However, to achieve true architecture, one still needed to elevate 'building' to 'building-art'.26 This artistic component regarded mainly the 'form' the visible, external appearance of the building - which matured during the final stages of the design process, following the resolution and consolidation of more essential, underlying factors, such as the construction.27 Indeed, the form depended on the essence of the building because, to be true, the form should clearly express this essence the building as it really was; being shaped out of its means and purpose.28 Through construction, the form could.
