So far we haven't hung anything up in the wardrobe and tend to pile things on top of each other - boots in a bag, bag of towels, small rucksack etc. We are thinking it would be better to shelve the wardrobe but worried about damaging the outside by going through the walls with the screws. Has anyone else done this and have any tips? On one side of the wardrobe is the doorway to the outside and on the other is the shower room.
