You would have to add another meaning to the word apostle(sent one) in order to make that work out. All believers are commanded to go out as part of the great commission.
I'm speaking of the foundation .. not the church itself. Eleven of the twelve suffered a martyrs death. John was exiled. The foundation isn't still being built. It is built.
Ephesians 2:19-22
19 Consequently, you are no longer foreigners and strangers, but fellow citizens with God’s people and also members of His household, 20 built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone.21 In him the whole building is joined together and rises to become a holy temple in the Lord. 22 And in Him you too are being built together to become a dwelling in which God lives by his Spirit.
