Interior designer Kati Curtis helped distill Verhoeven’s thousands-of-pins-deep Pinterest board—“I had a very particular idea of what I wanted,” the homeowner says—into a viable plan. Curtis hunted down specific additions and uncovered fun pieces her client hadn’t seen before, like those for the daughters’ playful bedrooms. The art guru’s vision: warm and livable, a little fun and different, and not too formal or cookie-cutter.
