Enroachment of residential plot on road in front

Hello I need advice n solution for particular situation arise ,when my construction of house has began. According to situation details are 1. We had purchased plot admesuring 1230 sq ft from second party in may 2018. We got registered as third party . As per rules in Hyderabad we had paid all taxes and started the construction . 2.Actually first party owns land of 1000 sqyrd plot ,which has been diveded to 5 plots plus one private road taken from that land itself. 3.so now we had enroached for one feet from our rcc structure of ground level . That is not from ground , but from balcony we are enroaching one feet . 4 . My neighbour who is totally outside plot from our 1000 sq yrd is objecting and harassing us he will stop construction if doesnot stop that enroachment. 5. Actually our 1000 sq yrd is separate land which is connected to cooperative society, as per society lay out my neighbour house is constructed . 6. But our 1000 sq yrd lay out has been done separately which does not come under that society. Now the point is as per our registration details we are 3.5 feet outward to our neighbours plot which is also mentioned in registration. 7. So my neighbour house will go further more one feet inward which is negligible, but he is creating unnecessary issues . 8 . I need solution to handle this person . Thanks in advance .
