Dispute between brothers because of one common entry gate

Sir, i have a joint family. My elder brother has built a new home for his family and now lives there only. In this home I live with my family and on the top floor my father and divorced sister. Elder brother comes to this home almost everyday as he has made his portion a godown for his business. The problem is that on every Sundays he use to get up early in the morning and then come to this home to take his business material at 5-6am. It is very difficult for us to get up in the cold morning to open the gate and moreover if we had slept late. Now for this reason i asked him that he may keep his material which he takes on every Sunday in his new house and all the rest material can be kept here only. On this topic he started saying to make your way separate and add a now door for yourself. He even called the police for this matter. And the police officer said that sir your portion is of the ground floor you made your separate door and clear his way. I want to ask that was the decision made by the police man was right? What should I do now?
