Architecture discipline principally has to deal with spatial boundaries, since once architects erect a building, that artificial object establishes certain dualities whether as its interior organization or its relationship to exterior surroundings. Each of these dualities imply certain division, separation or limits to space. Challenging these spatial boundaries through proposing innovative architectural concepts has been one of the major concerns for architects in recent decades. One of the figures who has a significant contribution to this subject is Sou Fujimoto, namely, his innovative architectural concepts which has been developed under the architectural project entitles as "Primitive Future". Nonetheless, certain spatial boundaries which has been blurred through his innovative architectural concepts in his works has remained relatively concealed. Thus, the aim of this qualitative documentary paper is to cast light on certain spatial boundaries which potentially can be blurred by Fujimoto’s innovative architectural concepts. In so doing, some of his remarkable works were investigated to make casual correspondence between blurred spatial boundaries and proposed architectural concepts. The required data has been collected through literature survey, mostly concentrated on primary sources produced by Fujimoto himself and the collected data have been analyzed by descriptive-analytic method. Findings demonstrated that certain spatial boundaries, namely established dualities between Architecture ─ Nature, Interior ─ Exterior, Architecture ─ Furniture, Object ─ Field, Figure ─ Ground, Public ─ Private, Architecture ─ City and Openness ─ Enclosure has been blurred in his works as a result of his innovative architectural concepts.
