Floor wise car parking in a 'Block' type community

Hello Thanks for reading my query in advance & would appreciate a response. We stay in a community in New Delhi where there are multiple blocks such as A, B, C etc each having around 10-15 houses. I stay in Block 'B' where I've one car and there are around 10 to 12 houeses. I stay on First floor and my uncle stays on ground floor (who has two cars). We have a common house where first floor is fully owned by him and first and second floors are owned by me. The issue is with my car parking that I've to park my car always far from my house (wherever I get space) as my uncle insists that both his cars are parked just outside the house (where there is parking space). I need to fix this matter now in an amicable manner, so need an advise from you. According to me, the space before our house till the road should be 'shared' (this is leaving the common road used by the public there). With the current scenario, ttally, only two cars can be kept (back to back) adjacent to our house; so I suggest that my Uncle parks one car and I park mine. I'm also in a process of buying another car, which of course I will be parking somewhere else, so I believe he should also be parking his second car elsewhere. Ideally, this would have a win-win situation. Earlier, as well I've spoken with him however, it hasn't materialized. What do you suggest I do in this case? Please advise the soonest.
