An outdoor playhouse kit is for a little kid. This means you'd want to keep an extra eye out on the child while it is playing. With that being said, you'd want a playhouse that has a sizeable window.
The ideal playhouse for toddlers is one that has large and wide windows. The windows must be low enough so you can easily get a glimpse as to what your child is doing. An open model that has doors and windows may be suitable for your kid as well.
