Designed for the fifth child, an avid sports and Lego enthusiast whose favorite colors are blue and red. The palette runs through red-based table lamps, navy blue corduroy ottomans at the foot of the bed, and a geometric wool rug grounded in rust and navy on a neutral field, with a tree tucked into the corner at his request. A bedroom that takes a young boy's interests as seriously as the architecture that holds them.
