Laura Lee Clark Falconer outfits a newly constructed, Frank Welch-designed home for Peter and Lael Brodsky. Working closely with Lael on the interiors, Falconer flawlessly executed the couple’s vision. The resulting mix mimics the architecture: a muted palette with pops of surprise. Under a curvaceous staircase is an unmissable Dror Peacock Chair in bold blue. Over the soft beige banquette in the first-floor library is a vibrant quintet of bright-blue John Zinsser paintings.
