Really nothing too special, the original model has a house part and a base part, the base part has a little wall that makes the ‘door’ a bit smaller. If you try to scale the model to make it a bit larger than you might want to have the little wall from the original removed. This is a file for that that I thought I'd upload so if I need it again Id be able to find it.
You will still need the top part from the original other parts from @MrMegaTronic_99635
The author remixed this model.
