3way House by Naf Architect & Design

In the crowded urban grid of Tokyo, Japan, the strategy for space is to build up instead of across. Naf Architect & Design takes this to an extreme with 3way House, and presents – as the name suggests – three ways of vertical ascension. Each of these methods, stairs, ladder, and rock wall, offers its own connection between spaces. The rock wall, perhaps the most formidable and fun with its colorful footholds, presents a journey across three floors from porch to rooftop. The ladder and stairs are lesser extremes but nevertheless offer an experiential understanding of the hobby room, sun room, and kitchen that branch off these paths. While 3way House throws convention, it enables interaction to highlight sectional circulatory richness within a residence.
