“It was a brief stint in a 1987 VW Camper during University, while searching for permanent student housing. The experience validated my desire for a consistent, immoveable, place to call home, and that I wasn’t cut out for a vagabond lifestyle”

Most interesting home you’ve lived in?

“The aluminum thatched roof house in the Vietnamese fishing town where I grew up. There was no regular electricity, running water, or paved roads. My fondest memories are during the monsoon season, falling asleep to the sound of heavy rains pouring on the aluminum roof and waking up to fish swimming into my living room from the overflowing creek next door. “

“The 4600 square foot home I renovated in Washington D.C. We bought a 1908 row house that was a so run down, there was not much of the original structure that I could save. Over a course of 12 years, I rebuilt the whole house, from pouring the foundation and repointing bricks, to installing solar panels on the roof, offsetting 75% of the electricity in the house using 40% recycled materials.”

“A 2 level 1800 square foot floating home in Portland, Oregon. The house was originally designed by an architect in 1961. Very well thought out spaces but very dated materials. I spent a few years updating, including installing a unique roof that helped with the overall structure of the house. I had my boat parked in front of my house, so had access to the water year round. I even went to the grocery store by boat. There was a tremendous sense of community because everyone depended on each other to maintain the floating neighborhood. There were unique challenges in maintaining the house, mostly storm related, but a very wonderful lifestyle.”

Most interesting home you’ve lived in?

In 1991 I lived in a “granny flat” on the edge of a cliff in Haitaitai (Wellington) New Zealand. The cozy 200 m2 flat had a “million dollar” view of Evan’s bay in the Summer and terrifying Winter gales that rattled the whole house. In January, I loved to watch the Inter-island ferry set out for the South Island from a big picture window in the lounge but there were some August nights when the gale rattling off that same window and lifting the flat created a bit of terror.”
