A plank-type building system uses longitudinal splines and transverse tie bars to provide a solid wood wall building structure having increased structural rigidity. Planks having a longitudinal groove extending along each side surface of a plank are used to form the floor, walls, and roof of a building. The planks are connected together by a separate spline that is inserted into the grooves of adjacent planks. A transverse slot is formed on a main surface of each plank to receive a tie bar that prevents relative displacement of adjacent planks. The tie bar also prevents insect and element infiltration through gaps formed between adjacent planks.
