I am building a house, or doing a remodel, and need to place a window well for an egress into my design. How can I model this in my Home Designer software?

Creating a window well with Home Designer is quick and easy


An egress is easy to create in Home Designer by creating a hole in the terrain and placing walls around the area.

In this article, we will walk you through the steps to create an an opening in your terrain and create an egress window. This article assumes that you have already created a foundation level, or Floor 0 in your plan, and have an existing Terrain Perimeter on Floor 1.

Note: Check the code regulations for your particular area on the necessary dimensions for the window and egress opening.

To create a window well for an egress

  1. Select Edit> Default Settings from the menu. 

  2. Select Foundation and click the Edit button.

  3. If you do not already have a foundation in this plan, select Build> Floor> Build Foundation to generate a foundation under your structure. For more information on creating foundation types such as basements please see the Foundations category of the Knowledgebase.

  4. Uncheck the Automatically Rebuild Foundation option and click OK.

  5. Move down to Floor 0 and select Build> Wall> Straight Exterior Wall and draw a room on the outside the basement walls.

  6. Using the Select Objects tool, select the new room and click the Open Object edit button to open the Room Specification dialog.

    • On the General panel, set the Room Type to Slab.

    • At this stage you can also uncheck Use Room Type and change the Room Name to the label you want to use.

    • On the Structure panel, uncheck the Roof Over This Room and Ceiling Over This Room options and click OK.

  7. Select each wall and use the Open Object edit button to open the Wall Specification dialog.

  8. In this dialog you can change the Wall Type, to a wall type better suited for a window well. In this example, 8" Concrete Stem Wall is used.

    Note: If you are using Home Designer Pro, you can find the Wall Type selection menu under the Wall Types panel of the Wall Specification dialog.

  9. Click OK to accept this change.

    To create the curved wall shown in this example, select the front wall of the window well and click the Change Line/Arc edit button to convert the front wall into a curved wall.

  10. Move back up to Floor 1 and select Tools> Reference Floors> Reference Floor Display .

  11. If you do not already have a terrain perimeter, select Terrain> Create Terrain Perimeter to create one.

  12. Select Terrain> Feature> Terrain Hole and draw a hole over the window well as shown below.

    If you created a curved front wall, select the front edge of the terrain hole, and click the Change Line/Arc edit button to convert it into a curved hole to match the window well below.

  13. Open a Camera view to see the resulting window well.
