The establishment of the Faculty of Landscape Architecture and Environmental Technology (FALTL) began with the establishment of the Academy of Gardening Architecture (AKAP), on the initiative of the Governor of KDH-DCI Greater Jakarta, which in 1970 was handed over to the Trisakti Foundation to be managed and fostered. In 1974 the Trisakti AKAP was upgraded to the Trisakti Gardens Architecture College (STAPI), with a length of education from 3.5 years to 5 years.

In 1977, by the policies of the Foundation and the University, the Faculty of Landscape Architecture (FAL) was established, with one department/study program, namely the Department of Landscape Architecture, as a substitute for STAPI. In 1985, the Faculty of Landscape Architecture (FAL) developed into the Faculty of Landscape Architecture and Environmental Technology (FALTL) with a new undergraduate study program, namely the Department of Environmental Engineering. Then in 1996, the faculty was opened Urban and Regional Planning study program. The three study programs have been nationally accredited, and the environmental engineering study program has been internationally accredited, namely IABEE and AUN-QA.
