It seems you've slightly misinterpreted this poll (along with some others here). I'm not asking about what activity in town that is your favorite, but rather which building, the house in itself.
For me I picked the Treasure Chest Contest House. Mainly because it's actually ridiculously large...
Last week's Question: In BotW 2, which of these ruins from BotW would you like to see rebuilt and repopulated the most?
Third Place: Outpost (16.7%)
Second Place: Tabantha Village (25.0%)
First Place: Mabe Village (41.7%)
Hmm, fairly few responses to last weeks poll... Maybe it was a bit too...
