About This Build
12' X 20' Transom Dormer Workshop
240 square feet with transom windows pouring light across the workspace. That's what this 12X20 Transom Dormer offered - a workshop where you could actually see what you were doing without flipping on every light in the place.
White siding with white trim gives it that clean, farmhouse look. The black roof adds just enough contrast to keep it from blending into the background. At 12 by 20 feet, this is serious workshop territory - room for a full bench, wall-mounted tools, material storage, and a project in progress all at once.
This model sold, but transom dormer workshops are available for custom order. Same construction, same natural light, your choice of size and upgrades.
