Grand Egyptian Museum

For this competition entry, the Great Museum becomes a signal calibrated to the sun, a way of engaging the Pyramids' own monumental, mysterious character rather than competing with it. The plan follows two perpendicular axes: one running north to south, mostly underground, carrying visitors directly from the entrance into the heart of the permanent collection; the other running east to west, linking every internal and external function of the complex together. At the centre of that layout sits a pentagon, chosen after testing the whole range of possible polygons for its adaptability and its symbolism alike. Geometrically, it maps cleanly onto the exhibition's own structure, five themes and nine periods, while echoing the golden ratio that underlies the construction of the Pyramids themselves; symbolically, its five-sided mystery feels suited to housing the museum's greatest holding, the treasure of Tutankhamun. Visitors reach the permanent halls along an underground route conceived as a journey down the Nile through Egyptian history, arriving beneath a glazed roof crowned by an elevated structure that protects, captures, and reflects the desert sun above. Secondary functions are folded into the surrounding dunes, stepping down with the site's own contours rather than sitting apart from them.
