OGI is a minimalist residence located in Tokyo, Japan, designed by Hamazaki Koumuten Architects & Associates. The building is situated in an ultra-narrow five square meter plot. The staircase utilizes landings large enough to occupy a single space, maximizing the floor plan within. The kitchen is situated on one of these landings, and takes up the entire wall to allow for a gas stove and counter space. The landing above contains the bathroom and bathtub. Skylights allow for additional natural lighting to enter the space without compromise to privacy.
