The houses have the walls made of white chalk and a thatched roof of straw daub and wheat, and are based on remains of such buildings found under a mile away at Durrington Walls.
Each house is made up of a single room around 5m across, with a fire at the centre with the smoke filtered up through the roof.
Susan Greaney, Senior Properties Historian at English Heritage, said:
“One of the things we’re trying to do at Stonehenge is to re-connect the ancient stones with the people that lived and worked in the surrounding landscape.
“Now visitors can step through the door of these houses and get a real sense of what everyday life might have been like when Stonehenge was built. These houses are the result of careful analysis of the archaeological evidence, educated guess work, and a lot of hard physical work.”
