The interior of Sky High Castle includes hand-hewn beams overhead, two cast-bronze ceiling fans that feature retractable fan-blades, two floors each having a large stone fireplace, and many windows taking advantage of the surrounding views.

Outside, the property is also special. The Castle is perched atop a hill and large chert, stone cliffs overlooking a river valley where Shoal Creek flows. The striking appearance comes from the fact that the Castle and cliffs are made of the same color of stone, so that the whole is of impressive height and width. It is 180 feet of elevation change down to Shoal Creek below.

The hillsides have been terraced with many rock walls at various levels. Walkways and stairs lead around the property offering many splendid views of the valley and Castle. Rose moss, phlox, carnations and columbine make a home on the rock walls and terraces. Surrounding the Castle are oak woods and a city park along Shoal Creek comes up to the property line on one hillside.
