AMESBURY, England — About 6,300 years ago, a tree here toppled over.

For the ancients in this part of southern England, it created a prime real estate opportunity — next to a spring and near attractive hunting grounds.

According to David Jacques, an archaeologist at the University of Buckingham, mud was pressed into the pulled-up roots, turning them into a wall. Nearby, a post was inserted into a hole, and that may have held up a roof of reeds or animal skin.

It was, he said, a house, one of the earliest in England.

Last month, in the latest excavation at a site known as Blick Mead, Mr. Jacques and his team dug a trench 40 feet long, 23 feet wide and 5 feet deep, examining this structure and its surroundings. They found a hearth with chunks of heat-cracked flint, pieces of bone, flakes of flint used for arrowheads and cutting tools, and ocher pods that may have been used as a pigment.

“There’s noise here,” Mr. Jacques said, imagining the goings-on in 4300 B.C. “There’s people here doing stuff. Just like us. Same kids and worries.”
