Gap of 3 saffs between two saffs

Q: If in congregational prayers and Jumu'ah and Eidain, the Imam is in the indoor hall of the masjid and saffs are made behind him and the door of the hall is closed but not locked and saffs are also made outside, but there is a distance of 3 saffs between the last indoor saff and the first outdoor saff, are the congregational prayers or Jumu'ah or Eidain prayers valid?
