QUESTION

How do I create a small room under a staircase? 

A small closet under a staircase


ANSWER

Many plans use the space beneath staircases for storage or utility closets. When walls are drawn under a staircase in Chief Architect, the walls will be cut off automatically by the stairs making it easy to create a room in this area.


To create a room under a staircase

  1. Draw your staircase to your specifications using the Stair  tools.  

    In this example, an L-shaped staircase is created.

    Note: For more information on creating the different types of staircases available in Chief Architect, see video #71:Stair Basics.

  2. Select Build> Wall> Straight Interior Wall Straight Interior Wall icon from the menu.


  3. Draw the interior walls beneath the stair so that the surface of the walls align with the outer edge of the staircase.

    In this example, the newly drawn walls are green in the image below.

    Drawing the interior walls

    Note: The direction the wall is drawn will dictate how the wall is generated; if you draw the wall snapping to the edge of the Stairs, but the wall generates outside of the stairs rather than underneath it, reverse the direction you are drawing and the walls will generate underneath, rather than outside.

    Be sure not to draw the end of your room past the second tread at the bottom of the staircase.

  4. Using the Select Objects Select Objects icon tool, select the staircase and click the Open Object Open Object icon edit button.


  5. On the Style panel of the Staircase Specification dialog that opens, uncheck the box next to Open Risers, check the box next to Open Underneath, then click OK.

    You can also set the Pattern Type to "No Pattern" on the Fill Style panel if you want to be able to see under the staircase in floor plan view.


  6. Select Build> Door> Hinged Door Hinged Door icon from the menu, and click on one of the interior walls you just drew to place a door to your room.
