PROBLEM TO BE SOLVED: To provide a building structure constructed with log materials having the weight and length handleable by oneself. SOLUTION: Two columns of log members 1 are connected with log members 2 to form a wall, log members 3 are crossed in several stages to form cruciforms and connected to the log members 1 to form beams, and log members 4 are combined with the log members 1 in several stages to form a roof. All log members have the weight and length handleable by oneself, and this building structure having sufficient strength can be constructed by oneself by compositely combining them.
