Plan Smarter with 3D Design - Visualize Your Future ADU Before You Build Pre-construction 3D ADU service

A woman with long hair is standing in front of a kitchen counter, smiling at the camera. She has on a denim vest over a white top, blue jeans, and a pair of sunglasses is placed on her head.

Dedicated project designer

From start to finish, you’ll work one-on-one with a dedicated 3D Architectural Designer—your single point of contact throughout the entire design journey. They’ll help reimagine your layout, guide you in selecting finishes, and seamlessly manage updates along the way. Once your 3D design is finalized, they’ll personally coordinate with your chosen contractor to ensure a smooth handoff and confident start to construction.

Project layouts

We begin by understanding how you plan to use your ADU — as a guest suite, rental unit, or family extension. Then we develop a layout that meets your needs while staying compliant with local regulations.
