This pitched roof house by Japanese architecture firm On Design has a long and lean design, standing out for its height and oddly appealing dimensions. Dotting an extreme roofline, this vertical house boasts different-sized windows and openings, adding a whimsical aesthetic – traditional glazed windows or open cut-outs that accommodate trees growing along the hillside and piercing through the roof itself. Interiors echo the home’s ultra-angular silhouette, featuring slanted walls and lots of natural light. For more Japanese house designs visit On Design.
