A modular building structure for converting an existing building interior to a convenience store or the like comprises a grid made up of a first set of parallel metal tubes supportable by levelers on an existing floor, and a second set of parallel metal tubes supported on, and extending orthogonally to, the tubes of the first set. Rectangular metal floor panels are supported on the grid. The panels have aprons along two opposite edges for resting on tubes of the first set, and the other two edges rest on tubes of the second set. The grid tubes are engaged with feet extending horizontally from upright, wall-panel supporting posts. The feet are identical and each is adapted to receive and support grid tubes of either set.
