The goalis to get a level terrace with a railing.I propose building a level wood deck which sits on thepavement at the house, and is raised above the pavementat the front edge on legs which form the posts of theguard rail. the deck would restrain the guard rail postsso as not to need the pavement to resist the horizontalloads on the rail.60x80bi-passReplace original rear wing constructionwith new construction at the same buildingfootprint.3'-1 1/4"See "Fire Resistance Rated Assemblies" noteon Drawing A0a for descriptionof the construction of the fire rated assembliesused in this project.atticaccessProvide attic access (22" x 30" R.O.)as per R807.1 to reach all parts of attic spaceS2A3S1A3S3A3S5A3S2A3S1A3S3A3S5A360x80bi-passmicrefmicrefSee Stair Dimensionson drawing A0a.36" high handrail36" high handrail extends past windowto become 36" high guard rail at windowas per R312.1.36" high handrail
