“The most sustainable building is the one that’s been around the longest; something that will have value for generations. It’s designing something that nobody’s going to tear down; that’s where the longevity story is really important.” — Trevor William Lewis, W/K Partner, Western Art & Architecture
That idea shapes how we approach every project, and Royal II is one place we’ve put it into practice. The house steps down a steep slope overlooking Portland’s Forest Park, built from a simple palette of dark steel, concrete, glass, and a custom bronze-black cladding that sits quietly among the Douglas firs. A green roof wraps the house, and a filtration planter built into the concrete retaining wall is part of its water reuse system. Inside, white oak floors and neutral walls keep the focus on the woods outside.
We hope it’s a house that has earned its place on the hill for generations to come.
