Residential layout plan and road

If the construction is not as per approved layout/plan then that is violation and the construction not approved can be dismantled or there will be heavy fine .

Yes. Agreed with the above experts.

Did you challange the ground fact with UDA i.e., competent authority ?

Please mewntion what is this road? National highway, state highway, link road to national highway or approach road  etc. 

This is not allowd, the road from your nrighbor needs to meet your land or else they are breaching appendix 2A point 3 of town planning act. When the layout is finished there will be relinquishment deed done for all roads in the layout in favour of UDA, once done,  you can connect your neighbor road yourself to your land.
