Abstract
Abstract A room addition type of construction for attachment to the outside wall of a building. The wall has an opening for access to the interior of the building. A foundation is provided adjacent the wall and an upright frame assembly is mounted on the foundation. The frame includes side wall frames, an outer wall frame, and a roof frame. A plurality of structurally independent panel members are securely mounted in each of the frame portions with a substantial portion of the panels comprising window units having glazing panels therein. The panel members cooperate with the frame assembly for providing load bearing support for the structure. The frame assembly is secured to the building and a weather seal is provided between the room structure assembly and the building. The panels are secured to each other and to the frame assembly and weather seals are provided between the panels and between the panels and the frame assembly.
