Juliet Gray, Mathias Kolehmainen, and their sons Cooper and Cyrus have a new favorite hangout: the wide back steps on the addition, which double as theater seating. (They project movies from the second-floor balcony onto an out-building across the yard.)
The living room in the original house has Victorian details, but the furniture—vintage Bertoia chairs, a Gloss floor lamp by Pablo Pardo, and a Norm 03 Steel Pendant Lamp by Normann Copenhagen—brings the look up to date.
The family room has wall-to-wall cabinets built by Bradford T. Newhall Construction, a local company that also served as the general contractor on the project. The stainless steel drawer pulls are by Sugatsune. The minimalist white-and-wood interior complements the couple's collection of mod furniture, which includes a vintage sofa by Edward Wormley for Dunbar and two cork tables by Jasper Morrison for Moooi.
The cherry veneer cabinets carry into the streamlined kitchen where a Shepard Fairey print and a range by Wolf take pride of place. "We tried to make sure that all the wood used in the project looked seamless and uniform," says de Leon. "Wood was the only 'color' we introduced."
