This detailed Y-Y section drawing depicts a complete residential building assembly, showcasing the structural relationship between roof framing and foundation elements. The roof system features metal/aluminum shake roofing installed at a 33° slope, supported by 2″×2″ battens and 4″×2″ rafters spaced at 2′-0″ centers. The assembly includes a 6″×3″ ridge plate, heat insulation layer, and 1″ thick ceiling. The wall construction consists of brick walls with 6′-0″ high side and rear boundary walls noted for screening with brick/trellis combinations. Structural elements include 6″ RCC lintels, RCC tie beams, and a rubble foundation system. The foundation assembly shows a 4″ thick mass concrete layer above dry earth filling. Interior spaces identified include a bedroom (8′-0″ height) and dining area, with a glass roof above a timber deck area at grade level. The drawing reveals thoughtful integration of the roof drainage system with a concrete gutter detail that requires further detailing. The comprehensive section effectively communicates both structural requirements and spatial relationships, with particular attention to weatherproofing at the roof-wall junction.
