The settlement method used is the descriptive method used in the design based on analytical reasoning and empirical structural research, along with identifying things that support the method.

This rental office is expected to be good news for business actors, freelancers, and stakeholders in overcoming problems regarding the need for rental offices in the Medan Sunggal sub-district.
