yes it is possible.
easy work flow as Lumion has layers that you can turn on and off - old house on one layer - new house on a different layer.
Set them both up inside one Lumion scene. Turn the old house off - turn the new house on - vice versa.
.....and that is just one way (although complexities could vary wildly).
of course this all depends on the "weight" of the models, the amount of texturing, memory on the graphics card, memory on the computer, etc, etc........

what software are you using to build the models of the houses in?
