The early church met both ‘from house to house’ as well as ‘together in the temple’.

Day after day, in the temple courts and from house to house, they never stopped teaching and proclaiming the good news that Jesus is the Christ. Acts 5:42
 
Greet Priscilla and Aquila, my fellow workers in Christ Jesus. Greet also the church that meets at their house. Romans 16:3,5
