He lived in Set Maat (translated as "The Place of Truth"), contemporary Deir el-Medina, on the west bank of the Nile, opposite Thebes.

When Sennedjem's tomb was found, it contained furniture from his home, including a stool and a bed, which he used when he was alive.

[3] Sennedjem was an ancient Egyptian official active in the early Nineteenth Dynasty during the reigns of the pharaohs Seti I and Ramesses II.

[4] He bore the title "servant in the Place of Truth" (sḏm ꜥš m s.t mꜣꜥ.t),[5] which indicates he was part of the community of royal tomb builders at Deir el-Medina.

Sennedjem and one or two of his sons lived in a cluster of houses in the newly built southern part of Deir el-Medina, close to the family tomb.

[24] The intact burial chamber of TT1 was discovered in January 1886 by Gurnawi local Salam Abu Duhi and three others.

They had obtained permission from Gaston Maspero, the director of the Antiquities Service, to look for tombs in Deir el-Medina.

After seven days of excavation, they found an intact burial shaft that led to a series of underground rooms.

[25] On 31 January Maspero was informed of the find, and visited with Urbain Bouriant, Eduardo Toda y Güell and Jan Herman Insinger on 1 February.
