Creating sa spell

[charlesmcl71]

I am hoping someone can help me. I am new to modding and I love playing skyrim and wanted to add a couple thing to my house. Now I live in Springwood Estate in Solitude and I am using Hall of the Dovaquiin for an armor and weapon display. To add it to your house you are given a spell that adds a hatch in your basement floor. How is this achieved? Does anyone know?
