[fatum]

I've been searching around quite a bit, but I haven't found much helpful information on the subject. Could anyone provide tips for remembering the appropriate time from using each particle? Would this be correct usage for で?

僕の家で

Intended translation being "In my house"

I'm not sure if 僕 is the correct word to use in the situation either, but I think the original idea can be understood!

Thanks for any help.
