To raise a house off its existing support system they install steel beams that extend beyond the exterior and use neumatic jacks with a central control panel that can be used to control each jack. Once everything is in place, which is time for setting up, the house goes up pretty quickly. They build wood platforms to support the house from the underside and stop periodically to add wood members to it. Pretty interesting to watch. The process is done in reverse once the excavation and foundation has been completed.

A bob cat or similar equipment is used to remove the earth under the cottage and dig the footings.

If your cottage already has a 6' height in front I would guess that you would go for a 2'-3' raise on the front which equates to only a small raise off the ground in the rear. It all sounds quite simple but you need experienced people to do it. There are quite a few in NH that are qualified to do so. The ones I know of do this type of work on the small lakes further south in NH.
