Design a transparent flat roof structure to transform a 9-meter-long, 12-meter-wide outdoor walkway into a covered corridor. The walkway is located between a building with a basement and two stories on one side, and a wall approximately 1.5 stories high on the other. One end of the walkway leads to a dead-end with a door. The walkway consists of two levels: β’ The first level is 8 meters long. β’ The final 1 meter is lowered by 105 cm (β105 cm elevation change). The roof must be flat, but slightly inclined for drainage, sloping from the door side downward toward the opposite end of the walkway. The cover should: β’ Be fully transparent to preserve natural light β’ Protect against rain and snow β’ Use laminated tempered glass or UV-resistant polycarbonate panels β’ Include a powder-coated aluminum or galvanized steel frame β’ Accommodate the elevation change in the last meter of the walkway β’ Feature gutters and downspouts for drainage, with optional heated gutter system β’ Optionally include transparent side panels for wind and snow protection β’ Extend slightly beyond the door to create a small vestibule or canopy Also design a door at the opposite end of the walkway to allow through-access. Focus on clean aesthetics, structural integrity, and year-round weather protection while maintaining daylight access. Ensure the flat roof design integrates the two-level walkway and the slope direction from the door side. See more
