I would like to design a deck to go around our above-ground pool. What is the best way to do this?


You can easily drop a pool or spa into a deck by specifying part of the deck room as "Open Below" in the Room Specification dialog.


To drop a pool into a deck platform

  1. From the menu, select View> Library Browser  from the menu, then select an above ground pool or spa to place in your plan. 

    In Home Designer 2014 and earlier versions, select Library> Library Browser.

    For the purposes of this example, browse to Exteriors> Recreation> Pools, Spas & Waterfront> Hot Tubs

  2. Move your cursor into the drawing area and click to place the hot tub.

  3. Using the Select Objects  tool, click on the pool to select it then click the Open Object  edit button to display the Fixture Specification dialog:


    Specify the size of the actual pool or hot tub used in your project.

  4. Position the hot tub or pool where you want it in your plan.

  5. Select Build> Decks> Straight Deck Edge  from the menu, then click and drag to draw a second Deck room entirely inside the first one.

    • If your spa has rounded edges, such as in our example, you can create the shape and then use the Change Line/Arc edit tool on a straight corner segment and adjust the arc to match that of the spa.

    • If your pool is circular or has a round edge, you may also want to use the Curved Deck Edge  tool.

  6. Using the edit handles, position the deck edges so that they align with the outside edges of the pool symbol.

    • In Home Designer 2012 and newer versions, when the deck edges are correctly positioned, an invisible wall will automatically connect this island room area to the exterior railing of the deck.

    • In Home Designer version 10 and earlier, you will need to create your own Straight Deck Edge connecting the room.  (This step is very important. If you do not connect the deck edges to the outer railing, the deck platform will continue through the open area.)

  7. Using the Select Objects  tool, click in the new Deck room to select it and click the Open Object  edit button.

    It is likely on your first click that you will select the pool instead of the room.  Click the Select Next Object edit button or press the Tab key on your keyboard until the room is selected.

  8. In the Room Specification dialog:

    • On the General panel of the Room Specification dialog, select Open Below from the Room Type drop-down list.

    • On the Structure panel, uncheck Roof Over This Room.

    • Click OK to close the dialog and apply your changes.

  9. Select 3D> Create Camera View> Full Overview  from the menu to see the results.

  10. If needed, open up the Pool or Spa's Specification dialog, and lower its Floor to Bottom value so that it rests inside of the deck area and click OK.
