Mall usually refers to shopping malls, especially when refering to buildings. Wikipedia says "A shopping mall, shopping center/centre, shopping arcade, shopping precinct, or simply mall is one or more buildings forming a complex of shops representing merchandisers, with interconnecting walkways enabling visitors to walk from unit to unit, along with a parking area – a modern, indoor version of the traditional marketplaces."
That implies more than simply receiving things, it implies that you pay for them, and I would say it implies that what you pay with isn't ration stamps or something like that, but more like some currency. So malls could exist in systems with currency, capitalism and socialism are systems that could have currency, communism doesn't have currency.
Whatever the case the villagers still trade with currency. I'm just looking for a word that sounds more socialist/communist than a mall, because even though malls could exist in socialism, they remind me of the capitalist consumerist culture.
In Russian it's торговый центр (torgovy center), галерея, пассаж (galereya passash), торгово-развлекательный комплекс (torgovo-razvlekateliny kompleks), молл (moll)
As emergency substitute we could also just call it Wal Marx. Or Spawntown Wall Marx since it's next to the wall.
