Garden Office on a steep slope

[Lesgrandepotato]

Looking at building a Garden office from one of these frames http://www.ebay.co.uk/itm/Glamping-Pod-New-Oval-De...

Best place would be to the right of a ruined mill in our garden - the ground is sloped here to a reasonable degree - perhaps 20degrees maximum. I'm thinking we'll need 4 our more solid pad stones to take a set of legs (for the full alien landing craft look).

The challenge is how to avoid it migrating down hill? dig out a decent area and hammer in metal rebar as a basic pile for say 1m? and then a shuttered box? What does the collective wisdom think? suspect it'll be about a tonne all up as its built.

The ground is stony and solid with plenty of dropped stone

I've used these concrete posts before on sloping ground, with framework to create a base.

I built a deck on a 40 degree slope, 3m tall at the furthest point out.
I'm building a lower deck area with a shed/office and I'm using similar principles.

For the upper area I used 6x6 posts and 2x10 bearer joists with 6x2 joists.
If I was doing a garden office on a slope I'd use a similar arrangement, the last thing you want happening is frost heave on the posts and the whole thing disappearing down the slope on you!

Here's what I built http://www.pistonheads.com/gassing/topic.asp?t=159...
The lower deck area I'm building will have a shed on it. I'm using 4x4s for that, I'm not using bearer joists though this time as I don't have the height and shouldn't really need it.
