The invention relates to a device 1 comprising a frame 2 having at least two surfaces arranged substantially perpendicular to each other, and at least one level indicator 3, preferably a spirit level, attached to the frame. At least a portion of the device with the at least one level indicator attached, is adapted to be fixed to a building element. Later embodiments relate to a method of constructing a building, wherein the device is fixed to a prefabricated building unit (7 figure 3), a prefabricated unit with the device fixed to the unit, and a disposable tool comprising a length of rigid material with the device fixed to the material. The device can be particularly useful in the erection of buildings using prefabricated building units such as studwork and the like. |
