Types of Accessory Dwelling Units

Now, let's explore the diverse forms ADUs can take. From the quaint detached cottage nestled in your backyard to the artfully converted garage or an elegant addition seamlessly integrated into your existing home – the choices are as varied as your imagination. The architect’s role is to help you envision and realize the ADU that aligns perfectly with your needs and preferences.

The Enchanted Backyard Cottage

Imagine strolling through your lush backyard, surrounded by vibrant flora, and stumbling upon a charming cottage. This detached ADU is the epitome of fairytale living. With its own entrance, kitchen, and bathroom, the backyard cottage provides a secluded haven, perfect for guests or as a private retreat. As an architect, envisioning this cottage is like crafting a storybook escape right in your own backyard.
