row, however, like the Minangkabau the front gable faces the neighbouring house's rear gable. The Karo and the Pakpak do not lay their houses out in streets but around a village focal points such as the meeting hall (bale) or rice pounding house (lesung). Toba architecture Batak Toba culture centres on Lake Toba and the sacred island of Samosir that lies within it. Jabu is the Toba language word for rumah adat. The houses are made up of three sections. A substructure of large wooden pillars resting on flat stones (or concrete nowadays) protects the structure from rising damp. Some of these pillars support longitudinal beams known as labe-labe, which run the length of the house at head height to carry the massive roof. Other pillars carry two large beams with carved singa heads which, with two lateral beams mortised into them, form a great ring beam bearing the small living area. The substructure is strengthened by beams mortised into the piles which double as night stalls for cattle. Walls are lightweight and lean outwards and provide additional stability to the structure. The wall and the wall plate supporting the rafters hang from the labe-labe with rattan cord, while the base of the wall sits on the ring beam. The rafters spring from the wall plate and are angled outwards producing the roof curve. In lieu of horizontal bracing battens, diagonal ties—running from the middle of the labe-labe to the gable ends—provide reinforcement. The large steeply-pitched saddle back roof dominates the structure. The roofs are traditionally thatched, and with no internal roof trusses they provide a large internal space. Sharply projected triangular eaves and gables overlap all around the substructure. The front gable extends further than the rear gable and is finely carved and painted with motifs of suns, starts, cockerels, and geometric motifs in red, white, and black. The rear gable remains plain. The living area, which is supported by lateral and transverse beams, is small and dark. Light enters through a small window in each of the four sides. The inhabitants spend most of their time outdoors and the house is largely used for sleeping. An attic space is provided by a flat wooden ceiling over the front third of the living area. Family heirlooms and sometimes shrines are stored here. Traditionally, the Toba Batak would cook over a hearth at the front of the living room making
