Opening he shed is important (for some people) in Virtual Families because you will be able to put out oven fires and get a trophy. To open the shed you must drag a person over 14 into the sandbox where the gold doorknob is, and they will go fix the shed. After the doorknob is in, drag your person over the "Welcome" doormat and he will go unlock the shed. After that, you will get the trophy "The shed", and if there is a oven fire, you can drag your person to the shed, and he will put out the oven.
