Miramar, our design for a residence in Pacific Palisades, features limestone walls chosen for fire resistance as much as their texture, alongside teak accents at the doors and built-ins and terracotta at the fireplace surround. The L-shaped plan stays low to the land, opening onto terraces and reflecting pools where interior and landscape start to blur.

A favorite moment in the landscaping of our Hood River Residence project. The approach to the lower entry takes you through a grove of aspens planted beneath the main bridge. At ground level, the trunks, boulders, and native grasses form a privacy screen between the path and the adjacent guest room terraces. The canopy reaches clear up to the bridge deck above, uniting the two levels and creating a completely different experience when you enter at the street. We can’t wait to see how this continues to fill in as the trees mature.

We’re proud to be featured in Forbes this week as part of their America’s Top Architects series.

W/K partner Daniel Kaven spoke with Deputy Editor Fred Albert about Skyview, our four-story residence on a tight corner lot in Northwest Portland.

This is an example of a project where some of the most satisying solutions came from leaning into the site’s constraints rather than resisting them. The lot was narrow, the setbacks were strict, and our clients were coming from a much more expansive property in a wooded area. So we decided to flip the conventional residential stack, placing the main living areas and much of the landscaping at the top, 30 feet above the noise and power lines of the street below.

“For more than two decades, Oregon’s William / Kaven Architecture has made a name for itself designing tranquil glass-walled houses that are so immersed in their setting that it’s hard to tell where the home ends and the natural world begins.”
