Loji Gandrung was originally a residential house owned by Johannes Augustinus Dezentje (1797–1839). His father, August Jan Caspar, was a Dutch colonial military officer. Due to his family background, Dezentje had good relations both with the Dutch colonial government and the Surakarta Sultanate.

In 1815, Dezentje married Johanna Dorothea Boode, but she passed away in 1816 after giving birth to their first child. In 1819, Dezentje remarried to Raden Ayu Cokrokusumo, the sister of Sunan Pakubuwana IV. Through this marriage, he gained the right to lease 82 hectares of land in Ampel, which included 18 villages. By 1820, his plantation’s earnings were significant, reaching 5,000 Gulden per year.

According to SA Buddingh’s notes, when he visited Dezentje’s residence in Ampel, it was described as a landhuis in the traditional Javanese “dalem” style, complete with a yard, garden, gamelan entertainment, and a fortress area with bastions, troops, and weapons. This house later became known as Loji Gandrung.

The name Loji Gandrung came about because this place was often a venue for social gatherings of the European elite, which involved feasts, drinking, and dancing. These activities were similar to the concept of being "gandrung" or infatuated, a term used in traditional Javanese performing arts. Literally, loji refers to a colonial-style house, and gandrung means excessive pleasure or attraction.
Such parties became popular in the early 20th century, following the Dutch colonial government’s economic liberalization policies, which allowed foreign capital to flow into plantations and industries. It was likely during this time that the name Loji Gandrung began to be used, and the building's structure was modified into what we recognize today.
