This week’s ADU Case Study was written and contributed by Deborah Kelly, the owner of an ADU called Mossy Cobbles. Deborah worked with her son, Justin S. Kelly, who is an architect and engineer, to design the cottage for Deborah’s mother to occupy when she lived in Portland for half the year. It was constructed by the next door neighbor, Tony Kikes with hardscaping by another friend and neighbor, Steve Carruthers. The cottage is now available as a short-term rental.
Major design considerations for Natalie and Justin Strom included creating a feeling that their ADU is more like a single family home than an ADU and fitting the ADU into the aesthetic of the traditional neighborhood while bringing in modern elements in the interior. It was also important to Justin and Natalie that the design be flexible enough to allow for multiple use and that they utilize sustainable and energy efficient building materials and techniques.

The ADU was constructed in 2013 and the primary dwelling in 2015.

Ray Chirgwin first learned about accessory dwellings through his work as a licensed architect. He had familiarized himself with Portland’s zoning code, so he knew that ADUs are allowed by right in Portland and was familiar with their requirements. As Ray and Natalie explored design criteria for their ADU, they landed on a design that allowed them to have a living space above and a shop below.
To create their ADU, Lisa and Patrick tore their 2-car garage down completely and built from the ground up with a brand new foundation.

There are a handful of developers who are using ADUs as part of their toolkit to create unique housing options. Kristy Lakin is one of these developers. She is currently constructing Woodstock Gardents, a pocket community with three primary dwellings, each with its own ADU. Kristy explains that her interest in developing small housing options like these comes from an interest in creating additional housing without compromising neighborhood character.
She anticipated that once it was complete, the backyard cottage would serve as a guest space for visiting family. However, she decided to go through the process of converting the garage to an ADU officially so that she could keep her options open. She liked the flexibility of being able to rent out the little space.

Tom anticipates that his wee home will be move-in-ready by the end of 2014.

Paz and his business partner, Katharina Grad Steinmeyer, have recently completed three UDUs (a twist on the ADU acronym which stands for Urban Dwelling Unit). Their new design firm UDU Design LLC has been inspired by the small housing movement and the need for aging-in-place design.
As a builder, contractor, and cabinet maker, Caleb Bruce builds boxes for a living, but he has also developed a knack for out-of-the-box thinking. Here’s the story of how Caleb turned an existing house into a secondary dwelling (or an accessory dwelling as we call them in Portland, OR).

When Ellen’s new university professorship required relocation to Virginia, they had to make big decisions about their SE Portland property. They knew they wanted to ultimately return to their home in Portland and for the time-being they planned to return during academic breaks. It didn’t make sense to leave their beloved home vacant while they were gone. However, if they leased their property they would have no place to call home when they returned to Portland for the holidays. A little ADU solved the problem.
Jeff and Beth knew there was demand for accommodations in this desirable area, since they built a duplex next door in 2004. But the idea of a guesthouse didn’t come to them until they were halfway through the project.
Matt and Lissa were building a new home and realized that creating an apartment over the garage was a good opportunity to add extra living space. The ADU could generate rental income and create flexibility as their housing needs changed. For now the ADU serves as a rental, but it could eventually be a home for their special needs son if needed.
Jill’s little home includes salvaged materials, low-flow fixtures, three salvaged doors, no dryer, solar panels, a ductless heat pump, a Rheem water heater, rain garden, skylights, and Marmoleum floors. She also installed grid-tied solar panels on the ADU which cover electricity for her lights, appliances, and heating.
