In the Sims 2 PC can you make more than 5 floors?

Yes you can just copy and paste "setHigestAllowedLevel (the level you want)" into the cheat bar by holding down on the keys Ctrl, Shift and C. Make sure you are not on a lot or if you are you can enter the cheat but you then have to leave the lot and then re enter it... By the way, in some cases you may have to add the 5th floor walls first then add just one pillar then the 6th floor platform should show up! You can then delete the pillar and carry on building or you can keep the pillar, your choice!

Happy building... or simming :/
