You could create as many SH3D documents as the number of steps, but I guess it's not what you want. If the home you have to design doesn't have levels, you could use the level feature of Sweet Home 3D to show the different steps, using levels at the same elevation (or almost the same elevation according to what you want to show). See the file attached to this message.
