For what my advice is worth.
1) The more that you dismantle, the more likely you are to have problems realigning on reassembly.
So if possible, only dismantle to the point where the parts will pass through the house.
If you can lever the machine up onto rollers / trolley and wheel through, complete, do so.
I bitterly regret having separated the column and base when I first moved my Mill / Drill. If I had had had the folding crane then, I would have used it. It was much easier using the crane, when moving into this shop. Just worked through the doorway to lift the machine on to the bench, and bolt it down. Levered bench onto small rollers, and then put a sturdy piece of timber across door way. Used a scissor jack and timber to "jack and pack" bench and machine into position. Slow but safer than manual lifting and pushing.
2) You should be able to hire a folding Engine Crane.
This would allow you to lift the heavy parts onto a trolley (or two) to wheel through the house. The crane can then be folded, wheeled through, unfolded and used to lift the reassembled machine onto the stand / bench, as above.
It may be slow, but jacking and packing will allow you to lift heavy weights to a height suitable for most workshop purposes. BUT DO make sure that the weight is not going to fall onto you, or anything else.
A lot of heavy weights used to lifted and moved, down mines, by jacking and packing. It just needs patience and plenty of packing. Beware of bricks: they will crumble! Paving slabs need to be supported completely, not just at the edges.
