Builder's Houses are enormously important. Each player should have 2 Builder's Houses after completing the introductory tutorial. For each Builder's House, one construction job is allowed to build in parallel; a player with 4 Builder's Houses can build/upgrade 4 things at once. A minimum of 4 is often suggested, but 5 are never too many.
