Full height windows

[sainty]

I've been asked to make some full height windows/door for a studio in someones back garden. (It's basically a pitched roof on a dwarf wall over a converted swimming pool)

They are having a slate floor put down that will run from the end of the pool inside out into a patio area outside. They want the windows to sit directly on top of the slate. I told them that I wasnt comfortable sitting the cill directly on the slate and would prefer to raise it from the ground. Am I worrying unnecessarily? What measures can I take to improve the longevity of the windows? Obviously I can bed it on some sort of DPC but that doesn't seem enough to me (what to bed it on?)

Bed it on slate ;D Thats what they used to use for DPC .

You will need to make sure that water does not pond on the patio, otherwise the cill could be sitting in water.

Id be tempted to bed it on a single brick and have a slate upstand hiding the brick .

I am told that the slate will be laid with a fall away from the building - but I'm still not filled with confidence.

Oh, thanks JFC

Oh, thanks JFC for the second post that was too quick for me!

i've just fitted a set, and stated that a single bed of brick be put down first.

frankly i would have thought that the movement of the wooden frame would cause too many problems with the slate being as rigid as it is ( and hence fragile)

jason's idea is much better.
