The mark consists of two vertical, parallel bars with the bottom inside corners clipped at 45 degrees from the outside corner, at the top is a triangular symmetrical shape giving the overall shape of a basic "house" except with a gap cut in - same thickness as the bars - from the left, toward the right up until the same thickness from the right edge, which then follows up and diagonally to just under the roof of the "house" shape, before turning downward and ending flat horizontally against the other side from the inward cut. The resulting form is made up entirely of lines of roughly equal thickness, no solid-filled areas, negative space within the "roof" on top having the same thickness as the sidebars, and lines in the triangular shape on top.
