The Erso homestead, also called the Erso farm, was the home of the Erso family on the planet Lah'mu. The Ersos lived on Lah'mu for four years after escaping Coruscant before being found by Orson Krennic.
The Erso homestead was situated on sixty-five hectares of land on the planet Lah'mu. The land was purchased with the help of Onderonian rebel Saw Gerrera for the Ersos to use as a hiding place from the Galactic Empire. Most of the living space was subterranean, stark, and closed, with insulator drapes and chiller bars used to help regulate the temperature underground. The kitchen was modular and made of sturdy units to help prevent dry goods from being infested with vermin or insects. Shunts were inserted into geothermal vents to provide power and heat to the structure. Extra power was stored in converted supply tanks for emergency use and to power the homestead's moisture vaporators. Though water had to be collected using vaporators due to the high concentration of minerals in the ground water, the soil in the area was fertile and was used to grow crops—enough to sustain the family. The Ersos employed the use of an SE-2 worker droid to help with menial tasks as well as guarding the homestead.
