Abstract: A prefabricated space module resting on a horizontal support surface is transferred using at least three elongate stands, each stand having a wheel at a first end and an engagement element at a second end. The engagement elements are adapted to engage respective attachment elements of the space module. Each stand is of a length such that a surface region of the wheel at the first end of the stand can engage the horizontal support surface when the stand is inclined to vertical and the engagement element at the second end of the stand is engaged with an attachment element of the space module. By displacing the first end of each stand toward a position in which the stand is more nearly vertical while the engagement elements remain engaged with the respective attachment elements, the space module is elevated clear of the horizontal support surface.
