Basically IMO it very much depends on what the goal of your model is. Are you looking at/for "whole building information" or do you want to go into detail? In the first case, probably modelling the whole building works fine. In the latter case, increasing detail for a whole building model could prove difficult. E.g. if detailed solar control is of interest, it may be enough to model the south-west part of the building. You mention a ground to sky shaft - I am not sure, what you mean, however, if something is to happen in the shaft, e.g. stack ventilation, then you will need to model it via thermal zones.
I (also) hope that helps.
