I need to create a Saltbox style roof in my Chief Architect plan where I have a long pitch roof that slopes down, which creates a single story on one side, and two stories on the other. How can I create this?


A saltbox style roof can be generated using the automatic roof tools and the placement of walls. 

To create a basic salt box style of roof, follow these instructions

  1. First, launch your Chief Architect software program and start a new, blank plan using the Default template.

  2. Select Build> Wall> Straight Exterior Wall  and click and drag out 4 walls to create a basic 40' x 30' structure. 

  3. Use the Select Objects  tool to click on the left 30' wall and choose the Open Object  edit tool to display the Wall Specification dialog.

  4. Go to the Roof panel and place a check mark in the Full Gable Wall option. 

  5. Click OK to apply this change.

    Follow the same procedure to make the opposite wall a Full Gable Wall.

  6. Select Build> Floor> Build New Floor , choose to Derive new 2nd floor plan from 1st floor plan and hit OK.

  7. On the second story, follow the same procedure for setting the two vertical walls to Full Gable Walls.

  8. Move the top horizontal 40' wall in so that its distance from the opposing bottom horizontal wall goes from 30' down to 20' 

  9. With this wall still selected, click the Open Object  edit tool to display the Wall Specification dialog.

  10. Go to the Roof panel and place a check mark in the Knee Wall check box.  


    A knee wall's height is defined by the roof above, not the ceiling height. 

  11. If you are not using a template that already has the Auto Rebuild Roofs option checked, then you will need to select Build> Roof> Build Roof  , and place a check mark in the Build Roof Planes option. Click OK to see the changes reflect in your plan. 

  12. Take a 3D Camera  view to see the results.
