 Master plan and principal pavilions of the exhibition are credited personally to Pomerantsev.Most pavilions relied on novel steel frame load-bearing structures designed by Shukhov; they "represented the most advanced use of metal-frame construction for their time and possibly the first use of a metal membrane roof" (Shukhov Rotunda).Pomerantsev's "Pavilion of Arts" was based on traditional structure, but stylistically predated Charles Girault's Petit Palais (1900) and is considered the forerunner of emerging Russian Art Nouveau.
