I need to create a carport. How can I create that in Home Designer?


Creating a carport, or outside structure which has a roof held up by columns instead of walls, is easy to create using the Room Divider tool (previously called the Invisible Wall tool).

To create a room using invisible walls

  1. First, launch your Home Designer software and Open  the plan in which you would like to create the carport.

  2. In order to specify a roof over an area, we need to create a completely enclosed room within our plan.

  3. Select Build> Walls> Room Divider  and click and drag out walls to completely enclose the area. 

    • In this example, as the back wall of the carport is created by the front part of the garage, we only needed to place three invisible walls to complete the rectangular room area

    We could also use a Railing and then specify each one that you place as Invisible on the General panel of their specification dialog.

  4. Once we have created a room, we can use the Select Objects  tool to select it, and click on the Open Object  edit tool to display the Room Specification dialog.

  5. Since our carport is not a traditional room requiring a floor, on the General panel of the Room Specification dialog, we will change the Room Type to a Slab.

  6. Select the Structure panel in the Room Specification dialog. 

    • Lower the Floor(C) Height to -11" so that it will be only an inch above the Terrain.

    • If you only want a roof, and do not wish to see the Ceiling displayed in your carport, uncheck the Ceiling Over This Room option. 

  7. Go to the Materials panel and set the appropriate asphalt or concrete material for the slab room's Floor Structure.

  8. Once you have finished making changes in this dialog, click the OK button to apply and close the Room Specification dialog.

Now we are ready to manually place the columns that will hold up the carport area.

To manually place columns

  1. Select View> Library Browser  to display this window.

    In Home Designer 2014 and prior, navigate to Library> Library Browser

  2. Navigate to Home Designer Core Catalogs> Architectural> Millwork> Columns.

  3. Depending on the type of column that you want, you may also want to look at the Shapes section of the Library Browser.

  4. Continue browsing the library until you locate the type of column  that you want to use, then select it, and click in plan view to place the column.

  5. Use the Select Objects  tool to select the column and click on the Open Object  edit tool to display the Millwork Specification dialog and change the Height, Width, Depth, and Floor to Bottom values for the column as well as the Materials that it has applied to it.

    You may also find it helpful to resize the column in a Camera  view.

  6. You can adjust position of the column once placed by using the Select Objects  tool to select the column, and use its center square Move  edit handle to move it in to place.

    If you have difficulty placing the column precisely where you want, hold down the Ctrl key on your keyboard while moving it to allow for unrestricted movement. 

  7. Once you have completed editing the first column, if the others will be identical to it, use the Select Objects  tool to select the column, and click on the Copy  edit tool.

  8. Click on the Sticky  edit tool to be able to paste multiple copies of the column without having to select Copy/Paste each time. 

    Note: The Sticky edit tool is only available in Home Designer 8.0 and newer.

  9. Click in plan to paste copies of the column until you have the appropriate number of copies.

  10. Use the Select Object  tool to move the columns into place.

  11. Take a Camera  view to see the results.
