Laundromat style room? plans did say laundry in this location.
Regarding the stairs, here are my thoughts. They will be used for evictions and also access to the secret area. Now going off the storm promo you see housemates left behind, I think during the first week or possibly over a couple of weeks housemates will be evicted from the main house and placed into the secret area. Also some housemates might be placed into the house the first night but a snap first day eviction see's them moved into the secret area. The challenge BB will give them is to stay hidden for a week or 2 without being caught by the main house. BB will also give them tasks or challenges to do that could give them away to add some excitement to it. Could also be a variation of the series 3 house, just a thought.
After this task has completed the secret area will be used as a rewards area.
