Fixing a 100x100 post to floor

[MuffDaddy]

This weekend I will embark on shed move/build project. On moving the summerhouse I will be left with a base, set on railway sleepers. In building the new storage shed/wood store I want to place 4 100x100 posts on to the floor to create an open frame. What would be the neatest way to do this? I'd really like something hidden rather than fence post supports.

I wasn't clear.

The base is already there, as is the floor of the future shed. So there is no "dig a hole" option. What I need is a way of placing the uprights directly onto the floor and securing them.

Even better, a little over engineering never hurt.
