A lifting device (12) for lifting an upper portion of a building which comprises a roof (11) and a method of constructing a building using such a lifting device. The lifting device includes a base plate (13) arranged to be mounted to an edge region of a support (10) and a lifting platform (14) attached to an actuator (15) and capable of vertical movement by means of the actuator. The base plate has a first portion arranged to abut a substantially horizontal face (10a) of the support and a second portion arranged to abut a substantially vertical face (10b) of the support. The actuator is adjustably mounted to the base plate such that the position of the actuator is horizontally and/or vertically adjustable relative to the base plate to ensure a plumb lift.
