How do I create a staircase with an opening to the floor above?


Home Designer makes placing stair cases fast and easy. To make it easier to see our stairs lets tile our plan with a 3d view.


To tile the plan view and a 3d view

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

  2. Set up a 3D view so that you can see your progress. Create an interior room similar to the one shown in the image below. 

  3. Next, select 3D> Create Camera View> Full Camera  to create a Full Camera view looking at the corner of this room where you will create our staircase as illustrated in the image below. 


  4. Select Window> Tile Vertically  so that you can place the 3D view side-by-side with the plan view.


Now you are ready to begin the first step, creating the staircase.


To create a staircase

  1. With the 2D Floor Plan view active, select Build> Stairs> Straight Stairs  and to draw a staircase, you simply left click, drag and release the mouse button to create the stairs.

    In this example, create the staircase on the first floor that will reach the second floor and intentionally drawn this staircase too short, which allows you to modify the staircase so that it reaches the second floor.

  2. In the floor plan view, activate the Select Objects  tool, select the staircase, and click on the Open Object  edit tool to display the Staircase Specification dialog.


    Notice that Home Designer has detected the short staircase, and gives us a message to let us know.

  3. Home Designer also gives us a way to automatically extend the staircase to reach the second floor. Let's click the Make Best Fit button, and then select OK.

    In Home Designer version 9.0 and prior programs, this button was called Make Reach.

  4. You can now see that your staircase reaches the second floor as illustrated below.


Now that you've created the staircase, open it again for specification so that you can configure the structure of the staircase.


To adjust staircase structure

  1. In the floor plan view, activate the Select Objects  tool, select the staircase, and click on the Open Object  edit tool to display the Staircase Specification dialog.

  2. For the purposes of this example, you want to have fourteen treads instead of sixteen, so change the # Treads value to 14 by moving the radio button to Lock Number of Treads* so that you can modify this field.

    *Ability to lock number of treads was only available in the Home Designer Pro  for version 9.0 and prior programs.

    Notice that Home Designer has updated the Length, the Section Width, and also gives us a message at the top saying that the staircase is a steep staircase.

  3. If you change the number of treads to seventeen, you can see that Home Designer has detected this, and has let you know that the staircase is a shallow staircase.

    Home Designer also provides a recommended ­­tread depth here, and can calculate all of the settings for your staircase automatically. In addition, using the Lock value feature, you can customize your staircase to your exact specifications.

To move the staircase

  1. Use the Select Objects  tool to select the staircase, and note the edit handles that display. 

  2. Select the middle move handle, and move it up against the far wall.

  3. In the 3D view, see that the railing has been attached to the wall and a ­stringer that has been created along the steps.

Now that you have the staircase configured the way you would like it, move to the next step, creating an opening above the staircase.


To create a stairwell

  1. In the 3D view see that the staircase is blocked by the ceiling.

  2. To solve this, in Plan View, select the staircase, and click on the Auto Stairwell  edit button.

  3. Now in the 3D view, see that a hole has been cut out of the ceiling.

  4. Close the existing 3D view, go to the second floor, and create another 3D view.

    From here you can see that the stairwell opening has a railing around it, and there is an opening at the top of the stairs between the wall in the railing.

When you return to plan view you can see that Home Designer has created these railings as standard architectural objects on Floor 2.

For example, you could select each of the railings, and you could edit them just like any other railing in Home Designer.

A new room in the center of the railings was also created. This room is marked as a stairwell, which means that it has no floor and is open below.
