Apparently exceeding all expectations. Because it is a showroom, and a customer doesn't have to bring any merchandise to the cashier, a lot of customers have pointed at a display and simply said "I want this exact look for my backyard". Not only did they go home with patio furniture, but also with all the accessories, which is where a good chunk of margin comes from.
The showroom has now been set up as a Christmas wonderland. It's pretty much a Christmas store now. Haven't been in it yet, but apparently it looks amazing.
It doesn't sound like any more of these will be built. It was a unique opportunity with Future Shop closing down next to that CT. It only works because it has removed large bulky items from the main store, giving the store more space for smaller items and a larger product selection. It also allows the store to set up good displays for every product, whereas they couldn't display everything without losing floor space in the main store.
