What does the farmhouse in animal farm symbolize

I read Animal farm, (or part of it) recently, not for school though, i read it because-- of reasons that do not answer this question. Anyway, in the beginning of the book the farm house represents a Soviet Union society, during the communists rule. The book begins after a revolution, and it soon develops its own form of Government and structure. I did not get past this part, but I think it should be enough to go on. I hope this helps, please mark brainliest if it did, thank you very much :)
