How do you add a house to your game on The Sims 3 for PS3 in which you got from The Exchange

once you download it, it gets saved into your console. just use a phone or computer and select "move" then choose the lot this saved house was meant for. when you move there it will be the basic preset home. go to "town map" and select your house. press "replace" and you will have options for the replacement. then just choose your saved house(usually on the far left). you still have to pay for everything in the house.
