The density of buildings in a city has affected the urban microclimate. The urban area gets hotter than the rural area. Characteristics of nature and climate need special attention. The design of the house determines the effect on indoor and outdoor thermal comfort. This research was conducted in two sub-districts or three urban villages in Banjarmasin. The sub-districts are Central Banjarmasin sub-district and the East Banjarmasin sub district. Results, Thermal comfort of Indonesian National Standard (SNI) 03-6572 in open space has a minimum and maximum effective temperature difference, between open space without vegetation and vegetation. Vegetation planted around the building has an effect on the buildings thermal environment. Vegetation around rivers and buildings can lower the average effective temperature by 0.7 O C ET. At a minimum, the effective temperature difference between green open space and open space without vegetation is 1 O C ET. The thermal comfort condition in open space without vegetation in uncomfortable condition while vegetated still in a comfortable zone. The indoor effective temperature has differences between riverside buildings and settlements are 1 O C ET. Conversely, at maximum effective temperature, open space without vegetation is higher than 2 O C ET compared to open space with vegetation. The thermal comfort condition in buildings with ventilation and ceiling are better, but the buildings with zinc material for the roof are hotter.
