modern glass storefront 3d model

Create a precise, realistic 3D model of a modern security checkpoint building (KPP) used at a school campus in Russia. IMPORTANT: generate a functional checkpoint, not a house, not a kiosk, not a futuristic pod. Overall shape: – One-story rectangular building. – Flat, box-like volume with strict geometry. – Sloped metal roof, 8–12 degrees. – Front façade must have a large panoramic glass wall (full-width glazing). Entrance and canopy: – A wide steel canopy above the entrance, reinforced and rectangular. – The canopy must extend outward and must be supported by metal beams. – Snow guards on the roof above the canopy. Materials (mandatory): – Fiber-cement facade panels in light grey. – Metal cassette panels in graphite grey (RAL 7012). – Corporate accent color: Gazprom blue (RAL 5017). Use it for a few façade details or vertical strips. – Large tempered glass panels with aluminum frames. Functional elements (must be included in the 3D model): – 4 waist-height turnstiles in front of the panoramic glass wall
