Let objects spawn by pressing a button

Hello there,
I want to make a “Wall” where you can click to select which room-type you want to expand with.
Could you help me with spawning the room by Pressing F for example?

put your building part in a blueprint class. Hook a spawn actor of Class node up to Input event for the F key.
Set the location of the spawn to where you want it to be.
To answer any more specifically I think I will need more specific questions.
