Design Build

Ballard Backyard Cottage's architectural design team works with you to design your dream DADU. Our architects and contractors work together as a team so you count on communication and cohesion throughout your ADU build.

We can also help you customize existing plans, adapt designs you’ve seen and liked, or tailor pre-approved plans to better suit your needs. If any modifications require additional city permitting, we’ll guide you through the process and coordinate with the city to ensure everything stays on track.
