Two-and-a-half-year-old Aidan is a rough and tumble little boy who is always on the move and little sister Ella is always nipping at her brother’s heels. Mom and Dad are California transplants who've recently resettled in Virginia. They want to bring a little bit of that California hip and cool vibe to the kid’s space. The challenge: an all-white room with a vaulted ceiling and skylights that opens right off the living room. Designer Kevin has the right touch to mix toys and trains with music and mod for the perfect makeover cocktail.
