant-lined entrance

This outdoor area adds another functional zone, making the ADU feel more expansive and self-contained.

Elevated Living in Just 400 Square Feet

What sets this ADU apart is not just its layout, but how it feels. Through smart planning, abundant natural light, and consistent design choices, the space delivers a sense of comfort and luxury typically associated with much larger homes.

The ADU truly feels like:

  • A small house rather than a secondary unit
  • A private retreat within the property
  • A thoughtfully designed living space built for long-term use

Planning That Supports Precision and Quality

As with the main residence, every ADU detail was finalized before construction began. This approach allowed:

  • Clear execution during the build
  • Efficient use of space
  • High-quality finishes without unnecessary revisions

This level of preparation played a key role in maintaining quality while keeping the project on schedule.
