ADU Testimonials

Don’t take our word for it. Read some of the things our past clients have said about working with us on their ADU project:

I can't share how much I am grateful for this team and the help they provided me with my project. From day one they have done everything possible to work with me to make sure that everything went as smoothly as possible. You guys have been awesome, thank you for everything.
- Benjamin E.

They’ve been great to work with as artists, as technicians, as resources, as problem solvers, and as people who genuinely cared about finding the right outcome for me.
- Monica V.

We hired Lucas to help us design an ADU in our backyard and couldn't be happier. Very professional team who cares about doing a good job and creating great projects. Would and have recommended to anyone looking for an ADU.
- Kiel J.

We are so glad that we worked with [Lucas] through the design and construction process of our new home. They were ever-helpful as we worked together through final land-use and permitting processes, and worked well with iBuildPdx to ensure the design meshed with practical construction considerations. Despite a daunting list of design constraints due to the rural, forestland property codes, [Lucas] created an incredible place to live that is just as comfortably "at home" in its environment as our family is in the house.
- Mark T.

It was a true pleasure working with [them] on a detached ADU project. I wanted to be as involved in the process as possible, so their team built a custom package of services that filled in the gaps and helped me get a building permit affordably. I highly recommend working with [them] on any type of design project.
- Mason W.

If you are considering using a firm to formulate a design while incorporating your ideas, they are a great investment. Not only are they full of fresh ideas but really take the time to listen to yours. All the employees are professional while still being authentically friendly. A joy to work with. I explained my taste for sleek, modern and minimalist and that is exactly what I got, a truly beautiful dwelling and yet somehow within my budget.
- Joanne R.

Making the most of Modern ADU Plans

ADUs are amazing projects and every backyard should have one. This is why we have tailored our designs to work in backyards across the US and Canada. However, small house plans like these have many other potential uses.

These ADU plans would make amazing cabins in the woods, vacation houses on the coast, or weekend getaways up in the mountains. ADUs can be used for a guest house or a pool house on larger properties. Perhaps you need a home office or art studio as part of a larger estate. ADU plans could be used for that too.

Many of our clients have worked with us to find the perfect Airbnb rental design, while others were looking for Aging-in-place ADU plans. We have even worked with a family to adapt one of our ADU designs to become a small home as their primary residence on a vacant lot they purchased.

Whether your goal is multi-generational living, downsizing to a smaller home and lifestyle, building a fully accessible home, starting a rental business, or growing your real estate investment portfolio, our affordable ADU plans are a versatile way to get started.

The opportunities are truly endless.
