We have some land that needs to be raised some. The situation is like this:



So the land is not any lower than other land around it, but it's considerably lower than a road and small irrigation canal alongside it. It's about 1.5 meters below that.

While we probably won't raise the entire land area to the same level as the road, we should probably raise the area where the house is going to be by at least 1.50m and probably by 2m. (Does anyone know the typical cost to raise about 1 ngan or so by 2 meters?)

Of course the land needs time to settle, probably at least a year.

So I was thinking, would the following be possible: Put in the house footings at the current level and make the posts higher by 1.5-2 meters, then fill up the land afterwards so the footings are in solid soil, and go on from there? So like this:



As opposed to this:



Would the former be a lot more expensive, and is it worthwhile to do? Is the added cost just the extra length for the concrete poles?
