It is very good that the Deity is facing East. Yes, the room above the Deity should be kept vacant. Yes, you can store Ratha Yatra festival gear or books there, also. The proposed pinnacle should not have Om, but shastic or cakra, Krsna's weapon. So everything is nice, and I shall be glad to come for the Deity installation and temple opening in January.
