Jengki is one of the architectural styles that was developed and spread in
several regions of Indonesia between the 1950s and 1960s. Buildings with Jengki
architectural style have their own values and identity as part of the development of
authentic modern architecture in Indonesia. Until now, the existence of buildings with
Jengki architectural style still can be found in Indonesia, one of them is Yogyakarta.
But over time, the existence of buildings with Jengki style has changed because of
several interests. The Jengki buildings often to be abandoned, they become unmain�tained, damaged, or sold and then turned from residential into another function. This
condition also occurs in Jengki buildings in Yogyakarta. In this research, the authors
try to study the façade changes of Jengki buildings due to the function changes as
commercial buildings. Through the research, it is expected to be able to identify
which of the element on the facades of Jengki architectural style is still surviving,
change, or disappear, and also how far is it still recognized as a Jengki building.
This is qualitative-descriptive research with a purposive sampling technique. The
building samples categorized in Jengki architectural style, then analyzed based on
phenomena, especially in façades element which currently function as commercial
buildings. Based on the analysis, it was found that the changes in the façade elements
mostly occur in buildings that have functional change from the residential to commer�cial. The addition or changes in the façade element make the characteristic of the
Jengki architecture less visible.
