Ok thanks for all the responses - good points on pivots perhaps not being ideal! As a bit of background - this is effectively as a replacement for a normal window and there is a patio door 2m away so may not be the main entrance / exit - but my thinking is that it would be nice to be able to open the dining room up to the patio so I was looking at a big window that can open (and liked the idea of bench seating either side). Pivot was just because it looks good but isn't an absolute requirement!
Other large windows would work too - how many of the issues would be solved if I went for a normal hinged window (would still like it to be big though)?
