My GH is mounted on paving. Inside it's paved on one side, with a gravel path down the centre and a bed to the other side. There's ample room at the top and near the door to have plants growing in buckets either side of the bed on the paving.
The paved side means I can have a potting bench the length of the GH, which stands on a hard surface and can store pots underneath. At the height of the growing season the bench houses pots of low growing veg like chillies, peppers and aubergines.
I grow direct in the bed and the soil does need to be changed although I also grow in bottomless pots so just change the top few inches. Never had a problem with pests getting into the GH through the bed but as blairs pointed out GH does get damp over winter, hadn't realised it was the soil causing the damp and this could be a problem if your GH is made from wood.
