I would leave the building and just move the site plan or site mesh.
Otherwise it is turn on all the layers that you want to move (except the site layers) and use the bold (thick - all storey) marquee around the building and stretch it the 200mm.
Then go though all of your sections and elevations and adjust any 2D text. line work, fills etc., that you may have placed because those elements will not move with the model.
