Thanks — your design is on its way to us. Here's the full spec; spin the 3D building on the left, and grab the image, plan or spec below to keep a copy.
What's it for?
Pick the closest fit — it sets smart starting points you can change.
Size
Roof
Roof only drops the walls — posts and roof, like a loafing shed or equipment cover.
Higher pitch sheds more snow and adds attic room. Pitches above 5/12 are custom and tend to cost more.
Raise or lower the clerestory (2–6 ft tall) for the raised-center windows.
How far the eave projects past the walls. Typical is 1 ft; custom up to 3'6". The gable (rake) overhang stays at ~1 ft.
Walls & siding
Press the button, then click a wall in the preview to open it — leaves the posts and roof, removes the siding and girts. Click it again to close it. Works with a wing: click the shared wall to open between the two.
Doors & windows
Pick a type and a size, then click the wall in the preview to drop it where you want. Spin the building to reach the other walls. Drag a placed opening along its wall to move it; select it and press Delete (or use the Delete button) to remove it.
Roof-only (open) building — no walls to hang doors or windows on. Switch Building back to “Enclosed” in the Roof step to add them.
Additions
Add a lean-to / porch cover, an enclosed wing, or a dormer — then click the wall to attach it. Set its size below, and drag it along the wall in the preview to position it.
Attached building
A full perpendicular building section with its own gable roof — its eave defaults to your building's height and can be changed.
