A multi-floor building construction system for progressively constructing floors on load-bearing means of a foundation as the occupational need to do so arises and while sub-floors can be occupied. A permanent roof structure is displaceably supported over an uppermost floor of at least an upper one of one or more occupational floor spaces. Extensible load support means is secured in the roof structure until the completion of the mufti-floor building. The extensible load support means rests upon the uppermost floor to support the total load of the permanent roof structure. The extensible load support means is extendible downwardly to push against the uppermost floor to raise the permanent roof structure. Adjustable hoisting means is secured inside the permanent roof structure for lifting floor sub-assemblies fabricated in the construction zone using the extensible load support means while simultaneously raising the permanent roof structure.
