I second the comments about storage. One house we lived in had a *fantastic* laundry. It was attached to the main house but you walked two steps out the back door to go into it (so you could access it directly from the back yard too). It was large enough to have washing machine, dryer, deep freeze & a work bench on one wall, and the opposite wall was full of fantastic cupboards!!! Much tidier, less dusty etc than keeping things in the shed. We could also probably have rigged up some clever drying racks etc for when the weather was bad but we weren't there long enough (sadly, it was a great house). I loved that laundry and have since dreamed about building one onto this house
