meet the team

We believe that design and technology have a massive transformative power to advance the way we LIVE, the way we EVOLVE and the way we INTERACT with our built and natural environment.

Our team works one-on-one with home owners from start to finish: developing site plans, and designing units to make sure they fulfill user needs such as privacy/independence and green space, for the over all integration of the unit on the property.















As a company, we see our role as fundamental to bringing clarity and ease to the development process to allow homeowners to benefit from the full potential that their properties offer.

what is an ADU?

An accessory dwelling unit, usually just called an ADU, is a secondary housing unit on a single-family residential lot. There are different types of ADUs. Here at OASYS, we specialize in:

  1. Free-standing new construction sometimes called “granny flats” or “laneway houses”

  2. Garage Replacement construction known as Junior ADUs or JADUs because they are generally 400 sq. ft or smaller.

  3. Home extension or additions known as “bump-out” ADUs that are attached to the existing single family home


why get an ADU?

Our clients are adding ADUs to their properties for so many different reasons, the most common being:

- growing families

- passive income

- live-work space

- multi-generational living

"We're building an ADU for my 70 year-old mother to age in place"

- Tiffany L. , Los Angeles, CA

"Our plan is to rent out the ADU,

we want to retire early"

- James and Lily M. , Los Angeles, CA

From a community perspective, a significant increase in housing supply unfolds a closer-knit urban fabric advancing community values and reducing the environmental cost of growing communities
