 Attempts at achieving a uniformity in architecture was furthered by the introduction of standard "model plans".These were first introduced with the restructuring of the army by Charles XI already in 1682, whereby each of the lands of Sweden were to have 1200 soldiers at disposal, at all times, and two farms were to provide accommodations for one soldier.The "model plans" for military quarters, showing detailed facades and a scale, were designed in a classical Hårleman Rococo style or "Palladian" style, and these in turn affected vernacular architecture, in much the same way as the "model drawings" of the 16th century treatise by Palladio, "I quattro libri dell'architettura", influenced the following generations throughout Europe and in the colonies.
