40x32 Feet House Roof Plan DWG with Galvanised Sheet Details

This AutoCAD DWG drawing presents a detailed roof plan of a 40x32 feet G Plus 1 residential house with complete roofing structure and material specifications. The drawing features galvanised aluminium longspan roofing sheets, timber rafters, timber purlins, timber bearers, ridge cap details, and roof eaves projections. Accurate spacing of rafters at 4 feet center to center and purlins at 3 feet 6 inches center to center is clearly illustrated for structural stability. Roof slope directions, drainage flow paths, junction connections, and ridge alignment are also properly marked to support effective rainwater management and long-term durability.

The residential building includes three housing units on the ground floor with functional spaces such as a living area, kitchen, an entrance lobby, a common water closet, a master bedroom with an attached bathroom, a guest room, a kids’ room, and a porch.
