We have the capability to compensate for slopes in your yard without excavation. This ability is limited to certain models of our larger angle based structures. In short, we will use different lengths of ladder legs and swing legs to maintain a level play deck and swing beam. This capability is limited to slopes up to 24" over the width of the structure. Any slope greater than that will require excavation. There is an additional charge for this adaptation, which will be determined by how much slope we are working with. Ask your sales consultant about the details.
