Meeting with the builder No.2

After asking "E" to redraw the plans to accomodate a double carport so that we will get back the area we lost, we were contacted by the head office for a meeting.
The meeting was some what a repeat of the first meeting.
We said well we should have been informed of the change at the time and asked if that was ok. the argument was that it was ONLY 30-40cm's but nevertheless they should have checked with us.
So at the meeting we were informed that
1) If we want the double carport, we will need permission from the council to build over the easement - and from the relevant authorities - (which we knew)
2) We would need to apply for dispensation from the neighbours (permission) - from all three of the neighbours because we were building over an easement (which we were surprised with & was going to cost us extra)
3) We had to build it 1m away from the boundary because we were building over and easement.
4) After all this trouble if the council said "no" we would have to go back and redraw the plans which was going to cost us..
So we went away from that meeting not deciding and telling them that we would get back to them.
I must clarify when we said double carport our impression was the same as a garage but with no wall at the rear of the structure.
