Have to agree with rdmir. Wood is a better proposition. Better sound insulation- Better ventilation- looks better.
One of my neighbours had a metal shed- The sound of Seagulls landing on it was like someone bashing a dustbin. Windy weather caused a problem on opening the doors after a couple of years and direct sunlight used the get it too hot to touch- even in the UK.
