Hi Marsha, you might want to ask a traditional priest about erecting them anywhere at home. I know the NO people think they can erect anything they want where ever they want but that just isn't very reverent.
A beautiful, meditation garden would be lovely; a couple of outdoor statues with flowers planted would be very calming and serene. This is what convent gardens are like. A wonderful place to meditate, pray the rosary etc and when tending the gardens I think you would feel like you're not alone
