The archaeological excavations carried out at Lepenski Vir have led to the discovery of architecture of the people who were once settled in the area. More particularly, seven stages have been discovered in the constructions encompassing 136 buildings. These houses were found to have a standard design, although their sizes varied. The larger houses were found to be about 320 square feet and the smallest were 16 square feet. These houses were of two types: one that appeared to be used for households and the other that seemed to be a shrine or temple.

The accuracy of the geometry in these constructions are amazing, and has led to the insinuation that the period may have been the beginning of modern architecture. Although the houses have a trapezoid base which may have been copied from the trapezoid shape of the mountains, the base structures are accurately 60 degrees in measurement, and its construction takes the form of an equilateral triangle. Additionally, the tip of this trapezoid point towards the direction of the wind.

The material used in the construction of the walls is wood, and is constructed to take the shape of a horseshoe. The wood mentioned here may not have been proper wood, but wattle. Although there is evidence to support the fact that the houses had a rooftop, they may have been constructed using degradable materials and as such, cannot be distinguished. However, as it pertains to the interior finishing, the floors were found to be finished with something that sticks like concrete. It is believed that the substance is a mixture of red clay-lime, ash and animal dung which hardens over time. The evidence of the use of these materials in the construction of these houses comes from their availability and their present usage in the villages that surround the Lepenski Vir area.
