This drawing presents four exterior elevations of a call center building featuring structural glazing curtain wall systems. The two-story structure has a ground floor (FFL 100.000) and first floor (FFL 104.000) with multiple roof heights culminating at 112.900. The façade showcases a combination of Type A clear glass curtain walls and Type B spandrel glass units, supplemented with stone cladding and exterior plaster finishes. Key architectural elements include a granite base (20mm thick), stainless steel handrails, and granite steps at entrances. The design incorporates multiple parapet heights (TOPR) at 109.200, 110.000, and 111.600, creating a visually dynamic roofline. The elevation drawing includes grid references (numbered 01-21 horizontally and A-Y vertically) for precise positioning of architectural elements, which is essential for coordinating with structural and MEP systems during construction.
