What are the Rules and Regulation to consider before plotting in LAND in India?

Q: Let us assume, I have a Land of 14000 Square in city. It was an agricultural land and I got it converted to construable land under Section 143 of Uttar Pradesh.

I have already started construction of school in 11000 Square yards of land(Got the school map also approved by the local authority ).

Now, I am willing to do plotting in remaining 3000 Square yard of land. I was planning to create plots 100 square yard each and will also construct a road for access for each plot.

What is my concern
Do I need to consider the size of road, It their any law regarding this. Because I will construct road as per the practical requirement.
Road as wide as 20 feet is enough as per my experience.
But the architect who was building the layout is troubling me, he is saying whenever someone do plotting in colony they need 30 feet wide road.

My argument is I am not constructing a colony or not even starting a great real estate project. I am trying to sell my land in form of plot, which is already converted to construable land.

My age is only 25 Years and I am doing this project in small town where most people dont have exact knowledge of law.
It is my social initiative to build a school and money I will get after selling with be utilized for the development of school.
We have very very less fees in our CBSE Pattern English medium school. It is only 250 INR per month. We are building another branch in 11000 square yard land(Mentioned above).
I am just trying to fulfill my father dream of educating less privileged people around me.
