My rear garden effectively mounts to a very steep slope. Over the last year or two I've successfully fenced off the entire garden (up a hill and
then several straight fences) but I'm stuck with the last bit;
The slope is very steep, probably over 45 degrees - but the fence needs to run across the length of the slope from one side to another rather than
up/down it.
The posts will be timber and the fencing itself either featherboard/pailing which I will do myself, my quandry is how to mount the posts sufficiently
so that they are secure.
The fence height above ground will be approximately 2.5m (so fairly high) and the area gets a bit of stick from wind etc. I was initially intending to
dig down c.1m and use postcrete to mount the metal 'stake' type posts (that way I get the benefit of both the stake and the postcrete).
...unfortunately due to 'aesthetic requirements' given by the wife, the concrete/fixings shouldn't be visible so it's not like I
could build a mounting base for each post.
There will only be 3 posts.
I welcome ideas... I've googled but everything about fence building on slopes is about going up/down them.
Full concrete posts, but secure the fence to the inside face of the posts so they cant be seen.
But how do I secure the concrete posts into the ground, and concrete posts would need even more foundations than timber ones.
get really long posts (or long metal bits on the bottom of the posts) and burry the whole foundation underground ?
Side way view, if I understand your problem correctly.
Either bury something in the ground - concrete post, metal etc and bolt a post to it (as shown in blue) or have a supports, (as in red), assuming the
supports cannot go on the other side to be out of view, they could be made in to a feature.
Although I have erected one fence, not on a slope, I am not a fencer so have no idea of either of these will work for you!

Your photo shows the problem I have but unfortunately I don't know whether either solution would work.
The red idea would be my preference but would intrude into the garden itself. The blue idea I would struggle with due to the gradient of the balcony
itself.
I'll get a few photos tonight. Thanks for taking the time to reply though, any ideas are a help 
You dont need more/larger foundations, just ones that start deeper, and longer posts.

Will result with a little more dig out, but thats the nature of the slope!
What's the other side of the fence - can you have the support struts on the far side?
When you say only 3 posts - does that include the corners? i.e. Is the fence 2 panels or 4?

I would expect you will need some sort of bracing on a fence that tall and subject to wind loads, can you turn the bracing into something attractive
like a bench seat?

Could you do the Anchors at an angle, say 135° and bury them Perpendicular to Slope,
Canīt attach pic, but will be glad to e-mail Paint Cad Drawing...
Anchors made of Rebar and Concrete with Brackets made of steel.
Bolts to affix Posts to Brackets.
HTH.
