Lift the cottage. Some thoughts.

[bakterie]

The long-postponed cabin lift is now in the planning stage. Hopefully, it will happen later this year or next.

Here's how it looks now:


To make future lifts easier, I thought of reducing the number of points resting on the ground by putting steel beams underneath. This is what I was thinking:



I thought the beams would rest on the numbered points.

So what profile should I use? H? I?
What dimension?
Is the span for the middle beam too long?

Is it impossible to detach the deck and put it back?

No, it is not impossible to loosen it. However, I don't think it is necessary.

I have reconsidered, and will place a total of four beams under the cabin, rotated 90 degrees compared to my illustrations in the first post. Three under the cabin, and one at the front of the porch (maybe I should call it a veranda, it has a roof).

After examining the existing dimensions more closely, it turns out that the existing wooden beams have an approximate dimension of 100x100. If I now use pressure-treated wood with dimensions of 125x125, it should reasonably suffice.

As it seems now, the main difficulty will be getting the new beams under the cabin. It is cramped between buildings and the terrain.

Now the cabin is lifted. I ended up using 95x95, simply because that was what I could get hold of at short notice. It worked excellently. Attaching a picture of the cabin being lifted.
