Sharing perpetual lease land between friends and joint construction

Gurus, Me and my friend want to purchase a plot (perpetual lease plot in township) in residential zone of 7000 sqft jointly in PCMC (Pune, Maharashtra) area. We are planning to divide the ownership and plot in equal size. After buying we want to build the property jointly by availing the loan from bank. Questions - is it possible to divide land before construction or after construction? also we want to make an agreement with below conditions - 1. Both parties will avail the plan & permission to develop the building for availing the bank loan**. **Bank loan is subject to approval, I will check with the bank. 2. Both parties will be sharing the land to construct the property, the construction would be individual. (2 bunglow) 3. Property will be construct as per the T&P guidance, any alteration/extension can be carried out only after agreement of both parties. 4. In case of selling the property (with bunglow), the new owner(buyer) can avail the ownership of land and the construction. Can we make such conditional agreement.
