Well, Sanctuary house of prayer is in building #3 (4 if you include the WCV years). We are in what you would call the Wilderness or Moses years of our house of prayer. The tabernacle was essentially portable (poles/tents) and the Israelite could camp around the tabernacle wherever they needed to while in the wilderness. However in this new building I am getting more of a David feeling, where David had it in his heart to have a permanent home but did not finish the job until his son, Soloman finished the foundation.
The building we are in now fits many of our needs and it feels great in there; but we are still waiting on the permanent home. I look forward to the day when the Lord gets us into a permanent home and we will have the feeling the Israelites had when the foundation was laid and they sang, "The Lord is good and his mercy endures forever"
