On PC we can Shift+Delete, I don’t know if you have an equivalent on consoles.
Otherwise, with admin commands:
“BuildingIdentify” then “BuildingDestroy” comes to mind, but if you placed that thing on foundations the foundations will be destroyed together with it, all of them.
If you placed this in your base, this method deletes the entire base 
If you placed the Focus Altar in an isolated area, then there is hope
