Public-Facing – Extra security measures might be more of a concern if you’re placing your building in an area that is more public-facing than a garden. Features such as security windows or even having no windows at all, and the ability to lock all opening doors are usually much more important when you have something that is more public-facing. We found at least 3 sheds that have options that you might find a better fit if this is a concern you have.

More Child Friendly – If you have children and you are looking for something that has that little extra in terms of durability then tougher glazing options might be a better option. Here we have at least 3 other options that will fill those needs.
