At Foundation9 (FDN9), we take pride in crafting beautifully functional accessory dwelling units (ADUs) that blend seamlessly into your property while maximizing style and efficiency. Our collaborations with Cottage focus on delivering innovative, thoughtfully designed living spaces that meet diverse needs, from cozy retreats to multi-generational homes.

Each Cottage + FDN9 ADU project begins with a shared vision: creating a space that reflects your aesthetic preferences while addressing practical requirements like zoning, privacy, and functionality. With our combined expertise, we emphasize smart layouts, sustainable materials, and custom finishes, ensuring each project is a harmonious extension of your home and lifestyle.

From conception to completion, we bring a collaborative spirit to every project. Whether you're envisioning a private guest suite, a rental property, or a space for family members, our designs optimize limited square footage to create a living area that feels anything but small. The result is a blend of FDN9's refined design language and Cottage's innovative construction solutions, delivering ADUs that are as unique as their owners.

Cottage + FDN9 ADU Collaborations aim to inspire a new approach to modern living, where every detail matters. Together, we transform the concept of “extra space” into a meaningful part of your home’s story—beautiful, functional, and designed to last for generations.

Let us help you create the perfect ADU solution that embodies comfort, efficiency, and timeless design.
