This project focuses on constructing a staircase with temporary support, later replaced by LVL stringers for added strength. It includes features like a two by four for rigidity and soundproofing with mineral wall insulation. Plywood treads and risers are installed, integrating plaster walls for a seamless look. Specialized carpentry is needed for the handrail, while LED tape uplighting enhances the atmosphere. Skylights provide natural light, and tile installation on angled walls requires clips for support.
