The main front includes end stacks, with the gable of the crosswing projecting to the right. There is a porch located in the angle and a one-window range to the left. The left side has 6-pane horned sashes, with the upper sash breaking through the eaves beneath the slate-hung gable. The porch is made of timber and gabled. The crosswing has a 6-pane horned sash above and a tripartite 2-4-2-pane sash below. The south side also features a slate-hung upper floor and the chimney gable of the front range is located to the left, with a rear end stack.
