A method for constructing an elevator into a destination location from a plurality of prefabricated elevator modules includes fabricating a plurality of elevator modules, in particular at a location apart from said destination location. The fabricating includes providing one or more module frames having a longitudinal axis; positioning one or more of the module frames in horizontally oriented position, wherein in the horizontally oriented position the longitudinal axis is horizontal; and while the one or more module frames are in the horizontal position, performing installation work on said one or more module frames. The method includes arranging the modules into the destination location on top of each other such that said modules are in a vertically oriented position.
