In Old Testament times, the “house of God” was a building in one specific location (Psa 84:10). However, after Jesus died on the cross, the physical body of the Christian is the temple (or house) of God. Again, the house of God is not a church building now. Christians are the house of God, but only if they hold on to their courage and the hope of which they boast (Heb 3:6). See also 1 Cor 3:16,17 in the NKJV.
Please also know that the man made, so-called tabernacle inside the Catholic church where the left over wafers (or Eucharist) are kept is not the house of God:
However, the Most High does not live in houses made by men. (Acts 7:48)
