Performing Tawaf far away from the Ka'bah
What is the ruling of performing Tawaf behind the standing place (of Ibrahim) or behind (the well of) Zamzam?
There is no harm in that, even if the person performed the Tawaf in the areas with awnings in the Masjid that is sufficient for him, However, the closer he is to the Ka'bah, the better. If there is room there and there is no crowding, he should come near to the Ka'bah and that is better. If that is difficult for him, he should perform Tawaf at a distance, and there is no problem with that.
