You can check the Custom ViewportLayout source code sample.

Here is the code extracted from the above sample

private static void InitializeViewportsByLayoutType(Design design, viewportLayoutType layout)
{
    int viewportsNumber;
    switch (layout)
    {
        case viewportLayoutType.SingleViewport:
            viewportsNumber = 1;
            break;
        case viewportLayoutType.TwoViewportsVertical:
        case viewportLayoutType.TwoViewportsHorizontal:
            viewportsNumber = 2;
            break;
        case viewportLayoutType.ThreeViewportsWithOneOnBottom:
        case viewportLayoutType.ThreeViewportsWithOneOnLeft:
        case viewportLayoutType.ThreeViewportsWithOneOnRight:
        case viewportLayoutType.ThreeViewportsWithOneOnTop:
            viewportsNumber = 3;
            break;
        case viewportLayoutType.FourViewports:
        case viewportLayoutType.Stacked:
            viewportsNumber = 4;
            break;
        default:
            viewportsNumber = 1;
            break;
    }

    if (design.Viewports.Count > viewportsNumber)
    {
        while (design.Viewports.Count > viewportsNumber)
            design.Viewports.RemoveAt(design.Viewports.Count - 1);
    }
    else
    {
        while (design.Viewports.Count < viewportsNumber)
        {
            design.Viewports.Add((Viewport)design.Viewports[0].Clone());
        }
    }

    // When changing the LayoutMode, the UpdateViewportsSizeAndLocation() method is called as well.
    design.LayoutMode = layout;
}
