Help! Ciudad Enamorada Library with underground nightclub

hi all! I know that so many of you love to create, design and use the sims build mode for your imagination. unfortunately, I am not one of these people. I love my buildings to function and be detailed for my storytelling but I'm not as skilled with the buikding tool. I was wondering, if someone here would like to take on a challenge- I wanted for a long time to edit the Library in Ciudad Enamorada- to be a boring, regular library on the two first floors, with a secret, lavish pink nightblub underneath, with bar, danc efloor, and some private rooms... would anybody be interested to develope this idea?
