Landlord asked us to vacate the house to convert 2bhk to 3bhk

Hi, My landlord is an NRI who owns a 3bhk house. One of the rooms was locked with some of their stuff kept in it. Now, they have vacated the extra room and want to rent out as 3bhk at the end of 11 months of stay. At the time of renting the house, both parties had agreed that the renting will be for long term (more than 2 years). Hence, we had also decided on the increase of rent at end of 11 months which is mentioned in the rent agreement. However, long term renting is not mentioned in rent agreement. Now, they want to deduct 1 month rent towards repainting and cleaning charges. This has been agreed upon in the rental agreement as well. Questions are: 1. Is changing from 2bhk to 3bhk a change of basic premise of the rental agreement? 2. Does this void any other clauses agreed upon in the agreement like deduction of 1 month rent for repainting charges? Rental agreement was signed for 11 months and 11 months have been completed, and expectation was that a new agreement will be signed with increase of rent by a pre-agreed amount.
