Maximize Space

Light and Ventilation

The importance of natural light and ventilation becomes even more apparent in the compact space of an ADU. Illuminating spaces with natural light breathe vibrancy into these smaller spaces while optimal airflow creates an airy atmosphere despite their placement adjacent to or behind primary residences. Abundant light and fresh air can fill ADUs through properly placed windows and skylights, giving it the feel of a larger space.

Many smart designs optimize efficiency by sharing plumbing and walls between kitchen and bathroom fixtures, minimizing waste.
