About 3 metres is the maximum although most suppliers (Pilkington, St Gobain) prefer around 2.4 metres. It's largely dependent on the edge fixing system you use; whether continuous mullions and rails or point fixings like Pilkingtons Planar system. You have also to remember that such glass needs to be toughened or, at the very least, laminated and the ratio of length of the shortest to the longest side should not exceed 1:7.
Also, glass is heavy and any support system will need to be robust enough to support the sheer weight of the glass together with the imposed wind loads. This can sometimes lead lead to cumbersome structure. Check out recent work by Fosters, Piano or Calatrava for elegant and minimal steelwork.
There is more, but if you're merely at the stage of planning out your elevation that should do. Hope it all works out on paper the way it's in your head right now.
