Abstract: Simulated log corner units for constructing log cabin type structures from preformed log siding, which units are arranged on a foundation at the corners thereof and each include a vertically disposed beam to which a series of relatively short alternately arranged log end pieces are offsettedly attached so as to alternately project forwardly and laterally therefrom at right angles to each other at each corner and simulate the ends of the siding logs so as to be compatible with the log type siding applied to the exterior walls of the structure and the latter will have the appearance of a conventionally erected log cabin.
