Our small roof is notched to fit between the posts, and doesn't require our roof pegs. So it is a great option for younger children who are still working on their fine motor skills. It folds flat for easy storage, and will work with any of our kits. The small roof comes in 2 options: our solid alder wood roof or our colored panel roof that is can be used with any of our MODplayhouse kits. Measures approximately 5" x 8.5".
