The Choir difference step up!
Well here is what i would do its not what you will be thinking of but this is my idea:
If you have Pets Expansion this is a must for this option!
First go into build mode and go under Those things that make buildings higher
If dont have pets then this is wont work but if u dont here is a brick and a wooden one you can use i will say make a how big part u need for your choir thing and then if u have pets theres another one of these things this one u can put on top of the lower..what ever its called thing...you can add flooring and wallpaper...i have tried this
it works myself
I dont think this is wat kinda thing your talking about but yeah thats my way!
