In several embodiments, the disclosed process may include installing one or more householder devices onto load-bearing structures of a building, installing one or more perimeter beams onto the one or more householders, installing a new exterior assembly onto the one or more perimeter beams, removing an existing roof, and constructing an additional level on the building. In at least one embodiment, installing the one or more householders onto the load-bearing structure may include cutting a hole in the existing roof above the load-bearing structure, attaching the householder onto the load-bearing structure, and sealing the hole around the householder. In some embodiments, the new exterior assembly may be partially or fully constructed on site and may be installed onto the one or more perimeter beams. In some embodiments, once the new exterior assembly is installed, the old roof may be removed from underneath the new exterior assembly.

A system and method for raising a structure, or part thereof, the system comprising vertical jack members connected and disposed about a rail system attached about the periphery of the structure. The vertical jack members comprise an outer sleeve and a slidable inner portion that is driven vertically by a jack screw and drive block. Extensible diagonal cross-braces stabilize the jack members and structure being raised.
