My sister's 1993 machine (she moved into the house c. June 1993 and bought the machine new) is in a laundry closet. Originally the home (Marin County, CA) had a one-car attached garage, and the laundry was located in the garage, as is often the case in California, particularly in regions where it's not hot enough to need or have A/C. Placement of the dryer in the garage helps keep the house cooler in summer, plus there is the safety advantage of the garage slab being 6" lower than the floor of the house, in case there is a flood.
The previous owner was a building contractor and, to please his wife, he built a new two-car garage on the other side of the house, and connected it to the with a covered breezeway. The new garage had no plumbing connections, and the old one-car garage was insulated, given a new roof with skylight, and turned into a family room.
He built a laundry annex off the hallway where the bedrooms are located, thus imparting on this single story home the same effect as an upstairs laundry room has on a two-story home: the laundry area is near the bedrooms. He had to infringe an approx. 4 x 7 foot space into the back yard in order to pour a slab and erect walls and a roof. The annex is closed off from the hall by two sliding V-doors (accordian style) whose panelling matches the bedroom doors. If the doors were closed and you walked by it, you might think it was a double wide linen closet.
The only downside is laundry noise: her machines, while rugged, are not particularly quiet, so she doesn't say put a load of towels in the dryer just before bedtime. Even with the annex doors closed, you can still hear the machines running from her bedroom.
I have never measured the depth of the annex with the doors closed. If her Maytag ever fails to the point where it cannot be fixed, or if she one day gives the machine away and buys a FL, depth will have to be carefully considered. I am not certain that the new, larger FLs, with 31-32" depth, would fit, plus one must account for the washer door being left ajar most of the time and the sliding doors would need to clear that obstacle. The annex was designed in the early 1990s with a TL in mind. Hopefully her Dependable Care washer will give her a couple of more decades of service. My aunt's Maytag from 1965 was just replaced two years ago, it gave her more than forty years of service (it had been repaired a few times, however).
