The house of Batak Toba, 'Rumah Bolon', is of a rectangle shape and is usually inhabited by 5 to 6 families. To enter the house, they must climb up a ladder which is located in the middle and has an odd number of steps. When someone wants to enter the house, he or she has to stoop so as not to hit the horizontal block. This act of bowing is meant as a guest respecting the owner of the house. This ethnical house, which is used for gathering and working, looks like a cow because it is originally inspired by a cow for its strong characteristic. The dining chair is simple, without decorative ornament but still reflects the culture of Batak Toba.
